This valuable study shows that distinct midbrain dopaminergic axons in the medial prefrontal cortex respond to aversive and rewarding stimuli and suggest that they are biased toward aversive processing. The use of innovative microprism based two-photon calcium imaging to study single axon heterogeneity is solid, although the experimental design could be optimized to distinguish aversive valence from stimulus salience and identity in this dopamine projection. This work will be of interest to neuroscientists working on neuromodulatory systems, cortical function and decision making.

This work identifies cnidarian neuropeptides and pairs them to their GPCR, then shows that neuropeptide signaling systems have evolved and diversified independently in cnidarians and bilaterians. Neuropeptide-receptor partners were experimentally identified using established and widely used methodologies including single cell mapping, providing compelling evidence for the conclusions of the paper. This impressive accomplishment provides fundamental new insights into the evolution of neuropeptide signaling systems and will be of broad interest to neurobiologists and evolution of development researchers.

The study by Chardon et al. is fundamental to advancing our understanding of presynaptic control of motor neuron output. Large-scale computer simulations were performed using well-established single motor neuron models to provide compelling evidence regarding the time-varying patterns of inputs that control motor neuron ensembles. The work will interest the community of motor control, motor unit physiology, neural engineering, and computational neuroscience.

In this valuable study, Parrotta et al. showed that it is possible to modulate pain perception and heart rate by providing false heart rate (HR) acoustic feedback before administering electrical cutaneous shocks. The evidence supporting the claims of the authors is rather solid, although what they consider an interoceptive signal is not necessarily supported as such by the results. In this regard, including a larger number of trials per participant, increasing the sample size, and adding a measure of actual pain perception after its induction would have strengthened the study. Although mechanisms and some alternative explanations for this effect remain to be addressed, the work will nonetheless be of interest to neuroscientists working on predictions and perception, health psychologists, pain researchers, and placebo researchers.

eLife assessment

The study presents valuable insights into the regulation of astrocytes in the long-term potentiation of excitatory synapses onto inhibitory interneurons. However, reviewers identified concerns regarding originality and proper acknowledgment of replicated work, representation of interneuron diversity, and the robustness of certain conclusions. The strength of evidence provided is deemed incomplete, necessitating significant revisions for clarity, and accuracy, and to address highlighted concerns.

eLife assessment

This valuable study uses a combination of behavioral studies and computational modeling to argue that humans implicitly represent gravity as a Gaussian distribution (rather than as a deterministic vector). The experimental evidence is generally solid, with all experiments and model simulations being consistent with the proposed account. However, in the current version of the manuscript, the evidence for the main claim of the paper is incomplete: a number of alternative interpretations such as uncertainty about the presence of external lateral forces, or uncertainty about other object properties have not been considered sufficiently.

eLife assessment

The authors have updated a helpful resource for the neuroscience community regarding hippocampal cell types and their interactions, called the "hippocampome." The updates expand content, tools, and potential applications, and therefore the significance is important. The strong presentation makes the paper compelling.

eLife assessment

This valuable study analyzed a large cohort of Adolescent Idiopathic Scoliosis (AIS) patients and identified an association with a variant in COL11A1 (Pro1335Leu). Experimental testing of this potentially pathogenic variant suggests a link between Pax1, Col11a1, Mmp3, and estrogen signaling. While the connection between transcriptional regulation, the extracellular matrix, and estrogen signaling is compelling, the experimental evidence supporting this link is still incomplete and would benefit from a more direct and comprehensive approach. Strengthening the functional testing would help establish the pathogenicity of a collagen variant and the role of the proposed Pax1-Col11a1-Mmp3 signaling axis in AIS.

eLife assessment

This paper presents important new data related to the non-canonical SMC complex MukBEF in E. coli, which remains less well understood compared to more canonical SMC complexes in many other bacteria. The authors use a combination of Hi-C and ChIP-seq to demonstrate that MukBEF loads at multiple locations along the chromosome, preferentially in newly replicated DNA, with the MatP/matS system antagonizing MukBEF activity and localizing in terminus proximal regions. Most of the data to support these findings are compelling, with modest concerns raised about the effect sizes of the ChIP-seq data, which could be bolstered with some additional controls.

eLife assessment

This fundamental study provides compelling evidence to explain how chemical variations within a set of kinase inhibitors drive the selection of specific Erk2 conformations. Conformational selection plays a critical role in targeting medically relevant kinases such as Erk2 and the findings reported here open new avenues for designing small molecule inhibitors that block the active site while also steering the population of the enzyme into active or inactive conformations. Since protein dynamics and conformational ensembles are essential for enzyme function, this work will be of broad interest to those working in drug development, signal transduction, and enzymology.

eLife assessment

This is a valuable contribution to the electric fish community, and to studies of active sensing more generally, in that it provides evidence that a well-studied behavior (chirping) may serve in active sensing rather than communication. For the most part, the evidence is solid. In particular, the evidence showing increased chirping in more cluttered environments and the relationship between chirping and movement are convincing. Nevertheless, evidence to support the argument that chirps are mostly used for navigation rather than communication is incomplete.

eLife assessment

The authors investigate the mechanism of amyloid nucleation in a cellular system using novel ratiometric measurements, providing fundamental insight into the role of polyglutamine length and the sequence features of glutamine-rich regions in amyloid formation. The problem addressed by this study is very significant and the ability to assess nucleation in cells is of considerable value. The data, as presented and analyzed, are mostly convincing.

While Bacterial Artificial Chromosomes libraries were once a key resource for building the human genome project over time they have been rendered relatively obsolete by long-read technologies. In the era of CRISPR-Cas systems pairing this data with one of the many guide-RNA libraries to find targets for manipulation with CRISPR tools is bringing back BACs advantages for genomics. With this in mind the authors have developed a BAC restriction map database containing the restriction maps for both uniquely placed and insert-sequenced BACs from 11 libraries covering the recognition sequences of available restriction enzymes. Alongside a set of Python functions to reconstruct the database and more easily access it (which were debugged and had improved documentation added during review). The presented data should be valuable for researchers simply using BACs, as well as those working with larger sections of the genome in terms of synthetic genes, large-scale editing, and mapping.

This work presents a new standardized graphical approach for visualizing genetic associations across a wide range of allele frequencies. These proposed TrumpetPlots have a distinctive trumpet shape, hence the proposed name. With the majority of variants having low frequency and small effects, while a small number of variants have higher frequency and larger effects, this view can help to provide new and valuable insights into the genetic basis of traits and diseases, and also help prioritize efforts to discover new risk variants. The tool is provided as a novel R package and R Shiny application and to demonstrate its use the article illustrates the distribution of variant effect sizes across the allele frequency range for over 100 continuous traits available in the UK Biobank. After some problems in testing the package is now available and easy to deploy via CRAN.

This is an important biophysical study combining native mass spectrometry with mutant cycles to estimate the thermodynamic components of lipid A binding to the ABC transporter MsbA. Binding energies for lipid-protein interactions are proposed, but the evidence is currently incomplete as they rely on a number of technical and theoretical assumptions, mostly related to multiple lipid binding sites in the protein.

eLife assessment

The manuscript represents an important contribution to an ongoing discussion about the substrate binding site and mechanism of the Bile Acid Sodium Symporter (BASS) family of transporters. Structural and biochemical analysis of a bacterial homolog, ASTBnm, in complex with its native substrate (not bile acids, but a vitamin A precursor, pantoate) show a new binding site that is consistent with classical proposals for elevator-type transport mechanisms. Molecular dynamics (MD) simulations highlight the improved stability for the substrate in the active site when ions are present, suggesting a binding order during the transport cycle. The structural studies, binding assays, and MD simulations are convincing.

eLife assessment

This important study combines a range of advanced ultrastructural imaging approaches to define the unusual endosomal system of African trypanosomes. Compelling images show that instead of a distinct set of compartments, the endosome of these protists comprises a continuous system of membranes with functionally distinct subdomains as defined by canonical markers of early, late and recycling endosomes. The findings suggest that the endocytic system of bloodstream stages has evolved to facilitate the extraordinarily high rates of membrane turnover needed to remove immune complexes and survive in the blood, which is of interest to anyone studying infectious diseases.

eLife assessment

This important study addresses mechanisms of feedback inhibition between planar cell polarity (PCP) protein complexes during convergent extension movements in Xenopus embryos. The authors propose an interesting model, in which non-canonical Wnt ligand stimulates transition of Dishevelled from its complex with Vangl to Frizzled, with essential roles of Vangl, Prickle and Ror in this process. The main functional observations supporting this model are convincing, but the immunoprecipitation data are incomplete and would benefit from additional clarification. With more rigorous approaches, this work will likely be of broad interest to cell and developmental biologists.

In this manuscript by Xiong L et al., through TLR2, the authors have uncovered an important link between innate immune signaling and hair regeneration. The authors provide convincing evidence supporting the critical roles of TLR2 in sensing CEP levels in hair follicles, counteracting the action of BMP signaling, and facilitating the activation of HFSCs during the hair cycle and wound repair. Importantly, the authors also propose that decreased CEP production and TLR2 expression might be factors contributing to the decreased hair regeneration associated with age-related and obesity-related hair thinning and hair loss phenotypes.

The authors carried out rigorous biochemical approaches, providing convincing evidence to support their conclusions.

eLife assessment

This important study advances our understanding of early Cambrian cnidarian paleoecology and suggests that the reconstructed ancestral feeding and respiration mechanisms predate jet-propelled swimming utilized by modern jellyfish. The work combines solid evidence of fluid and structural mechanics modeling, simulating for the first time the feeding and respiratory capacities in a microfossil (Quadrapyrgites), which in turn opens new possibilities using this approach for paleontological research. Assuming that the prior interpretations and assumptions concerning the modeled organism's soft part and skeletal anatomy are correct, the hypotheses that (1) the organism could alternately contract and expand the oral region and (2) such movement increased feeding efficiency seem plausible.

eLife assessment

This study examines the role of interaction between the PAS domain and the Cyclic Nucleotide-Binding Homology Domain (CNBHD) in voltage-dependent gating of EAG channels. The authors make the extraordinary claim that they have identified a hidden open state, thus providing a window for observing early conformational transitions associated with channel gating. Although the data are intriguing, the evidence supporting the conclusions is incomplete, and the experimental conditions used to propose the channel gating mechanism need to be revisited. With sufficiently strong experimental support, this work could become important for understanding the gating mechanisms of the KCNH family and would appeal to biophysicists interested in ion channels and physiologists interested in cancer biology.

eLife assessment

This important study reports biochemical and structural experiments that were carried out to determine the molecular basis of calcium-sensitive regulation of the guanine exchange factor Ric8A by the neuronal calcium sensor 1 (NCS-1). Structural and biochemical evidence for the NCS-1/Ric8A interface is convincing, but evidence for the full-length interactions is incomplete due to the low resolution of cryo-EM maps. This work will have important implications for scientists interested in G-protein signaling and molecular interactions that contribute to synapse function.

This is an important study that investigates the role of astrocytic Gi signaling in the anterior cingulate cortex in the modulation of extracellular L-lactate level and consequently impairment in flavor-place associates (PA) learning. However, whereas some of the behavioral observations and signaling mechanism data are compelling, the conclusions about effects on memory and the role of L-lactate are based on inadequate methods. With the addition of a few key experiments, this work will be of interest to neuroscientists studying learning and memory and the contribution of astrocytes to these processes.

eLife assessment

This important study delineates the molecular changes driving the progression from actinic keratosis (AK) to cutaneous squamous cell carcinoma (cSCC). Using state-of-the-art single-cell RNA profiling of 138,982 cells from 13 samples of six patients including AK, squamous cell carcinoma in situ (SCCIS), cSCC, and their matched normal tissues, thus covering comprehensive clinical courses of cSCC, the authors provide an invaluable data resource. This study identified several previously unreported and interesting candidate genes involved in different stages of the malignant progression of skin neoplasias, which have been validated in situ, and partially in vitro. Although data analysis needs improvement and comparison to other published data sets to fully support the claims and conclusions, these findings substantially advance our understanding of the molecular changes leading to skin cancer.

eLife assessment

This manuscript provides a useful qualitative analysis of hair extracts from mammals, with the goal of understanding how mosquitoes encode the chemicals in the odor. The data were collected using standard spectrometric approaches in the field of chemical ecology, but they suffer from artifacts associated with the sampling approach and analyses, and are limited in their replicates and sampling which may prevent inter-species comparisons at this point. Without additional analysis, the evidence supporting the claims currently remains unfortunately incomplete.

eLife assessment

This study presents a valuable comparison of the transcriptome and translatome between Drosophila neurons and glia. The data were collected and analyzed using validated methodology and the paper reports extensive variation in the translation efficiency of specific transcripts between neurons and glia. The authors argue that glia actively suppress the translation of neuronal transcripts by retaining ribosomes in their 5' leader regions. However, whereas the transcriptome and translatome analyses are convincing, the functional analyses are incomplete and would benefit from more rigorous validation to support the proposed model without over-interpretation.

This valuable manuscript investigates the roles of DKK3 in AD synapse integrity. Although previous work has identified the involvement of Wnt and DKK1 in synaptic physiology, this study provides compelling evidence that suppression of DKK3 rescues the changes in excitatory synapse numbers, as well as memory deficits in an established AD model mice. The authors provide both gain and loss of function data that support the main conclusion and advance our understanding of the mechanisms by which Wnt pathway mediates early synaptic dysfunction in AD models.

This important study points out discrepancies between the clinical diagnosis of Clostridioides difficile infection and the lack of detectable C. difficile in gut microbiome samples, as well as different relationships between asymptomatic C. difficile carriage and adult or infant gut microbiota compositions. While the solid analysis of a comprehensive and diverse metagenomic dataset suggests an over-diagnosis of C. difficile infection and an under-diagnosis of other putative enteric pathogens, the work requires addressing the detection limitations of the approach to be more convincing. This work will interest microbiologists and clinicians concerned with understanding the role of C. difficile in gut microbiota health and dysbiosis.

FKBP35 is the only FK506-binding protein present in the malaria-causing parasite Plasmodium falciparum, and has been considered a promising drug target due to its high affinity to the macrolide compound FK506, an immunosuppressant with antiplasmodial activity. This study demonstrates the essentiality of FKBP35 in parasite growth, based on compelling genetic evidence. The data also suggest that FK506 may exert its antimalarial activity through FKBP35-independent mechanisms that have not yet been characterised. This important study will be of interest to scientists working on the parasite biology and antimalarial drug development.

This study reports the discovery of a new circuit mechanism for light-avoidance behavior in the marine annelid, Platynereis dumerilii. Using calcium imaging, molecular perturbations, behavioral measurements, and modeling, the authors provide compelling evidence that nitric oxide is released by postsynaptic neurons onto ciliary photoreceptors to prolong and enhance their response to ultraviolet light. The fundamental new role of nitric oxide described in this study may be conserved across animal phyla and thus will be of broad interests to neuroscientists and neuroendocrinologists.

This important manuscript reveals signatures of co-evolution of two nucleosome remodeling factors, Lsh/HELLS and CDCA7, which are involved in the regulation of eukaryotic DNA methylation. The results suggest that the roles for the two factors in DNA methylation maintenance pathways can be traced back to the last eukaryotic common ancestor and that the CDC7A-HELLS-DNMT axis shaped the evolutionary retention of DNA methylation in eukaryotes. The solid evolutionary analyses form a strong basis for experimental follow-up studies. The work should be of interest to colleagues in the fields of evolutionary biology, chromatin biology and genome biology.

This study highlights new insights into the mechanism of pheochromocytoma pathogenesis that remains poorly understood. In the context of hereditary syndromes, such as multiple endocrine neoplasia 2 (MEN-2), where RET mutation is the major driver of thyroid, parathyroid, and adrenal pathologies, including pheochromocytoma, this mechanistic dissection of RET and TMEM127 is fundamentally sound. While the significance was deemed important, the strength of the evidence was found to be solid, although additional validation work would strengthen the findings.

The study used slice physiology and modeling to investigate neurotransmitter release at the cerebellar parallel fiber-to-molecular layer interneuron synapse, revealing that each docking site can accommodate up to two synaptic vesicles simultaneously. The authors have provided convincing evidence addressing how many vesicles can be released by a single release site in a short time. These findings are important for the validation of a two-step docking model and shed light on the mechanisms underlying short-term synaptic plasticity and strategies for achieving synaptic reliability, which plays a critical role in information processing in the brain.

Pak et al. examined the relationship between the most common spatial patterns of neurodegeneration and the density of different cell types in the cerebral cortex. The study uses innovative methods but the main claims are incompletely supported due to some limitations. While the results might be considered preliminary, this work provides valuable findings and takes a step in the right direction by highlighting the contribution of non-neuronal cell type to the pathobiology of neurodegeneration.

This fundamental study substantially advances our understanding of the role of zinc in metabolism, specifically a newly established clinical link between mutations in the zinc transporter SLC39A5, elevated serum zinc levels, and a reduction in the risk of Type 2 Diabetes. The provided evidence is solid with state-of-the-art genetic analysis of large human cohorts followed by a comprehensive analysis of a mouse SLC39A5 knockout mutant, establishing that SLC39A5 plays a role in hepatic lipid handling through AMPK signaling, although the limited analysis of a pancreatic phenotype that has previously been described constitutes a weakness. This study will be of relevance to researchers interested in metabolism, fatty liver disease, and the biology of trace elements.

eLife assessment

This valuable study provides a new perspective on preparatory activity occurring before the onset of movement. The authors report that, for a wide variety of recurrent networks, the optimal inputs should start before the desired network output. The authors present convincing evidence by combining mathematically tractable analyses in linear networks and numerical simulation in nonlinear networks. One limitation is that the only cost function considered for the input is that of magnitude. While this constraint is reasonable, it is suspected that other cost functions could lead to greater realism of model responses.

eLife assessment

This valuable study advances our knowledge of the effects of anxiety/depression treatment on metacognition, demonstrating that treatment increases metacognitive confidence alongside improving symptoms. The authors provide convincing evidence for the state-dependency of metacognitive confidence, based on a large longitudinal treatment dataset. However, it is unclear to what extent this effect is truly specific to treatment, as changes in metacognitive confidence in the group receiving online CBT were not statistically different from those in the control group.

eLife assessment

In this fundamental study, the authors propose analytical methods for inferring evolutionary parameters of interest from sequencing data in healthy tissue relevant to hematopoiesis. By combining analyses of single cell and bulk sequencing data, the authors can use a stochastic process to inform different aspects of genetic heterogeneity. The strength of evidence in support of the authors' claim is thus compelling. The work will be of broad interest to cell biologists and theoretical biologists.

eLife assessment

This important study identifies a spatial pattern of neural activity that corresponds to trust in an investment game. It provides a compelling assessment of the validity of this pattern by assessing its expression, or lack thereof, in a variety of datasets. This work, and the "neurometrics" approach it proposes, will be of broad interest to psychology researchers more generally.

eLife assessment

This important study advances our understanding of how listeners understand speech when there are multiple talkers by showing that the content of the speech affects acoustic processing. The evidence is generally solid, although additional details on the methods to allow replication would strengthen the study. The work will be of use to researchers interested in the neuroscience of speech and language processing.

eLife assessment

This is an important contribution that extends earlier single-unit work on orientation-specific center-surround interactions to the domain of population responses measured with Voltage Sensitive Dye (VSD) imaging and the first to relate these interactions to orientation-specific perceptual effects of masking. The authors provide convincing evidence of a pattern of results in which the initial effect of the mask seems to run counter to the behavioral effects of the mask, a pattern that reversed in the latter phase of the response. It seems likely that the physiological effects of masking reported here can be attributed to previously described signals from the receptive field surround.

eLife assessment

The primary goal of this paper is to examine microtubule detyrosination as a potential therapeutic target for axon regeneration. The valuable findings of this study provide convincing evidence for mechanistic links between microtubule detyrosination and neurite outgrowth in vitro and some evidence for axon regeneration in vivo.

eLife assessment

This important work presents an interesting perspective for the generation and interpretation of phase precession in the hippocampal formation. Through numerical simulations and comparison to experiments, the study provides a convincing theoretical framework explaining the segregation of sequences reflecting navigation and sequences reflecting internal dynamics in the DG-CA3 loop. This study will be of interest for researchers in the spatial navigation and computational neuroscience fields.

eLife assessment

This important study uses calcium imaging in mice to advance our understanding of the effect of antipsychotic drugs on neural functioning. The evidence supporting the conclusions is convincing, though some improvements could be made to the statistical testing of the data. This work will be of interest to neuroscientists working on visual processing and psychosis researchers.

eLife assessment

This is an important study that improves gene models for the ferret genome and identifies neural progenitors that are comparable to those found in developing human brains. The data are convincing and clearly presented. Of particular interest to the field, the work identifies enriched expression of FOXJ1 in late truncated radial glia, strongly indicating that towards the end of neurogenesis, these cells likely give rise to ependymal cells. The work is of interest to anyone studying the development of the nervous system, especially colleagues studying the evolution of development.

eLife assessment

This manuscript will provide a valuable method to evaluate the safety of MR in patients with orthopaedic implants, which is required in clinics. A strength of the work is that the in-silicon testbed is solid, based on the widely available human project, and validated. In addition, the toolbox will be open for clinical practice.

eLife assessment

This is important work that examines hepatic acetate production via ACOT12/18 in starvation and diabetes. The investigators use solid loss of function strategies in cells, including mouse primary hepatocytes, and in vivo mouse experiments to show that ACOTs are necessary for normal acetate production in the context of fasting and type 1 diabetes. Given that acetate is commonly thought to primarily represent a fermentation product, this study is of interest as it describes hepatic pathways converting fatty acids to acetate.

eLife assessment

The authors develop a cell culture system for studies of muscle tissue development and homeostasis. They convincingly validate a novel 3D cell model. Their thorough molecular and functional characterization will make this useful for future workers in the field.

eLife assessment

This fundamental study advances our understanding of the cell specific treatment of cone photoreceptor degeneration by Txnip. The evidence supporting the conclusions is convincing with rigorous genetic manipulation of Txnip mutations, however, there are a few areas in which the article may be improved through further analysis and application of the data. The work will be of broad interest to vision researchers, cell biologists and biochemists.

eLife assessment

This useful study presents convincing evidence that blood meal source and season affect Culex quinquefasciatus mosquito reproduction. Its unique focus on the interactive effects of both factors on mosquito fitness is of considerable relevance for the field, but the work suffers from inadequate experimental design - no replication, a population mismatch with the hypothesis region, and small sample sizes, limitations that were not sufficiently acknowledged in the discussion. The work will be of interest to those studying malaria and vector-borne diseases.

eLife assessment

This important study introduces a new therapeutic cell targeting system, where an active molecule is divided into inactive or less active parts that are subsequently linked via a bridging receptor on a target cell. Solid experimental proof of concept involving the activation of Wnt signaling in hepatocytes is presented, which could be further strengthened by demonstrating the specificity of the effect when applied to a mix of different cell types. This study may be of substantial interest to medical biologists focused on targeted therapeutics or seeking to utilize cell type-specific pathway modulation in their research.

eLife assessment

This study provides an important demonstration of how the false-positive rate of high-resolution 2D template matching to find particles of a given target structure in 2D cryo-EM images (2DTM) relates to overfitting the data towards the template. The authors present new methods to measure the amount of model bias that gets introduced in high-resolution features of such maps, with compelling evidence that high-resolution features that are not present in the template can still be reconstructed in 3D from images obtained by 2DTM. The paper could be strengthened by the inclusion of a more elaborate discussion (and possibly additional experiments) to describe the limitations of 2DTM for smaller target structures.

eLife assessment

This study presents valuable findings on the role of the small GTPase Rab3A in homeostatic plasticity. While the study demonstrates that Rab3A is required for homeostatic scaling, the evidence supporting the model put forward by the authors is incomplete. The work will be of interest to researchers in the field of synaptic transmission and plasticity.

eLife assessment

This is an important study that addresses a significant question in microbiome research. The authors provide convincing evidence that certain bacterial groups within the fly microbiome have critical functions for host development.

eLife assessment

This manuscript analyzes large-scale Neuropixels recordings from visual areas and hippocampus of mice passively viewing repeated clips of a movie and reports that neurons respond with elevated firing activities to specific, continuous sequences of movie frames. The important results support a role of rodent hippocampal neurons in general episode encoding and advance understanding of visual information processing across different brain regions. The strength of evidence for the primary conclusion was found to be convincing.

eLife assessment

This is an important study that tests the effects of using neurofeedback, in the form of reward delivery when large sharp wave-ripples (SWRs) are detected, on neurophysiological and behavioral measures. The authors provide convincing evidence that the rate of SWRs increased prior to reward delivery and decreased in the period after reward delivery, with no significant effect on memory performance. The ability to manipulate SWR rate in a naturalistic way is a potentially exciting new tool for studies that seek to understand the function of SWRs.

eLife assessment

This manuscript represents a cleanly designed experiment for assessing biological motion processing in children (mean age = 9) with and without ADHD. The group differences concerning accuracy in global and local motion processing abilities are solid, but the analyses suggesting dissociable relationships between global and local processing and social skills, age, and IQ need further interrogation. The results are useful in terms of understanding ADHD and the ontogenesis of different components of the processing of biological motion.

eLife assessment

In this important study, the authors develop a promising experimental approach to a central question in ecology: What are the contributions of resource use and interactions in the shaping of an ecosystem? For this, they develop a synthetic ecosystem set-up, a variant of SELEX that allows very detailed control over ecological variables. The evidence is convincing, and the work should be of broad interest to the ecology community, leading to further quantitative studies.

eLife assessment

This important paper reports on the redistribution of Pol V and DNA methylation from euchromatic to heterochromatic regions in H1 mutants. While some of the evidence is solid, other parts of the genome-level model proposed to explain the molecular phenotype of H1 mutants (which includes a reduction of DNA methylation at some euchromatic sites) would benefit from additional experimental support. The work will be of broad interest to individuals interested in the mechanisms that have evolved to partition eukaryotic genomes into euchromatic and heterochromatic regions.

eLife assessment

This important study combines experiments and theory to develop a sex-based in silico model of arterial myocytes. The ionic currents of the model and its sex difference based on experimental data and comparisons of model properties with experimental data at the single cell and tissue scale are convincing. If the rigor used to assess the model (specifically the simplicity of the 1D vessel model) was improved, and there was an addition of quantitative analysis of the data examining similarity between male/female experimental/simulation, the paper would be improved.

eLife assessment

The study by Deichsel et al. reports valuable findings that suggest a new, possibly conserved, mechanism by which post-translational modification of a Notch regulator mediates the cellular immune response. However, the claims are only partially supported as the data and analysis are incomplete. The work will be of interest to biologists working on immune cell development or regulation of Notch.

eLife assessment

In this valuable study, patients homozygous for both minor frequency alleles of the APOL1 gene are shown to be at significant risk for progression into sepsis after infection. The study has enrolled a significant number of subjects and provides solid results. The study addresses to infectious diseases and critical care experts and one major weakness is the lack of inclusion of non-Black patients.

eLife assessment

This study presents a rather valuable finding that IQGAP1 interacts with TNFAIP2, which activates Rac1 to promote drug resistance in TNBC. The evidence supporting the claims of the authors is quite solid. The work will be of interest to scientists working on breast cancer.

eLife assessment

This study presents a valuable finding for the treatment of PCCs by sequencing 16 tumor specimens from five patients with pheochromocytomas by single-cell transcriptomics and proposing a new molecular classification criterion based on the sequencing results and characterization of tumor microenvironmental features. The evidence supporting the claims of the authors is solid, although the inclusion of more patient samples would strengthen the study's conclusions. The work will be of interest to clinicians or medical biologists working on rare pheochromocytomas (PCCs).

eLife assessment

The authors present a potentially useful model involving Ca2+ signaling in inflammasome activation. As it stands, it was felt that the data were not sufficient to support the model and the claims of the study are inadequately presented.

eLife assessment

This important study describes the discovery and further engineering of a red light-activated, chloride-conducting Channelrhodopsin (ACR) that could be used to inhibit neuronal activity. The authors were able to demonstrate some inhibition of neuronal activities in vitro and in vivo with 635 nm light, however the study was incomplete. Adequate controls and direct comparisons to the performance of already-established variants were missing, making it difficult to confirm the future utility of MsACR1 and raACR1.

eLife assessment

This paper describes a new complexity estimator for time series based on state-space modeling, which can directly decompose signal entropy in both time and frequency. The authors compare their estimator to Lempel-Ziv (LZ) complexity using a variety of time series neurophysiological data from humans and non-human primates. This represents a potentially valuable methodological contribution for existing studies using LZ complexity in their analyses, although the paper currently ignores much of the existing literature which has already developed related solutions to the same issues. The strength of the evidence supporting the superiority of the new complexity metric is currently incomplete, and should be backed by additional analyses.

eLife assessment

This paper presents an important contribution to the field of hippocampal registration by introducing a novel surface-based approach that utilizes the topological and morphological features of the hippocampus for anatomical registration across individuals, rather than volumetric-based methods commonly used in the literature. The study provides compelling evidence for the efficacy of this approach using histological samples from three different datasets and offers validation of the method through comparison with traditional volumetric registration. This is important work given the large number of studies that examine hippocampal shape, thickness, and function in large cohorts, providing strong support for the use of hippocampal unfolding methods in future studies.

eLife assessment

This important and compelling study investigates the problem of intracellular acidification induced by commonly-used optogenetic stimulating opsins. The low proton permeability of two high-performance opsins is shown to reduce photostimulated acidification. The findings may be of broad interest in the fields of neuroscience research and optogenetic therapies.

eLife assessment

This study presents important findings indicating that gradients of functional connectivity are present in the human foetal brain, and that these gradients develop further during gestation, particularly in multisensory brain regions. The study uses state-of-the-art connectomic mapping techniques. However, recent findings suggest that such gradients may reflect confounds within the analysis technique more than underlying brain functions. The evidence for the authors' claims therefore currently appears inadequate as it does not account for these potential confounds.

eLife assessment

This important study uses a combination of computational modeling and glutamate imaging to show how a particular synaptic organization referred to as space-time wiring has a limited contribution to a dendritic computation that occurs in the retina. The evidence supporting the claims of the authors is convincing, although the findings are largely confirmatory of previous modeling and experimental results. The work will be of interest to retinal neurobiologists and neurophysiologists interested in dendritic computations.

eLife assessment

The finding that Fusicoccin promotes locomotor recovery after spinal cord injury is useful, and the idea of harnessing small molecules that may affect protein-protein interactions to promote axon regeneration is interesting and worthy of study. However, the main methods, data, and analyses are inadequate to support the primary claim of the manuscript that a 14-3-3-Spastin complex is necessary for the observed Fusicoccin effects.

eLife assessment

Franke et al. explore and characterize the color response properties in the mouse primary visual cortex, revealing specific color opponent encoding strategies across the visual field. The data is solid; however, the evidence supporting some conclusions and details about some procedures are incomplete. In its current form, the paper makes a useful contribution to how color is coded in mouse V1. Significance would be enhanced with some additional analyses and resolution of some technical issues.

eLife assessment

This study presents valuable findings on the roles of the axon growth regulator Sema7a in the formation of peripheral sensory circuits in the lateral line system of zebrafish. The evidence supporting the claims of the authors is solid, although further work directly testing the roles of different sema7a isoforms would strengthen the analysis. The work will be of interest to developmental neuroscientists studying circuit formation.
