This important study by Lee and colleagues examined how neural representations are transformed between the olfactory tubercle (OT) and the ventral pallidum (VP) using single neuron calcium imaging in head-fixed animals trained in classical conditioning. They show that the dimensionality of neural responses is lower in the VP than in the OT and suggest that VP responses represent values in a more abstract form while OT contains more odor information, potentially enhancing odor contrast. The reviewers found the results overall convincing although the nature of OT responses needs to be investigated further.

Large scale cell movements occur during gastrulation in vertebrate embryos but their role in this major morphogenetic transition in formation of the body plan is poorly understood. Using the chick embryo model system, this study makes important advances using elegant methods to show that extension of the primitive streak during gastrulation, occurring through cell proliferation, polarisation and intercalation, and large-scale polonaise cell movements, can be uncoupled. Although the driving mechanism and precise role of these movements remains a mystery, the study provides convincing evidence for the uncoupling through independent approaches, the most creative of which are the effects shown after induction of a supernumerary primitive streak.

eLife assessment

In this important study, the authors identify distinct roles for the calcium sensors Synaptotagmin 7 and Doc2alpha in the regulation of asynchronous release and calcium-dependent synaptic vesicle docking in hippocampal neurons. The current work adds to the field by placing the role of the two proteins in a new context, where Synaptotagmin 7 acts to promote synaptic vesicle docking and capture after a stimulus, while Doc2alpha has a role in specifically driving the asynchronous component of release as a calcium sensor. The methods, data, and analyses provide convincing support for the conclusions.

eLife assessment

This important study used single-cell whole-brain imaging of the immediate early gene Fos to identify the brain areas recruited by two anesthetics, ketamine and isoflurane. The utilization of a custom software package to align and analyze brain images for c-Fos positive cells stands out as an impressive component of the approach. The results provide solid evidence that these anesthetics might induce anesthesia via different brain regions and pathways, and raw fos showed shared and distinct activation patterns after ketamine- v. isoflurane-based anesthesia. Though differences could also be due, as the authors note, to differences in dose and route of administration. This paper may be of interest to preclinical and clinical scientists working with anesthetic and dissociative drugs.

The strength of the evidence is solid, due to high variability across measures, perhaps in part attributable to a failure to include sex as a factor for measures known to be sexually dimorphic. This study is of interest to scientists interested in Down Syndrome and its treatment, as well as scientists who study disorders that impact multiple organ systems.

Maestri et al report the absence of phylogenetic evidence supporting codiversification of mammalian coronaviruses and their hosts, leading to the important conclusion that the evolutionary history of the virus and its hosts are decoupled through frequent host switches. The evidence for frequent host switching, derived from a probabilistic model of co-evolution, appears convincing, but evidence for quantitative statements about the time of the last common ancestor of extant mammalian coronaviruses remains incomplete. The results would be strengthened by a reconstruction of the evolutionary timescale and further investigation of robustness to sampling biases and unsampled diversity.

Editors Assessment:

One limiting factor in the adoption of spatial omics research are workflow systems for data preprocessing, and to address these authors developed the SAW tool to process Stereo-seq data. The analysis steps of spatial transcriptomics involve obtaining gene expression information from space and cells. Existing tools face issues with large data sets, such as intensive spatial localization, RNA alignment, and excessive memory usage. These issues affect the process's applicability and efficiency. To address this, this paper presents a high-performance open-source workflow called SAW for Stereo-Seq. This includes mRNA position reconstruction, genome alignment, matrix generation, clustering, and result file generation for personalized analysis. During review the authors have added examples of MID correction in the article to make the process easier to understand. And In the future, more accurate algorithms or deep learning models may further improve the accuracy of this pipeline.

eLife assessment

This study presents valuable findings on the role of the Drosophila ubiquitin-conjugating enzyme UBE2D/eff in maintaining proteostasis during aging. Protein levels of UBE2D decrease with age, and knockdown of UBED2 leads to an accumulation of ubiquitinated proteins, and a shortened lifespan that can be rescued by ectopic expression of the human homologous gene. The work supports a role of this ubiquitin conjugating enzyme in proteostasis, although the evidence is still incomplete. The study will be of broad interest to cell biologists working in aging and age-related diseases.

This useful study addresses the interesting and challenging problem of how neural networks (including possibly the brain) can optimize performance while multi-tasking. The authors address this problem by introducing an information-theoretic framework that balances the costs of control and of automaticity to achieve a desired level of overall performance. They present detailed analyses of this framework, but overall the manuscript is not easily accessible to a broad audience, and the supporting evidence is currently incomplete (but could be greatly improved with substantial revisions). They use information-theoretic terminology in non-standard ways that are not clearly explained, leading to difficulties in interpreting the framework and comparing it to other computational approaches, and the relationship between their findings and empirical data is not always clear.

The manuscript describes human intracranial neural recordings in the auditory cortex during speech production, showing that the effects of delayed auditory feedback correlate with the degree of underlying speech-induced suppression. This is an important finding, as previous work has suggested that speech suppression and feedback sensitivity often do not co-localize and may be distinct processes, in contrast with findings in non-human primates where there is a strong correlation. The strength of the evidence is solid, with appropriate experimental methods, data, and analysis, though some additional analysis would strengthen comparisons with past work.

This fundamental study substantially advances our understanding of the role of different-sized soil invertebrates in shaping the rates of leaf litter decomposition, using an experiment across seasons along an aridity gradient. The authors provide compelling evidence that the summed effects of all invertebrates (with large-sized invertebrates being more active in summer and small-sized invertebrates in winter) on decomposition rates result in similar levels of leaf litter decomposition across seasons. The work will be of broad interest to ecosystem ecologists interested in soil food webs, and researchers interested in modeling carbon cycles to understand global warming.

eLife assessment

This important work substantially advances our understanding of episodic memory in individuals with aphantasia, and sheds light on the neural underpinnings of episodic memory and mental imagery. The evidence supporting the conclusions is convincing, including evidence from a well-established interview paradigm complemented with fMRI to assess neural activation during memory recall. The work will be of broad interest to memory researchers and mental imagery researchers alike.

Amacrine cells are a heterogeneous and understudied set of retinal interneurons. This study presents valuable new insights into the structure, function, and circuit connectivity of a particular subset of wide field amacrine cells (WACs). The authors use an impressive set of techniques to study structural and functional properties of these cells and to establish their postsynaptic circuit partners. Evidence for the central conclusions is solid, although some of the most interesting results could be pursued more completely.

eLife assessment

This important study describes patterns of anatomical connectivity between the cortex and the thalamus using magnetic resonance imaging data in humans and non-human primates. The measures are related to numerous other modalities to develop a robust understanding of the organisation of the system. The authors provide solid evidence that there is a difference between sensory and association cortices in terms of their connectivity with the thalamus, which may have downstream effects on brain function. This work will be of interest to neuroscientists interested in the organization and dynamics of cortico-thalamic circuits.

eLife assessment

This important study introduces a new cortical circuit model for predictive processing. Simulations effectively illustrate that, with appropriate synaptic plasticity, a canonical layer 2/3 cortical circuit - comprising two classes of interneurons providing subtractive and divisive inhibition - can generate uncertainty-modulated prediction errors by pyramidal neurons. The model's effectiveness is supported by solid numerical analysis. Although the model is convincing and offers testable predictions, it currently lacks direct comparison to experimental data, and the presentation clarity could be improved. Nonetheless, the model is expected to be of great interest to those involved in cortical and predictive processing research.

eLife assessment

This study presents important findings on the differential activity of noradrenergic and dopaminergic input to dorsal hippocampus CA1 in head-fixed mice traversing a runway in a virtual environment that is familiar or novel. While the data appear to be rigorously analysed, and the observed divergence in the dynamics of activity in the dopaminergic and noradrenergic axons is solid, there are some methodological concerns that mean the strength of evidence is currently incomplete.

eLife assessment

Alpha-synuclein is a synaptic vesicle associated protein that is linked to a number of neurodegenerative disorders. In this manuscript, the authors provide compelling evidence of alpha-synuclein's interaction with E-domain synapsins as the main culprit mediating the suppression of neurotransmitter release and synaptic vesicle recycling by alpha-synuclein. This important work provides molecular mechanisms underlying alpha-synuclein functions.

eLife assessment

This important study proposes a new method for tracking neurons recorded with Neuropixel electrodes across days. The methods and the strength of the evidence are convincing, but the authors do not address whether their approach can be generalized to other brain areas, species, behaviors, or tools. Overall, this method will be potentially of interest to many neuroscientists who want to study long-term activity changes of individual neurons in the brain.

eLife assessment

This manuscript details a new method and tool for examining TDP-43 loss of nuclear and gain of cytoplasmic function in neurons. This is a valuable resource that does not rely on artificial knockdown or overexpression. While the authors seek to use this new system to induce disease-associated TDP-43 pathology), their overall evaluation is incomplete and requires further characterization to enhance the applicability and utility of this new tool.

Evaluation statement (17 January 2024; revised 31 January 2024)

Feng and colleagues investigate the molecular basis of lipid scrambling in a fungal member of the TMEM16 family of Ca²⁺-dependent lipid scramblases. These proteins possess a groove in their 3D structure that has been implicated in lipid scrambling, which the authors investigate in the absence and presence of Ca²⁺ using a combination of cryo-EM structure determination, mutagenesis and functional assays. Their closed-groove structure reveals a continuous file of lipid molecules around the catalytic groove region, providing a structural basis for lipid interaction with the protein. Additionally, the authors capture three novel states of TMEM16, completing the picture of conformational transitions that this protein undergoes. Strikingly, the authors show that both structure and distribution of the protein’s conformations depend on lipid composition and nanodisc scaffold protein.

Biophysics Colab considers this to be exceptional work and recommends it to scientists interested in plasma membrane lipid homeostasis and cryoEM.

(This evaluation by Biophysics Colab refers to version 2 of this preprint, which has been revised in response to peer review of version 1.)

This study presents an important finding on the splicing regulatory function of RBM7 and its functional impact in breast cancer metastasis. The evidence supporting the claims of the authors is solid, although the inclusion of more delineation of how RBM7 regulates NF-kB and coordinates splicing would have strengthened the study. The work will be of interest to scientists working on breast cancer.

eLife assessment

This useful study utilizes proteomics analysis across a large panel of 51 cancer cell lines to elucidate mechanisms underlying the sensitivity of cancer cells to high-dose vitamin C (Ascorbate). While the associations between specific molecular pathways and sensitivity to ascorbate are interesting, a major limitation is that the study is largely descriptive and incomplete, lacking evidence on the molecular underpinnings of cancer cells' sensitivity to high-dose vitamin C.

eLife assessment

This useful study proposes a role of lysosomal Ca2+ release in inflammasome signaling and metabolic inflammation. While the proposed model would be of considerable interest to the field of immunology if validated, the experimental approaches to study calcium dynamics are problematic, with one of several concerns being the transfection efficiency. The major claims of the paper are thus only incompletely supported.

eLife assessment

This important study uses a multi-pronged empirical and theoretical approach to advance our understanding of animal cognition. It presents convincing data on how differences in learning relate to differences in the ways that male versus female animals cope with urban environments, and more generally how reversal learning may benefit animals in urban habitats.

eLife assessment

This is an important study for understanding the pathogenesis of ulcerative colitis. It convincingly demonstrates reduced levels of the vesicular trafficking protein Rab7 in ulcerative colitis and Crohn's disease, leading to altered levels of calcium-activated chloride channel regulator 1 (CLCA1) and subsequent mucin dysregulation, highlighting Rab7's significance in gut homeostasis maintenance. The manuscript advances the field as it provides insights into a novel regulatory pathway implicated in ulcerative colitis, potentially paving the way for the development of targeted therapeutic interventions.

eLife assessment

Pluripotent stem cells can be obtained from embryos (embryonic stem cells, ESCs) or through induction by transfection (induced pluripotent stem cells, iPSCs). This valuable study uses semi-quantitative proteomics to compare both types of cells, finding interesting differences. The value of the study lies in demonstrating that ESCs and iPSCs cannot be used interchangeably. The conclusions are backed by solid data even if a greater number and diversity in ESC and iPSC clones would help in generalizing the observations.

eLife assessment

This fundamental study evaluates the evolutionary significance of variations in the accuracy of the intron-splicing process across vertebrates and insects. Using a powerful combination of comparative and population genomics approaches, the authors present convincing evidence that higher rates of alternative splicing tend to be observed in species with lower effective population size, a key prediction of the drift-barrier hypothesis. The analysis is carefully conducted and has broad implications beyond the studied species. As such, it will strongly appeal to anyone interested in the evolution of genome architecture and the optimisation of genetic systems.

eLife assessment

The present study provides valuable evidence on the neurochemical mechanisms underlying working memory in obesity. The authors' approach considering specific working memory operations (maintenance, updating) and putative dopaminergic genes is solid, though the inclusion of a more direct measure of dopamine signaling and further theoretical analysis and interpretation of findings would have strengthened the work.

eLife assessment

This study provides the fundamental insight that TGN46, a single-pass membrane protein, acts as a cargo receptor for proteins at the Trans-Golgi Network. The authors demonstrate that the luminal domain of TGN46 is crucial for the incorporation of the soluble secretory protein PAUF into CARTS, a class of vesicles mediating TGN to surface traffic. The data presented are compelling, yielding a clear model for the sorting of cargos destined for secretion.

eLife assessment

The study addresses a central question in systems neuroscience (validation of active inference models of exploration) using a combination of behavior, neuroimaging, and modelling. The data provided are useful but incomplete, missing critical detail. Additionally, some of the conclusions require a comparison model, and proper consideration of alternative explanations.

eLife assessment

This study reports important findings about new locomotory dynamics of crawling Drosophila larva based on imaging the reaction forces during larval crawling. The evidence with the new high-resolution microscopy method is compelling, as it significantly improves the spatial, temporal, and force resolution compared to previous methods for studying Drosophila larva and could be applied to other crawling organisms. The manuscript explains the new technology, WARP microscopy, and provides analysis of the data to characterize small animal behavior and discover new crawling-associated anatomical features and motor patterns. The work will be of interest to the broad neuroscience community interested in the mechanisms of locomotion in a highly tractable model.

eLife assessment

The microRNA lin-4, originally discovered in C. elegans, has a key role in developmental timing across species, but how its expression is developmentally controlled is poorly understood. Here, the authors provide convincing evidence that two MYRF transcription factors are essential positive regulators of lin-4 during early C. elegans larval development. These results provide important insight into the molecular nature of developmental timing that could have significant implications for understanding these processes in more complex systems.

eLife assessment

This important study combines a range of advanced ultrastructural imaging approaches to define the unusual endosomal system of African trypanosomes. Compelling images reveal that, unlike a conventional set of compartments, the endosome in these protists forms a continuous membrane system with functionally distinct subdomains, as defined by canonical markers for early, late, and recycling endosomes. The findings compellingly support that the endocytic system in bloodstream stages has adapted to support remarkably high rates of membrane turnover necessary for immune complex removal and survival in the blood. This research is particularly relevant to those investigating infectious diseases

eLife assessment

This fundamental study addresses the earliest events that enable plant roots to reorient growth in response to gravity. Compelling molecular and cell biological data establish that plasma membrane localization of the LAZY or NEGATIVE GRAVITROPIC RESPONSE OF ROOTS (NGR) protein family is required for rapid and polar redirection of D6 protein kinase, an activator of the PIN3 auxin transporter. This work complements and extends recent publications on the NGR family in gravity sensing (PMID: 37741279 and PMID: 37561884). Collectively these papers advance our understanding of rapid plant gravity sensing and response.
