    1. Penrose‘s theory promises a deeper level of explanation. He starts with the premise that consciousness is not computational, and it’s beyond anything that neuroscience, biology, or physics can now explain. “We need a major revolution in our understanding of the physical world in order to accommodate consciousness,“ Penrose told me in a recent interview. ”The most likely place, if we‘re not going to go outside physics altogether, is in this big unknown—namely, making sense of quantum mechanics.“↳ Nautilus Members enjoy an ad-free experience. Log in or Join now. He draws on the basic properties of quantum computing, in which bits (qubits) of information can be in multiple states—for instance, in the “on” or “off” position—at the same time. These quantum states exist simultaneously—the “superposition”—before coalescing into a single, almost instantaneous, calculation. Quantum coherence occurs when a huge number of things—say, a whole system of electrons—act together in one quantum state.↳It was Hameroff‘s idea that quantum coherence happens in microtubules, protein structures inside the brain’s neurons. And what are microtubules, you ask? They are tubular structures inside eukaryotic cells (part of the cytoskeleton) that play a role in determining the cell‘s shape, as well as its movements, which includes cell division—separation of chromosomes during mitosis. Hameroff suggests that microtubules are the quantum device that Penrose had been looking for in his theory. In neurons, microtubules help control the strength of synaptic connections, and their tube-like shape might protect them from the surrounding noise of the larger neuron. The microtubules‘ symmetry and lattice structure are of particular interest to Penrose. He believes “this reeks of something quantum mechanical.” ↳Still, you‘d need more than just a continuous flood of random moments of quantum coherence to have any impact on consciousness. The process would need to be structured, or orchestrated, in some way so we can make conscious choices. In the Penrose-Hameroff theory of Orchestrated Objective Reduction, known as Orch-OR, these moments of conscious awareness are orchestrated by the microtubules in our brains, which—they believe—have the capacity to store and process information and memory.↳“Objective Reduction” refers to Penrose‘s ideas about quantum gravity—how superposition applies to different spacetime geometries—which he regards as a still-undiscovered theory in physics. All of this is an impossibly ambitious theory that draws on Penrose’s thinking about the deep structure of the universe, from quantum mechanics to relativity. As Smolin has said, “All Roger‘s thoughts are connected … twistor theory, his philosophical thinking, his ideas about quantum mechanics, his ideas about the brain and the mind.”

      对于意识的本质问题,彭罗斯的理论提出了一种更深层的解读。他的理论基于一个前提假设,即意识无法被计算,而且它绝非神经科学、生物学和物理学现阶段能够解释的问题。

      在 2017 年的一次采访中,彭罗斯告诉笔者,「为了理解并认知意识,我们首先要经历一次对于物理世界的巨大认知变革。至于那个可以研究意识本质的领域,如果我们不打算完全脱离物理学范畴的话,那么该领域最有可能一直存在于那个巨大的谜题中,换句话说,我们首先要解开量子物理的谜题。」

      彭罗斯将量子计算的基本特性吸收到他的理论中,即每一比特的信息,即量子位(Qubit)可以同时表现为多种状态,比如同时既是「激活」的,又是「未激活」的。在一次几乎是瞬间完成的计算之前,这些量子态(Quantum States)并未聚合(Coalescing),而是同时存在的,即叠加态(Ssuperposition)。而量子相干性(Quantum Coherence)只有在大量事件在量子态下同时发生的时候才会出现——比如某系统中的大量电子相互作用。

      对此,哈默洛夫认为量子相干性发生于微管(Microtubule)中,这是一种大脑神经元内部的蛋白质结构。也许读者会好奇所谓微管到底是什么东西:它们是存在于真核细胞中的管状结构,可以把它看成是细胞骨架(Cytoskeleton)的一部分,它们可以在细胞活动时发挥决定性作用,这些细胞活动也包括细胞分裂在内,比如在有丝分裂时决定染色体的分离。

      哈默洛夫认为,这些微管就是彭罗斯一直在为自己理论寻找的一种「量子装置」。在神经元中,微管可以帮助控制突触的连接强度,而它们管状的结构可以帮助它们免受周围更大的神经元带来的噪音影响。这些微管的对称、晶格结构恰恰是彭罗斯最感兴趣的。他相信这样的特征「散发着某种量子物理的气味」。

      不过,想要对意识产生任何影响,你需要的不仅仅是随机且持续发生的量子相干性事件。这个过程首先要经过某种方式重组,或者重新经过精心的编排,人类正是因为这一重组过程才能做出有意识的选择。在彭罗斯与哈默洛夫提出的协同客观崩现(Orchestrated Objective Reduction,简称「Orch-OR」)理论中,他们认为人类大脑中的微管会精密编排、操纵这些有意识的瞬间,而正是这样的瞬间给了人脑处理信息并存储记忆的能力。

      所谓「客观崩现」的概念则要涉及到彭罗斯对量子引力——即叠加态如何应用于不同的多个时空几何结构——方面的观点,他也把该理论视为目前物理学尚未发现的理论。然而所有这一切都是一个不可能被验证的、野心勃勃的假说,这个假说不过是借鉴了彭罗斯在量子力学领域和相对论领域对宇宙深层结构的思考。正如斯莫林说过的另一句话:「罗杰的所有观点都是相互勾连的扭量理论(Twistor Theory),无论是他的哲学思想、那些关于量子力学的观点,还是关于人类大脑与心灵的观点。」

    1. The prefrontal leukotomy procedure developed by Moniz and Lima was modified in 1936 by American neurologists Walter J. Freeman II and James W. Watts. Freeman preferred the use of the term lobotomy and therefore renamed the procedure “prefrontal lobotomy.” The American team soon developed the Freeman-Watts standard lobotomy, which laid out an exact protocol for how a leukotome (in this case, a spatula) was to be inserted and manipulated during the surgery. Get a Britannica Premium subscription and gain access to exclusive content. Subscribe Now lobotomyThe use of lobotomy in the United States was resisted and criticized heavily by American neurosurgeons. However, because Freeman managed to promote the success of the surgery through the media, lobotomy became touted as a miracle procedure, capturing the attention of the public and leading to an overwhelming demand for the operation. In 1945 Freeman streamlined the procedure, replacing it with transorbital lobotomy, in which a picklike instrument was forced through the back of the eye sockets to pierce the thin bone that separates the eye sockets from the frontal lobes. The pick’s point was then inserted into the frontal lobe and used to sever connections in the brain (presumably between the prefrontal cortex and thalamus). In 1946 Freeman performed this procedure for the first time on a patient, who was subdued prior to the operation with electroshock treatment.The transorbital lobotomy procedure, which Freeman performed very quickly, sometimes in less than 10 minutes, was used on many patients with relatively minor mental disorders that Freeman believed did not warrant traditional lobotomy surgery, in which the skull itself was opened. A large proportion of such lobotomized patients exhibited reduced tension or agitation, but many also showed other effects, such as apathy, passivity, lack of initiative, poor ability to concentrate, and a generally decreased depth and intensity of their emotional response to life. Some died as a result of the procedure. However, those effects were not widely reported in the 1940s, and at that time the long-term effects were largely unknown. Because the procedure met with seemingly widespread success, Moniz was awarded the 1949 Nobel Prize for Physiology or Medicine (along with Swiss physiologist Walter Rudolf Hess). Lobotomies were performed on a wide scale during the 1940s; Freeman himself performed or supervised more than 3,500 lobotomies by the late 1960s. The practice gradually fell out of favour beginning in the mid-1950s, when antipsychotics, antidepressants, and other medications that were much more effective in treating and alleviating the distress of mentally disturbed patients came into use. Today lobotomy is rarely performed; however, shock therapy and psychosurgery (the surgical removal of specific regions of the brain) occasionally are used to treat patients whose symptoms have resisted all other treatments.

    1. Storytelling allows us to make sense of the world. Research from a multitude of fields suggests that story structures match human neural maps. What do a mother breastfeeding, a hug from a friend, and a story all have in common? They all release oxytocin, also known as the love drug. And it’s powerful: In a study by neuroscientist Paul Zak, participants who were given synthetic oxytocin donated 57 percent more to charity than participants given a placebo. Similarly, hearing information in narrative form results in a higher likelihood of pro-social behavior.

    1. when we attribute sensory experiences to 00:06:39 ourselves for instance like the experience of red or the experience of seeing blue the model is external properties and we think of there as being inner properties just like those external properties that somehow we are 00:06:52 um we are seeing immediately

      This comment suggests a Color BEing Journey. How can we demonstrate in a compelling way that color is an attribute of the neural architecture of the person and NOT a property of the object we are viewing?

      See Color Constancy Illusion here:

      Science shows that color is an experience of the subject, not a property of the object: https://youtu.be/fQczp0wtZQQ but what Jay will go on to argue, is that this explanation itself is part of the COGNITIVE IMMEDIACY OF EXPERIENCE that we also take for granted.

    1. If you’ve ever felt that you can’t focus on a task when you’re hungry — or that all you can think about is food — the neural evidence backs you up. Work from a few years ago confirmed that short-term hunger can change neural processing and bias our attention in ways that may help us find food faster.

    1. It’s as if we need the gravitational pull of both worlds to keep us on track, locked on a good and righteous path. Without both worlds pulling on us, we would crash into one, or simply lose our way, hurtling through the universe on our own, intersecting nothing, helping no one.

      As neuroscietist Beau Lotto points out, the Anthropocene is creating greater and greater uncertainty and unpredictability, but the one human trait evolution has created to help us deal with this is the sense of awe. See my annotation on Beau Lotto's beautiful TED Talk: How we experience awe and why it matters https://hyp.is/go?url=http%3A%2F%2Fdocdrop.org%2Fvideo%2F17D5SrgBE6g%2F&group=world

      In short, the sacred is the antidote to the increase in uncertainty and unpredictability as we enter into the space of the Anthropocene. Awe can be the leverage point to the ultimate leverage point for system change that Donella Meadows pointed out many years ago- it can lead to rapid shift in paradigms, worldviews and value systems needed to shift the system.

    1. Demand-side solutions require both motivation and capacity for change (high confidence).34Motivation by individuals or households worldwide to change energy consumption behaviour is35generally low. Individual behavioural change is insufficient for climate change mitigation unless36embedded in structural and cultural change. Different factors influence individual motivation and37capacity for change in different demographics and geographies. These factors go beyond traditional38socio-demographic and economic predictors and include psychological variables such as awareness,39perceived risk, subjective and social norms, values, and perceived behavioural control. Behavioural40nudges promote easy behaviour change, e.g., “improve” actions such as making investments in energy41efficiency, but fail to motivate harder lifestyle changes. (high confidence) {5.4}

      We must go beyond behavior nudges to make significant gains in demand side solutions. It requires an integrated strategy of inner transformation based on the latest research in trans-disciplinary fields such as psychology, sociology, anthropology, neuroscience and behavioral economics among others.

It takes a little bit of attention, but not that much attention.

      This takes a part Johann Hari's Guardian article Your attention didn’t collapse. It was stolen, but it does so mostly from a story/narrative perspective. Burnett is taking the story as a science article (it was labeled "psychology") when it's really more of a personal experience story with some nods to science.

      Sadly the story works more on the emotional side than the scientific side. It would be nice to have a more straightforward review of some of the actual science literature with some of the pros/cons laid out to make a better decision.

    1. In fact, the methodical use of notebooks changed the relationship between natural memory and artificial memory, although contemporaries did not immediately realize it. Historical research supports the idea that what was once perceived as a memory aid was now used as secondary memory.18

      During the 16th century there was a transition in educational centers from using the natural and artificial memories to the methodical use of notebooks and commonplace books as a secondary memory saved by means of writing.

      This allows people in some sense to "forget" what they've read and learned and be surprised by it again later. They allow themselves to create liminal memories which may be refreshed and brought to the center later. Perhaps there is also some benefit in this liminal memory for allowing ideas to steep on the periphery before using them. Perhaps combinatorial creativity happens unconsciously?

    1. I just bookmarked this article published today in Current Biology for later reading and annotation. While the article isn't specifically focused on memory, the fact that it touches on visual structures, emotion, music, and movement (dance) which are core to some peoples' memory toolkits, I thought that many here would find it to be of interest.

      One of the authors provided the following tl;dr synopsis:

      "Across the world, people express emotion through music and dance. But why do music and dance go together?

      We tested a deceptively simple hypothesis: Music and movement are represented the same way in the brain."

      For those who haven't integrated song or dance into their practices, searching around for the idea of songlines will give you some background on their possible uses.

    1. The result has not been a gratifying bulking up of our neural “muscle.” On the contrary, all the mental effort we’ve mustered over the past year has left many of us feeling depleted and distracted, unequal to the tasks that never stop arriving in our inboxes. When the work we’re putting in doesn’t produce the advertised rewards, we’re inclined to find fault with ourselves. Maybe we’re insufficiently gritty; maybe, we think, we’re just not smart enough. But this interpretation is incorrect.

      We've been gaslighting ourselves about how our brains work. It's not a muscle, having "grit", and many of our attempts at productivity are completely wrong.

    1. https://via.hypothes.is/https://finiteeyes.net/pedagogy/extending-the-mind/

      A well written review of Annie Murphy Paul's The Extended Mind. Matthew Cheney has distilled a lot out of the book from his notes with particular application to improving pedagogy.

      I definitely want to read this with relation to not only using it to improve teaching, but with respect to mnemotechniques and the methods oral and indigenous societies may have either had things right or wrong and what Western culture may have lost as a result. I'm also particularly interested in it for its applications to the use of commonplace books and zettelkasten as methods of extending the mind and tools for thought.

    2. Paul likes to quote the philosopher who first came up with the idea of the extended mind, Andy Clark, when he says that humans are “intrinsically loopy creatures”.
    3. I wondered about something outside the scope of her book, which is neurodivergence. The Embodied Mind looks at a wide range of studies that all seem to search for the qualities, behaviors, and tendencies of a typical mind. The typical mind, like the typical body, is a statistical figment, an abstraction from tens, hundreds, thousands, and millions of individual minds and bodies, each atypical in its own way. What happens, for instance, to the extended mind of someone with significant physical limitations? (Stephen Hawking seems to have extended his mind pretty well.) A fascinating sequel to Paul’s book might be something along the lines of Oliver Sacks’s writings, a study of neurodivergence, atypicality, and what they can tell us about how we live, learn, and work. As fascinating as the similarities between brains are the differences.

      Looking at neurodivergence within this framing can be an important extension.

      We're definitely not all the same and some of the differences and research on them can potentially help us all.

    1. Deep Reinforcement Learning and its Neuroscientific Implications In this paper, the authors provided a high-level introduction to deep RL, discussed some of its initial applications to neuroscience, and surveyed its wider implications for research on brain and behaviour and concluded with a list of opportunities for next-stage research. Although DeepRL seems to be promising, the authors wrote that it is still a work in progress and its implications in neuroscience should be looked at as a great opportunity. For instance, deep RL provides an agent-based framework for studying the way that reward shapes representation, and how representation, in turn, shapes learning and decision making — two issues which together span a large swath of what is most central to neuroscience.  Check the paper here.

    1. Music gives the brain a crucial connective advantage
      • Music’s benefits for the brain aren’t new, and this study provides further evidence that musical brains have better neural networks.
      • In fact, any challenging skill that requires intensive, long-time training can improve how your brain is interconnected - even if you’re an adult.
      • These findings come from a study of 150 brain scans with machine learning aid, where they counted the brain connections.
      • All musician brains were a lot more structurally and functionally connected than non-musicians.
    1. during the backward pass, feedback connectionsare used in concert with forward connections to dynamically invert the forward transformation,thereby enabling errors to flow backward
    1. Brains – especially younger ones, since they’re changing so much – really do need to anneal regularly to pay down their ‘technical debt’, and if they don’t, they grow brittle and neurotic. (Technical debt in the brain builds up as we twist our existing brain networks to accommodate new facts; this debt is ‘paid down’ when we enter high-energy states and let new brain networks which fit these constraints self-organize)

    1. To the brain, reading computer code is not the same as reading language Neuroscientists find that interpreting code activates a general-purpose brain network, but not language-processing centers.

      Summary of the article:

      • Understanding code is neither done by language centers, nor by mathematical centers of the brain — it’s a whole different ball game.
      • This comes from a researcher who’s studying how different cognitive functions relate to language processing parts of the brain.
      • The study involved young programmers who analysed code while their brains were scanned.
      • People either say that great coders are great at language, or great at maths - neither seems to be true, and there is no single specialized area that lights up from coding.
      • The test activated the multiple demand network in participants’ brains, a wide network for performing mentally challenging tasks.

    1. Found reference to this in a review of Henry Quastler's book Information Theory in Biology.

      A more serious thing, in the reviewer's opinion, is the compIete absence of contributions deaJing with information theory and the central nervous system, which may be the field par excellence for the use of such a theory. Although no explicit reference to information theory is made in the well-known paper of W. McCulloch and W. Pitts (1943), the connection is quite obvious. This is made explicit in the systematic elaboration of the McCulloch-Pitts' approach by J. von Neumann (1952). In his interesting book J. T. Culbertson (1950) discussed possible neuraI mechanisms for recognition of visual patterns, and particularly investigated the problems of how greatly a pattern may be deformed without ceasing to be recognizable. The connection between this problem and the problem of distortion in the theory of information is obvious. The work of Anatol Rapoport and his associates on random nets, and especially on their applications to rumor spread (see the series of papers which appeared in this Journal during the past four years), is also closely connected with problems of information theory.

The author criticizes claimed evidence of the existence of innate biological differences between men and women's minds as being faulty and exaggerated, and while taking a position of agnosticism with respect to inherent differences relating to interest/skill in 'understanding the world' versus 'understanding people', reviews literature demonstrating how cultural and societal beliefs contribute to sex differences.

    1. With this approach, neurons that show E-SARE–driven expression in response to stimuli are permanently labeled by the fluorescent protein during the time window specified by the drug
    2. Expression of a drug-inducible Cre recombinase downstream of E-SARE enabled imaging of neuronal populations that respond to monocular visual stimulation and tracking of their long-distance thalamocortical projections in living mice
    1. A technique common in rodents is the use of Cre recombinase lines that are inducible at specific developmental time points (Figure 3b). The most common form of inducible Cre is CreERT2, which contains a modified estrogen receptor binding domain that prevents Cre from entering the nucleus in the absence of a ligand
    2. strong promoters capable of driving expression of microbial opsins or fluorescent proteins in specific populations can exhibit leaky expression elsewhere. This low-level leak may be virtually undetectable as light responsiveness or fluorescence but can be a serious issue when expressing Cre recombinase.
    1. creating improved technologies for large-scale recordings of neural activity in the live brain is a crucial goal in neuroscience
    1. new toolkits for chronic labeling of active ensembles will provide a much awaited experimental basis to interrogate various aspects of neuronal circuits underlying long-term plastic changes of the brain, such as during nervous system development, during establishment of long-lasting remote memory over months, or in association with age-related neuronal changes over several years.

    1. The machinery that accomplishes these tasks is by far the most powerful and complex of the sensory systems. The retina, which contains 150 million light-sensitive rod and cone cells, is actually an outgrowth of the brain. In the brain itself, neurons devoted to visual processing number in the hundreds of millions and take up about 30 percent of the cortex, as compared with 8 percent for touch and just 3 percent for hearing. Each of the two optic nerves, which carry signals from the retina to the brain, consists of a million fibers; each auditory nerve carries a mere 30,000.
    1. Psychopathy is a personality disorder characterized by ‘a lack of empathy and remorse, shallow affect, glibness, manipulation and callousness.’ When individuals with psychopathy imagine others in pain, researchers have found that brain areas necessary for feeling empathy and concern for others fail to become active and connected to other important regions involved in affective processing and compassionate decision-making.
    2. When you are in an agreeable and comfortable situation it is more difficult to empathize with another person’s suffering. At a neurobiological level – without a properly functioning supramarginal gyrus – your brain has a tough time putting itself in someone else’s shoes.

      'They' literally can't help being selfish assholes

    3. The right supramarginal gyrus ensures that we can decouple our perception of ourselves from that of others. When the neurons in this part of the brain were disrupted in the course of a research task, the participants found it difficult to stop from projecting their own feelings and circumstances onto others. The participants' assessments were also less accurate when they were forced to make particularly quick decisions.
    4. In a study published in the Journal of Neuroscience on October 9, 2013, Max Planck researchers identified that the tendency to be egocentric is innate for human beings – but that a part of your brain recognizes a lack of empathy and autocorrects. This specific part of your brain is called the the right supramarginal gyrus. When this brain region doesn't function properly—or when we have to make particularly quick decisions—the researchers found one’s ability for empathy is dramatically reduced. This area of the brain helps us to distinguish our own emotional state from that of other people and is responsible for empathy and compassion.

    1. “Neuroscience research shows that the only way we can change the way we feel is by becoming aware of our inner experience and learning to befriend what is going inside ourselves.”
    1. Social support is not the same as merely being in the presence of others. The critical issue is reciprocity: being truly heard and seen by the people around us, feeling that we are held in someone else’s mind and heart. For our physiology to calm down, heal, and grow we need a visceral feeling of safety. No doctor can write a prescription for friendship and love: These are complex and hard-earned capacities. You don’t need a history of trauma to feel self-conscious and even panicked at a party with strangers — but trauma can turn the whole world into a gathering of aliens.
    2. In trauma survivors, Van der Kolk notes, the parts of the brain that have evolved to monitor for danger remain overactivated and even the slightest sign of danger, real or misperceived, can trigger an acute stress response accompanied by intense unpleasant emotions and overwhelming sensations. Such posttraumatic reactions make it difficult for survivors to connect with other people, since closeness often triggers the sense of danger. And yet the very thing we come to most dread after experiencing trauma — close contact with other people — is also the thing we most need in order to regain psychoemotional solidity and begin healing.
    3. This, he points out, is why we’ve evolved a refined mechanism for detecting danger — we’re incredibly attuned to even the subtlest emotional shifts in those around us and, even if we don’t always heed these intuitive readings, we can read another person’s friendliness or hostility on the basis of such imperceptible cues as brow tension, lip curvature, and body angles.

      The expression "manual means of making graphical representation" makes me think of photography as a memory aid or augmenting tool. Although, of course, it would not necessarily refer to a symbolic portrayal.

      Interestingly, neuroscience today affirms our memory is far from a simple pointing to the past function, but it actually alters or edits the memory itself each time we go back to it and probably the subject who remembers changes in the process. Could that be an example of how technological aids can augment our brain processing of memories?

      I have recently explored this idea on my blog in a post called As We May Remember (a wink to the Vannebar Bush essay) http://eltnotes.blogspot.com/2019/02/as-we-may-remember.html

    1. The well-defined goal of connectomics is an illusion. In reality, there are many possible goals. And which goal we choose depends on the scientific question we want to answer. Do we want a connectome or the connectome? Do we want the adult bauplan or the developmental arc? Do we want the connectome constant to all of a species, or the variation between them?

      a connectome is a full map of the brain and a bauplan seems to be an archetypical map of an organism's body. Here it's used figuratively I think. Maybe as a pun.

    1. there are about 87 billion neurons in one human brain

      And about 7000 connections to other neurons per neuron?

    1. Montreal Neurological Institute

      sharing all data associated with its research; no patents for 5 yrs (see video) - first major research institute of it's kind - check if this is really true?

    2. European Union, Japan and the United States

      Find out specifically which of these are "open" and if they are all focused on neuroscience?

    1. Routine meditators also retain more brain cells, while the rest of us lose 4% of ours as we age.
    2. According to set point theory, our attitude and behaviors have a bigger effect on our happiness than our external circumstances – and that’s good news for mindfulness. Mindfulness shapes our brain by increasing gray matter in areas related to attention, learning, self-awareness, self-regulation, empathy, and compassion.
    3. Mindfulness literally changes our brains, making some areas more responsive, interconnected, and dense. In particular, these are areas related to empathy (the insula); memory, emotion, and emotion regulation; and reward circuitry. In response to distressing stimuli, meditators see more activation in their prefrontal structures (for awareness) and less in their fear-driven amygdala.
    4. When our mind wanders during meditation, a group of brain areas called the “default mode network” activates. Scientists aren’t exactly sure what this network does – it may be directly involved in mind wandering or simply be carrying out brain maintenance when we aren’t thinking about anything in particular. As soon as we realize our mind is wandering during meditation, other brain regions for detecting relevant events light up. As we refocus our attention on the breath, the executive brain network takes over. Experienced meditators who repeat this process thousands of times start to show differences in the brain. They develop more connection between the self-focused part of the default mode network and brain regions for disengaging attention, which makes it easier to shut off that area of the brain when they realize their minds are wandering. Over time, meditation improves working memory, fluid intelligence, and standardized test scores.

    1. Just having positive experiences is not enough to promote last well-being. If a person feels grateful for a few seconds, that’s nice. That’s better than feeling resentful or bitter for a few seconds. But in order to really suck that experience into the brain, we need to stay with those experiences for a longer duration of time—we need to take steps, consciously, to keep that spotlight of attention on the positive. So, how do we actually do this? These are the three steps I recommend for taking in the good. I should note that I did not invent these steps. They are embedded in many good therapies and life practices. But I’ve tried to tease them apart and embed them in an evolutionary understanding of how the brain works. 1. Let a good fact become a good experience. Often we go through life and some good thing happens—a little thing, like we checked off an item on our To Do list, we survived another day at work, the flowers are blooming, and so forth. Hey, this is an opportunity to feel good. Don’t leave money lying on the table: Recognize that this is an opportunity to let yourself truly feel good. 2. Really savor this positive experience. Practice what any school teacher knows: If you want to help people learn something, make it as intense as possible—in this case, as felt in the body as possible—for as long as possible. 3. Finally, as you sink into this experience, sense your intent that this experience is sinking into you. Sometimes people do this through visualization, like by perceiving a golden light coming into themselves or a soothing balm inside themselves. You might imagine a jewel going into the treasure chest in your heart—or just know that this experience is sinking into you, becoming a resource you can take with you wherever you go.
    2. Another region is the frontal regions of the prefrontal cortex—areas involved in controlling attention. Again, this should be no surprise: They’re focusing their attention in their meditation, so they’re getting more control over it, and they’re strengthening its neural basis.
    3. You can use the mind to change the brain to change the mind for the better. This is known as “self-directed neuroplasticity.” Neuroplasticity refers to the malleable nature of the brain, and it’s constant, ongoing. Self-directed neuroplasticity means doing it with clarity and skillfulness and intention. The key to it is a controlled use of attention. Attention is like a spotlight, to be sure, shining on things within our awareness. But it’s also like vacuum cleaner, sucking whatever it rests upon into the brain, for better or worse.
    4. research has also shown that it’s possible to slow the loss of our brain cells. Normally, we lose about 10,000 brain cells a day. That may sound horrible, but we were born with 1.1 trillion. We also have several thousand born each day, mainly in the hippocampus, in what’s called neurogenesis. So losing 10,000 a day isn’t that big a deal, but the net bottom line is that a typical 80 year old will have lost about 4 percent of his or her brain mass—it’s called “cortical thinning with aging.” It’s a normal process. But in one study, researchers compared meditators and non-meditators. In the graph to the left, the meditators are the blue circles and the non-meditators are the red squares, comparing people of the same age. The non-meditators experienced normal cortical thinning in those two brain regions I mentioned above, along with a third, the somatosensory cortex. However, the people who routinely meditated and “worked” their brain did not experience cortical thinning in those regions.
    5. People who maintain some kind of regular meditative practice actually have measurably thicker brains in certain key regions. One of those regions is the insula, which is involved in what’s called “interoception”—tuning into the state of your body, as well as your deep feelings. This should be no surprise: A lot of what they’re doing is practicing mindfulness of breathing, staying really present with what’s going on inside themselves; no wonder they’re using, and therefore building, the insula.
    6. busy regions of the brain start stitching new connections with each other. Existing synapses—the connections between neurons that are very busy—get stronger, they get more sensitive, they start building out more receptors. New synapses form as well.
    7. more activation in the left prefrontal cortex is associated with more positive emotions. So as there is greater activation in the left, front portion of your brain relative to the right, there is also greater well-being. That’s probably in large part because the left prefrontal cortex is a major part of the brain for controlling negative emotion. So if you put the breaks on the negative, you get more of the positive. On the other hand, people who routinely experience chronic stress—particularly acute, even traumatic stress—release the hormone cortisol, which literally eats away, almost like an acid bath, at the hippocampus, which is a part of the brain that’s very engaged in visual-spatial memory as well as memory for context and setting. For example, adults who have had that history of stress and have lost up to 25 percent of the volume of this critically important part of the brain are less able to form new memories.
    8. And better understanding them means we can skillfully stimulate the neural substrates of those states—which, in turn, means we can strengthen them. Because as the famous saying by the Canadian scientist Donald Hebb goes, “Neurons that fire together, wire together.”
    1. during periods of mind-wandering, regions of the brain’s default mode network were activated. Then when participants became aware of this mind-wandering, brain regions related to the detection of salient or relevant events came online. After that, areas of the executive brain network took over, re-directing and maintaining attention on the chosen object. And all of this occurred within 12 seconds around those button presses.

      I'd be interested to see how sleep deprivation relates to this; I find my mind wanders easily when I haven't had enough sleep. Yet another reason to get more sleep to be happy and healthy.

    2. A particularly generative field is contemplative neuroscience, which involves collaborations between scientists and expert authorities in the traditions that have informed the concept of mindfulness.
    3. For example, when your mind wandered off in that meeting, it might help to know you’re slipping into default mode—and you can deliberately bring yourself back to the moment. That’s an ability that can improve with training.
    4. One brain area stood out in this analysis: the medial prefrontal cortex, a part of the default mode network that is particularly related to self-focused thoughts, which make up a good portion of mind-wandering content. It turns out that experienced meditators deactivated this region more quickly after identifying mind-wandering than people who hadn’t meditated as much
    5. more experienced meditators have increased connectivity between default mode and attention brain regions, and less default mode activity while meditating.
