David Byrne's Journal: 12.13.11: Odyshape
"We instinctively want to believe that a merit-based world exists—that with some hard work, focus, time, effort and perseverance, you too will be rewarded with the body you see on the billboard. The same also applies to our notions of economic well-being. As a result, you have Bill O’Reilly and Newt Gingrich (among many others) implying that poor people are poor simply because they aren’t trying hard enough (note the clever segue from Barbie to politics and economics). The implication is that poor people, or anyone who isn’t successful, just aren’t applying themselves or trying hard enough. Also, that less than fabulously attractive people similarly aren’t going to the gym enough. The corollary is that Bill and Newt are as wealthy as they are because they worked hard. This, excuse me, is bullshit…

Sadly, this dissonance between what is possible image wise, and what is being aimed for by many normal women, is making many of them nutso."

Synesthesia's blended senses - latimes.com
"The study of synesthesia has helped shift the way scientists think about the brain. In the past, they have focused on matching different areas with specific functions; now, the entire organ is viewed as a tapestry of interwoven connections.

"The whole system is a giant network," Eagleman says. "It's no longer sufficient to think about single areas in isolation."

Like synesthesia, many neurological disorders — such as schizophrenia, autism,Alzheimer's disease, depression and epilepsy — have been linked to abnormal communication between brain regions. The hope is that as neuroscientists learn about how the connections in the synesthetic brain differ from those in normal brains, they will also gain insight into how these differences develop — and how they sometimes manifest as harmful disorders."

The Syllabi: Researching Synesthesia
"The cause of synesthesia is still subject to research, but it’s generally believed to be the result of a genetic mutation on the X chromosome, explaining its dominance in woman and high heritability. Some researchers think its heritability could suggest an evolutionary benefit. Sickle cell anemia, for example, can be deadly, but also provides malaria immunity. Does synesthesia provide a similar benefit?

It might if you’re a mathmetician or an artist. One of the peculiarities of some forms of synesthesia is that equations are visualised in 3D space, which might help someone like physicist Richard Feynmann, another famous synesthete, with his work. David Hockney, also a synesthete, once told Robert Burton that when he was designing a piece of art intended to accompany a production of a Maurice Ravel piece, he listened to the relevant section of the score and “the tree painted itself.” It’s also been suggested that savants like Daniel Tammett get their incredible skills from…"

Blue Brain Project - Wikipedia
"The Blue Brain Project is an attempt to create a synthetic brain by reverse-engineering the mammalian brain down to the molecular level.
The aim of the project, founded in May 2005 by the Brain and Mind Institute of the École Polytechnique Fédérale de Lausanne (Switzerland) is to study the brain's architectural and functional principles. The project is headed by the Institute's director, Henry Markram. Using a Blue Gene supercomputer running Michael Hines's NEURON software, the simulation does not consist simply of an artificial neural network, but involves a biologically realistic model of neurons.[1][2][not in citation given] It is hoped that it will eventually shed light on the nature of consciousness.[citation needed]

There are a number of sub-projects, including the Cajal Blue Brain, coordinated by the Supercomputing and Visualization Center of Madrid (CeSViMa), and others run by universities and independent laboratories in the UK, US, and Israel."

The Persistence Of Memory | Wired Science | Wired.com
"The great mystery of memory is how it endures. The typical neural protein only lasts for a few weeks, the cortex in a constant state of reincarnation. How, then, do our memories persist? It’s as if our remembered past can outlast the brain itself.

But wait: the mystery gets even more mysterious. A neuronal memory cannot simply be strong: it must also be specific. While each neuron has only a single nucleus, it has a teeming mass of dendritic branches. These twigs wander off in every direction, connecting to other neurons at dendritic synapses (imagine two trees whose branches touch in a dense forest). It is at these tiny crossings that our memories are made: not in the trunk of the neuronal tree, but in its sprawling canopy.

This means that every memory – represented as an altered connection between cells – cannot simply endure. It must endure in an incredibly precise way, so that the wiring diagram remains intact even as the mind gets remade, those proteins continually recycled."

A Sharper Mind, Middle Age and Beyond - NYTimes.com
"To isolate the specific impact of schooling on mental skills, Dr. Lachman & her colleagues tried to control for other likely reasons one person might outshine another—differences in income, parental achievement, gender, physical activity & age. After all, we know that the children of affluent, educated parents have a raft of advantages that could account for greater mental heft down the road. College graduates are able to compound their advantages because they can pour more resources into their minds & bodies.

Still, when Lachman & Dr. Tun reviewed results, they were surprised to discover that into middle age and beyond, people could make up for educational disadvantages encountered earlier in life."

[This doesn't make much sense to me. Is this really the cause & effect? "[A] college degree appears to slow the brain’s aging process." Or are people inclined to go to college wired this way, or the jobs that they're likely to have after college allowing them to keep their minds sharp?]

Socrates' nightmare - The New York Times [Not buying all of this, but liking some material within]
"At the core of Socrates' arguments lay his concerns for the young. He believed that the seeming permanence of the printed word would delude them into thinking they had accessed the heart of knowledge, rather than simply decoded it. To Socrates, only the arduous process of probing, analyzing and ultimately internalizing knowledge would enable the young to develop a lifelong approach to thinking that would lead them ultimately to wisdom, virtue and "friendship with [their] god."

To Socrates, only the examined word and the "examined life" were worth pursuing, and literacy short-circuited both…

"Perhaps no one was more eloquent about the true purpose of reading than French novelist Marcel Proust, who wrote: "that which is the end of their [the author's] wisdom is but the beginning of ours." The act of going beyond the text to think new thoughts is a developmental, learnable approach toward knowledge."

Developing Your Creative Practice: Tips from Brian Eno :: Tips :: The 99 Percent
"1. Freeform capture. Grab from a range of sources without editorializing…<br />
<br />
2. Blank state. Start with new tools, from nothing, and toy around…<br />
<br />
3. Deliberate limitations. Before a project begins, develop specific limitations…<br />
<br />
4. Opposing forces. Sometimes it’s best to generate a forced collision of ideas…<br />
<br />
5. Creative prompts. In the ‘70s Eno developed his Oblique Strategies cards, a series of prompts modeled after the I Ching to disrupt the process and encourage a new way of encountering a creative problem. On the cards are statements and questions like: “Would anybody want it?” “Try faking it!” “Only a part, not the whole.” “Work at a different speed.” “Disconnect from desire.” “Turn it upside down.” “Use an old idea."…<br />
<br />
In the end, don’t underestimate your personal feelings about a project. Eno states: “Nearly all the things I do that are of any merit at all start off as just being good fun.” Amen to that."

The Rhetoric Of Neuroscience | Wired Science | Wired.com
"The language of neuroscience definitely fuels an “anxious parenting” mentality–everything you do molds the child’s brain, permanently influencing your child’s future life (job, mental health, intelligence, and so forth). This is scary stuff–some of the language I look at uses neuroscience to suggest that a single mistake at the wrong time (an aggressive tone, yelling at the child) can have permanent effects on the child’s emotional stability. Of course, we have always had various ways of promoting – as well as contesting – the anxious parenting mentality, so the neuroscientific version isn’t totally new, it’s just the latest reinvention. But the neuroscientific language and images give it a particularly persuasive quality that I think is especially nerve-wracking–popular magazine features tell us that we can see, on a second-by-second basis, how our every word and behavior are permanently influencing our child’s brain."

Handwriting Is History - Miller-McCune
"Writing words by hand is a technology that’s just too slow for our times, and our minds."<br />
<br />
"I transferred him to a private school where he was allowed to dictate his writing assignments. For his fourth-grade assignments, I sat at the computer, my laptop on the dining room table, as he paced the dining room, wildly gesticulating, sometimes stopping to put his hand on his chin in thought, but mainly speaking without stopping. I am a fast typist, but I could not keep up; I had to break his train of words. He spoke aloud in full clauses and paragraphs. What would have taken him about three or four hours (I am not exaggerating) by hand took him about four minutes by mouth."<br />
<br />
"The moral of the story is that what we want from writing — what Simon wants and what the Sumerians wanted — is cognitive automaticity, the ability to think as fast as possible, freed as much as can be from the strictures of whichever technology we must use to record our thoughts."

Oscillatory Thoughts: We are all inattentive superheroes
"…amazed by the actual experience of sensation. Even beyond the philosophical wonder of passively sampling our outside environment in a shared, meaningful fashion is the ridiculous sensitivity of our senses.<br />
<br />
We're used to thinking of our senses as being pretty shite: we can't see as well as eagles, we can't hear as well as bats, and we can't smell as well as dogs. Or so we're used to thinking.<br />
<br />
It turns out that humans can, in fact, detect as few as 2 photons entering the retina. 2. As in, 1-plus-1.<br />
<br />
It is often said that, under ideal conditions, a young, healthy person can see a candle flame from 30 miles away. That's like being able to see a candle in Times Square from Stamford, Connecticut. Or seeing a candle in Candlestick Park from Napa.<br />
<br />
Similarly, it appears that the limits to our threshold of hearing may actually be Brownian motion. That means that we can almost hear the random movements of atoms.<br />
<br />
We can also smell as few as 30 molecules of certain substances."

Does Depression Help Us Think Better? | Wired Science | Wired.com
"In other words, Thomson and Andrews imagined depression as a way of forcing the mind to focus on its problems. Although rumination feels terrible, it might make it easier for us to pay continuous attention to our dilemmas. According to Andrews and Thomson, the mood disorder is part of a “coordinated system” that exists “for the specific purpose of effectively analyzing the complex life problem that triggered the depression.” If depression didn’t exist — if we didn’t react to stress and trauma with endless ruminations — then we would be less likely to solve our predicaments."<br />

Jonah Lehrer on Buildings, Health and Creativity | Head Case - WSJ.com
"Although we're only starting to grasp how the insides of buildings influence the insides of the mind, it's possible to begin prescribing different kinds of spaces for different tasks. If we're performing a job that requires accuracy and focus (say, copy editing a manuscript), we should seek out confined spaces with a red color scheme. But for tasks that require a little bit of creativity, we seem to benefit from high ceilings, lots of windows and bright blue walls that match the sky."

Mishara's remarkable paper Kafka, paranoic doubles & the brain claims Kafka suffered from dream-like hallucinations during a sleep-deprived state while writing & his work "provides data about the structure of the human self…documents processes "that are not limited to the individual's experience of self in its historical context, nor the individual's 'autobiographical' memory, but reflect the very structure of human self as a transformative process of self-transcendence"."

Superfamous - Folkert Gorter
"Disclaimer: As you read this, you do not really see the pixels, the screen, your hands, and the surroundings, but an internal and three-dimensional image that reproduces them almost exactly and that is constructed by your brain. The photons emitted by your screen strike the retina of your eyes, which transform them into electrochemical information; the optic nerves relay this information to the visual cortex at the back of the head, where a cascade-like network of nerve cells separates the input into categories (form, color, movement, depth, etc.).<br />
<br />
How the brain goes about reuniting these sets of categorized information into a coherent image is still a mystery. This also means that the neurological basis of consciousness is unknown. (source = http://en.wikipedia.org/wiki/The_Cosmic_Serpent )"

This imagined edifice could then be walked through at any time in the future. Such a building would later come to be called a memory palace."<br />

"What began as an exercise in participatory journalism became an obsession. True, what I hoped for before I started hadn’t come to pass: these techniques didn’t improve my underlying memory (the “hardware” of “Rhetorica ad Herennium”). I still lost my car keys. And I was hardly a fount of poetry. Even once I was able to squirrel away more than 30 digits a minute in memory palaces, I seldom memorized the phone numbers of people I actually wanted to call. It was easier to punch them into my cellphone. The techniques worked; I just didn’t always use them. Why bother when there’s paper, a computer or a cellphone to remember for you?"

The Time Hack — Day 11: Watch paint dry
"But researchers argue that boredom, or taking breaks from the chaos of daily life, may actually be beneficial for you.<br />
<br />
With the use of brain imaging technology, neuroscientists have found that our brains may be highly active when in a state of rest, or when you are “bored”. In fact, the brain only uses 5% less energy in its resting state, compared to moments when a person is actively engaged in an activity.<br />
<br />
Additionally, psychologists argue the slight change in brain activity could have a dramatically positive influence on an individual’s perception of time. Like when you are asleep, time seems to slip by just a bit faster when you’re bored – making constructive, active moments in your day seem that much more dynamic and memorable."

You might experience conflict in your organization, project, or dealings with outside agencies. This could take the form of misunderstandings, miscommunication, unclear expectations, degraded dialog, threats, abusive language, violation of boundaries, or marginalization of perspectives.<br />
<br />
Unmitigated conflict can lead to psychological trauma, organizational dysfunction, social tension, diplomatic breakdown and violence.<br />
However, much good can come when conflict is properly acknowledged. Positive results can include expanded knowledge, role differentiation, appreciation for diversity, and new depth within relationships.<br />

Anosognosia - Wikipedia [via: http://readingbyeugene.com/2010/12/23/the-top-five-long-reads-of-2010/]
"Anosognosia is a condition in which a person who suffers disability seems unaware of the existence of his or her disability. Unlike denial, which is a defense mechanism, Anasognosia is rooted in physiology (for example, damage to the frontal or parietal lobe due to illness and disease). This may include unawareness of quite dramatic impairments, such as blindness or paralysis. It was first named by neurologist Joseph Babinski in 1914,[1] although relatively little has been discovered about the cause of the condition since its initial identification. The word comes from the Greek words "nosos" disease and "gnosis" knowledge (an- / a- is a negative prefix)."

Method of loci - Wikipedia, the free encyclopedia
"'the method of loci', an imaginal technique known to the ancient Greeks and Romans and described by Yates (1966) in her book The Art of Memory as well as by Luria (1969). In this technique the subject memorizes the layout of some building, or the arrangement of shops on a street, or any geographical entity which is composed of a number of discrete loci. When desiring to remember a set of items the subject literally 'walks' through these loci and commits an item to each one by forming an image between the item and any distinguishing feature of that locus. Retrieval of items is achieved by 'walking' through the loci, allowing the latter to activate the desired items. The efficacy of this technique has been well established (Ross and Lawrence 1968, Crovitz 1969, 1971, Briggs, Hawkins and Crovitz 1970, Lea 1975), as is the minimal interference seen with its use."

Instead, the impulse to overeat depends on the pleasures of the stomach and intestines, which have an uncanny ability to detect the presence of calories. When we reach for that third helping of turkey, we are obeying the wishes of the gut, following a bodily desire that's difficult to resist."

The Cognitive Cost Of Expertise | Wired Science | Wired.com
"Now for the bad news: Expertise might also come with a dark side, as all those learned patterns make it harder for us to integrate wholly new knowledge. Consider a recent paper that investigated the mnemonic performance of London taxi drivers. In the world of neuroscience, London cabbies are best known for their demonstration of structural plasticity in the hippocampus, a brain area devoted (in part) to spatial memory. Because the cabbies are required to memorize the entire urban map of London – it’s the most rigorous driving test in the world – their posterior hippocampi swell and expand, leading to permanent changes in the brain. Knowledge shapes matter."

Why Doesn't Anyone Pay Attention Anymore? | HASTAC [A response to: http://www.nytimes.com/2010/11/21/technology/21brain.html?pagewanted=all]
"We need to distinguish what scientists know about human neurophysiology from our all-too-human discomfort w/ cultural & social change. I've been an English professor for >20 years & have heard how students don't pay attention, can't read a long novel anymore, & are in decline against some unspecified norm of idealized past quite literally every year…we measure our kids' deficits by our glowing & often inflated idea of how much better "we" (our entire generation) were. This is not really a discussion about biology of attention; it's about sociology of change…Virtually all of our current institutions of learning have evolved to prepare youth for industrial age model of work…sit still, don't move, come on time, do this subject then that one in order to pass end-of-grade item-response test. Who wouldn't find video games more stimulating than a typical school day—& more relevant to challenges & obstacles ahead?…mismatch btwn way they are being taught & what they need to learn."

Children, Wired: For Better and for Worse — Daphne Bavelier, C. Shawn Green, and Matthew W.G. Dye [.pdf]
"Children encounter technology constantly at home and in school. Television, DVDs, video games, the Internet, and smart phones all play a formative role in children’s development. The term ‘‘technology’ subsumes a large variety of somewhat independent items, and it is no surprise that current research indicates causes for both optimism and concern depending upon the content of the technology, the context in which the technology immerses the user, and the user’s developmental stage. Furthermore, because the field is still in its infancy, results can be surprising: video games designed to be reasonably mindless result in widespread enhancements of various abilities, acting, we will argue, as exemplary learning tools. Counterintuitive outcomes like these, besides being practically relevant, challenge and eventually lead to refinement of theories concerning fundamental principles of brain plasticity and learning."

TPM: The Philosophers’ Magazine | Hacker’s challenge ["Peter Hacker tells James Garvey that neuroscientists are talking nonsense"]
“Philosophy does not contribute to our knowledge of the world we live in after the manner of any of the natural sciences. You can ask any scientist to show you the achievements of science over the past millennium, and they have much to show: libraries full of well-established facts and well-confirmed theories. If you ask a philosopher to produce a handbook of well-established and unchallengeable philosophical truths, there’s nothing to show. I think that is because philosophy is not a quest for knowledge about the world, but rather a quest for understanding the conceptual scheme in terms of which we conceive of the knowledge we achieve about the world. One of the rewards of doing philosophy is a clearer understanding of the way we think about ourselves and about the world we live in, not fresh facts about reality."

The Neurobiology of Evil | Going Mental | Big Think
"Is a person's propensity toward evil a matter of malfunctioning synapses and neurons?<br />
<br />
Michael Stone, professor of clinical psychiatry at Columbia University and author of “The Anatomy of Evil,” says it is. Ever-more-detailed brain scans are revealing the biological origins of psychological issues in "evil" people, from those who are mildly antisocial to serial murderers.<br />
<br />
Under each brain’s wrinkly cortex lies the limbic system, an evolutionary heirloom controlling emotion and motivation, among other functions. Within this limbic system is the amygdala, an almond-shaped cluster of nuclei that processes our feelings of fear and pleasure.<br />
<br />
Murderers and other violent criminals have been shown to have amygdalae that are smaller or that don’t function properly, explains Stone."

Human Connections Start With A Friendly Touch : NPR
"Social scientists have shown in many studies over the years that supportive touch can have good outcomes in a number of different realms. Consider the following examples: If a teacher touches a student on the back or arm, that student is more likely to participate in class. The more athletes high-five or hug their teammates, the better their game. A touch can make patients like their doctors more. If you touch a bus driver, he's more likely to let you on for free. If a waitress touches the arm or shoulder of a customer, she may get a larger tip.<br />
<br />
But why does a friendly or supportive touch have such universal and positive effects? What's happening in our brains and bodies that accounts for this magic?"

Are Distractible People More Creative? | Wired Science | Wired.com
"not enough to simply pay attention to everything—such a deluge of sensation can quickly get confusing. (Kierkegaard referred to this mental state as “drowning in possibility”. Some scientists believe that schizophrenia is characterized by extremely low latent inhibition coupled w/ severe working memory deficits…leads to a mind constantly hijacked by minor distractions.)…We need to let more info in, but we also need to be ruthless about throwing out useless stuff.

People bemoan infinite distractions of web, way we’re constantly being seduced by hyperlinks, unexpected search results, arcane Wikipedia entries. & yes, that’s all true—I just wasted 30 minutes searching for that Kierkegaard quote. (I ended up on a Danish culture website, which led me to a photography collection of Danish modern furniture…) But the problem isn’t distractibility per se—it's distractibility coupled w/ failure to curate our thoughts, to monitor relevancy of whatever is loitering in working memory."

You Are What You Touch: How Tool Use Changes the Brain's Representations of the Body: Scientific American
"A common illustration of just how flexible the sense of our body is comes from changes in the brain’s representation of the body due to tool use. Humans, and some other animals, are able to use tools as additions to the body. When we use a long pole to retrieve an object we couldn’t otherwise reach, the pole becomes, in some sense, an extension of our body. Is this merely a poetic way of speaking, or does the brain actually incorporate the tool into its representation of the body? Studies of monkeys learning to use a rake to obtain distant objects show that this may be more than a mere metaphor. Multisensory brain cells respond both to touch on the hand or visual objects appearing near the hand. When the monkeys used the rake, these cells began to respond to objects appearing anywhere along the length of the tool, suggesting the brain represented the rake as actually being part of the hand."

Perhaps we need to alter the fonts, or reduce the contrast, or invert the monochrome color scheme. Our eyes will need to struggle, and we’ll certainly read slower, but that’s the point: Only then will we process the text a little less unconsciously, with less reliance on the ventral pathway. We won’t just scan the words – we will contemplate their meaning."

"Have you ever fallen into a black hole of comparison shopping? You’re looking for a new digital camera, for instance. You head over to Cnet.com and read some reviews of various cameras, watch the video demos, identify the model you want. Then perhaps you employ Google’s shopping search to price out the options and find the best deal. All of the sudden, it’s four hours later. You’ve found the perfect camera, but your purchasing triumph is tainted by a creeping feeling of, well, disgust. Couldn’t that time have been used better?…<br />

What Is It About 20-Somethings? - NYTimes.com [This piece has popped up everywhere.]
"KENISTON CALLED IT youth, Arnett calls it emerging adulthood; whatever it’s called, the delayed transition has been observed for years. …“It’s somewhat terrifying,” writes a 25-year-old…“to think about all the things I’m supposed to be doing in order to ‘get somewhere’ successful: ‘Follow your passions, live your dreams, take risks, network w/ the right people, find mentors, be financially responsible, volunteer, work, think about or go to grad school, fall in love & maintain personal well-being, mental health & nutrition.’ When is there time to just be & enjoy?” Adds a 24-year-old: “…It’s almost as if having a range of limited options would be easier.”

While the complaints of these young people are heartfelt, they are also the complaints of the privileged.

The fact that emerging adulthood is not universal is one of the strongest arguments against Arnett’s claim that it is a new developmental stage. If emerging adulthood is so important, why is it even possible to skip it?"

Instead of celebrating our analytical powers, these experiments document our foibles & flaws…explore why human reason can so often lead us to believe blatantly irrational things, or why it’s reliably associated w/ mistakes like cognitive dissonance or confirmation bias. And this leads me to a wonderful new paper by Hugo Mercier & Dan Sperber that summons a wide range of evidence to argue that human reason has nothing to do with finding the truth, or locating the best alternative. Instead, it’s all about argumentation.<br />
<br />
…my new metaphor for human reason: our rational faculty isn’t a scientist – it’s a talk radio host.

"Proprioception (pronounced /ˌproʊpri.ɵˈsɛpʃən/ PRO-pree-o-SEP-shən), from Latin proprius, meaning "one's own" and perception, is the sense of the relative position of neighbouring parts of the body. Unlike the exteroceptive senses by which we perceive the outside world, and interoceptive senses, by which we perceive the pain and movement of internal organs, proprioception is a third distinct sensory modality that provides feedback solely on the status of the body internally. It is the sense that indicates whether the body is moving with required effort, as well as where the various parts of the body are located in relation to each other."

Braiiins « Snarkmarket
I've been digging into the Snarkives of posts tagged with 'braiiins' (as highlighted by @tcarmody the other day) and will probably be bookmarking some of them here (if I haven't already). Reading about neuroscience is some of the best professional development a teacher can ask for. One part that I find most fascinating is how quickly our understanding of the brain changes. And I think this gets back to the importance of uncertainty and why we should place it at the center of school programs. Science provides us with the lesson that we can update our understanding without losing face: throw out the disproved model and embrace the new, but not too tightly, rather uncertainly. That's progressive—valuing what you now know, but always moving on to something more accurate when it appears.

Alcoholism : The Frontal Cortex
"Now here's some blatant speculation. I think one reason AA is successful, at least for many of those who commit to the program, is that it's designed to force people to confront their prediction errors. Just look at the twelve steps, many of which are all about the admission of mistakes, from step number 1 ("We admitted we were powerless over alcohol--that our lives had become unmanageable") to step number 8 ("Made a list of all persons we had harmed, and became willing to make amends to them all") to step number 10 ("Continued to take personal inventory and when we were wrong promptly admitted it"). I'd suggest that the presence of these steps helps people break through the neuromodulatory problem of addiction, as the prefrontal cortex is forced to grapple with its massive failings and flaws. Because unless we accept our mistakes we will keep on making them."

"our capacity to make mistakes is utterly inextricable from what makes the human brain so swift, adaptable, & intelligent. Rather than treating errors like the bedbugs of the intellect we need to recognize that human fallibility is part & parcel of human brilliance. Neuroscientists increasingly think that inductive reasoning [IR] undergirds virtually all of human cognition. Humans use IR to learn language, organize the world into meaningful categories, & grasp relationship between cause & effect. Thanks to inductive reasoning, we are able to form nearly instantaneous beliefs & take action accordingly. However, Schulz writes, 'The distinctive thing about IR is that it generates conclusions that aren't necessarily true...probabilistically true—which means they are possibly false.' Schulz recommends that we respond to mistakes of those around us w/ empathy & generosity & demand that business & political leaders acknowledge & redress errors rather than ignoring or denying them."

Brains Of Deaf People Rewire To "Hear" Music
"Deaf people sense vibration in the part of the brain that other people use for hearing – which helps explain how deaf musicians can sense music, and how deaf people can enjoy concerts and other musical events. "These findings suggest that the experience deaf people have when ‘feeling’ music is similar to the experience other people have when hearing music. The perception of the musical vibrations by the deaf is likely every bit as real as the equivalent sounds, since they are ultimately processed in the same part of the brain," says Dr. Dean Shibata, assistant professor of radiology at the University of Washington."

Commuting : The Frontal Cortex
"David Brooks, summarizing the current state of happiness research: "The daily activity most injurious to happiness is commuting. According to one study, being married produces a psychic gain equivalent to more than $100,000 a year." In other words, the best way to make yourself happy is to have a short commute and get married. I'm afraid science can't tell us very much about marriage so let's talk about commuting. A few years ago, the Swiss economists Bruno Frey and Alois Stutzer announced the discovery of a new human foible, which they called "the commuters paradox". They found that, when people are choosing where to live, they consistently underestimate the pain of a long commute. This leads people to mistakenly believe that the big house in the exurbs will make them happier, even though it might force them to drive an additional hour to work."

"Consumers aren't always driven by careful considerations of price and expected utility. We don't look at the electric grill or box of chocolates and perform an explicit cost-benefit analysis. Instead, we outsource much of this calculation to our emotional brain, and rely on relative amounts of pleasure versus pain to tell us what to purchase. (During many of the decisions, the rational prefrontal cortex was largely a spectator, standing silently by while the NAcc and insula argued with each other.) Whichever feeling we feel most intensely tends to dictate our shopping decisions. It's like an emotional tug-of-war."

"“When people die, two parts of the brain, which usually work in opposition to each other, act cooperatively. The sympathetic nervous system—a web of nerves & neurons running through the spinal cord & spread to virtually every organ in the body—is responsible for arousal & excitement. It gets you ready for action. The parasympathetic system—with which the sympathetic system is entwined—calms you down & rejuvenates you. In life, the turning on of one system prompts the shutting down of the other. The sympathetic nervous system kicks in when a car cuts you off on the highway; the parasympathetic system is in charge as you’re falling asleep. But in the brains of people reporting mystical experiences—&, perhaps, in death—both systems are fully “on,” giving a person the sensation both of slowing down, being “out of body,” & of seeing things vividly, including memories of important people & past events."
