See-through brains clarify connections : Nature News & Comment
"A chemical treatment that turns whole organs transparent offers a big boost to the field of ‘connectomics’ — the push to map the brain’s fiendishly complicated wiring. Scientists could use the technique to view large networks of neurons with unprecedented ease and accuracy. The technology also opens up new research avenues for old brains that were saved from patients and healthy donors."

Seeing God in the Third Millennium - Oliver Sacks - The Atlantic
"Hallucinations, whether revelatory or banal, are not of supernatural origin; they are part of the normal range of human consciousness and experience. This is not to say that they cannot play a part in the spiritual life, or have great meaning for an individual. Yet while it is understandable that one might attribute value, ground beliefs, or construct narratives from them, hallucinations cannot provide evidence for the existence of any metaphysical beings or places. They provide evidence only of the brain's power to create them."

How Your Cat Is Making You Crazy - Magazine - The Atlantic
"Jaroslav Flegr is no kook. And yet, for years, he suspected his mind had been taken over by parasites that had invaded his brain. So the prolific biologist took his science-fiction hunch into the lab. What he’s now discovering will startle you. Could tiny organisms carried by house cats be creeping into our brains, causing everything from car wrecks to schizophrenia? A biologist’s science- fiction hunch is gaining credence and shaping the emerging science of mind- controlling parasites."

PLoS ONE: Microstructure Abnormalities in Adolescents with Internet Addiction Disorder
Recent studies suggest that internet addiction disorder (IAD) is associated with structural abnormalities in brain gray matter. However, few studies have investigated the effects of internet addiction on the microstructural integrity of major neuronal fiber pathways, and almost no studies have assessed the microstructural changes with the duration of internet addiction.

High Wired: Does Addictive Internet Use Restructure the Brain?: Scientific American
Kids spend an increasing fraction of their formative years online, and it is a habit they dutifully carry into adulthood. Under the right circumstances, however, a love affair with the Internet may spiral out of control and even become an addiction.

Whereas descriptions of online addiction are controversial at best among researchers, a new study cuts through much of the debate and hints that excessive time online can physically rewire a brain.

News: 'Now You See It' - Inside Higher Ed
Cathy N. Davidson, author of the forthcoming book Now You See It: How the Brain Science of Attention Will Transform the Way We Live, Work, and Learn (Viking) could safely be deemed a Never-Better, with perhaps a dash of the Ever-Waser. The major technological changes of the past decade and a half present an array of "exciting opportunities," Davidson argues -- opportunities to promote efficiency, satisfaction and success at every stage from kindergarten through career. If we are inclined to side with the Better-Nevers, worrying that our brains never evolved for shifts of such magnitude -- if kids attend to text messages and video games with alacrity, but fall behind in school, while adults feel swamped by information overload and spread too thin by multitasking -- the trouble, in Davidson's view, is not with all our new technologies, but rather with our failure thus far to adapt and restructure ourselves and our institutions.

Human Brain Limits Twitter Friends To 150 - Technology Review
"It turns out that when people start tweeting, their number of friends increases until they become overwhelmed. Beyond that saturation point, the conversations with less important contacts start to become less frequent and the tweeters begin to concentrate on the people they have the strongest links with.

So what is the saturation point? Or, in other words, how many people can tweeters maintain contact with before they get overwhelmed? The answer is between 100 and 200, just as Dunbar predicts. "

A Real Science of Mind -
"In recent years popular science writing has bombarded us with titillating reports of discoveries of the brain’s psychological prowess. Such reports invade even introductory patter in biology and psychology. We are told that the brain — or some area of it sees, decides, reasons, knows, emotes, is altruistic/egotistical, or wants to make love. For example, a recent article reports a researcher’s “looking at love, quite literally, with the aid of an MRI machine.” One wonders whether lovemaking is to occur between two brains, or between a brain and a human being.

There are three things wrong with this talk."

We agree it’s WEIRD, but is it WEIRD enough? « Neuroanthropology
The most recent edition of Behavioral and Brain Sciences carries a remarkable review article by Joseph Henrich, Steven J. Heine and Ara Norenzayan, ‘The weirdest people in the world?’ The article outlines two central propositions; first, that most behavioural science theory is built upon research that examines intensely a narrow sample of human variation (disproportionately US university undergraduates who are, as the authors write, Western, Educated, Industrialized, Rich, and Democratic, or ‘WEIRD’).

More controversially, the authors go on to argue that, where there is robust cross-cultural research, WEIRD subjects tend to be outliers on a range of measurable traits that do vary, including visual perception, sense of fairness, cooperation, spatial reasoning, and a host of other basic psychological traits. They don’t ignore universals – discussing them in several places – but they do highlight human variation and its implications for psychological theory.

Henry Molaison Brain - Jacopo Annese Brain Study - Esquire
When a surgeon cut into Henry Molaison's skull to treat him for epilepsy, he inadvertently created the most important brain-research subject of our time — a man who could no longer remember, who taught us everything we know about memory. Six decades later, another daring researcher is cutting into Henry's brain. Another revolution in brain science is about to begin.

You Are What You Touch: How Tool Use Changes the Brain's Representations of the Body: Scientific American
These results elegantly confirm that the human brain maintains a highly flexible representation of the body, despite the tendency in everyday life to think of ourselves as having a fixed personal identity, linked to our body. Two distinctive features of mental body representation emerge. First, from the brain’s perspective, the body is by far the most familiar object in the world: the body, as William James elegantly put it, is “always there.” In these experiments, the mechanical gripper could be treated as part of one’s own body...

Second, these studies suggest a view of the body as an interface between the brain and the external world. This view has important implications for human psychology generally.

Dopaminergic Aesthetics : The Frontal Cortex
The purpose of pleasure, then, is to make it easier for the pleasurable sensation - the delicious taste, the elegant idea, the desired object - to enter the crowded theater of consciousness, so that we'll go out and get it. That's why we've got a highway of nerves connecting the parts of the dopamine reward pathway - the nucleus accumbens, ventral striatum, etc - to the prefrontal cortex. (This also means that a well-turned phrase or pretty painting will be more likely to get stuck in working memory, since it's more rewarding. Aesthetics are really about attention.)

Religious Experience Linked to Brain’s Social Regions | Wired Science |
In a study published Monday in Public Library of Science ONE, Grafman’s team used an MRI to measure the brains areas in 40 people of varying degrees of religious belief.

People who reported an intimate experience of God, engaged in religious behavior or feared God, tended to have larger-than-average brain regions devoted to empathy, symbolic communication and emotional regulation

Should Creative Workers Use Cognitive-Enhancing Drugs? | Open The Future | Fast Company
For those of you who haven't been watching this trend, the dilemma is that certain pharmaceuticals intended to treat cognitive and neurological disorders--primarily, attention deficit/hyperactivity disorder and narcolepsy--and, when used by people without these disorders, provide a kind of cognitive boost. This usually means increased focus and concentration, but it can also mean better spatial reasoning, greater alertness, and improved "clarity" of thinking. As a result, it's apparently becoming increasingly common for people in "knowledge work" professions to take these drugs as a way of improving their performance.

Social Networking and the Brain: Continuous Partial Empathy? | Open The Future | Fast Company
For more than a decade, tech pundits and business consultants have gone on about the "attention economy," arguing that attention has economic value due to its limited availability. It strikes me that this may miss the greater point. From a social perspective, what's limited isn't attention, but consideration. Not just hearing, but listening. Not just seeing a message, but understanding its meaning.

Finding Connections: How Do the Parts of the Brain Interact?: Scientific American
As our understanding of the brain has improved, however, it has become clear that a more accurate model depends on how these modules are wired together in circuits. A technique called diffusion tensor imaging (DTI) gives us a tool to probe the nature of those connections. A recent study suggests, for instance, that the more a person seeks out new experiences and relies on social approval, the stronger his or her wiring is among brain areas involved in reward, emotion and decision making.

Brain immediately recognizes transplanted hand : Neurophilosophy
This study shows that the reorganizational changes which occur following amputation are reversible. 35 years after Savage lost his hand, the organization of his somatosensory cortex returned to a state that is indistinguishable from what would have been expected in before the amputation, even though the functional reorganization would have increased with time.

How the city hurts your brain -
The reason such seemingly trivial mental tasks leave us depleted is that they exploit one of the crucial weak spots of the brain. A city is so overstuffed with stimuli that we need to constantly redirect our attention so that we aren't distracted by irrelevant things, like a flashing neon sign or the cellphone conversation of a nearby passenger on the bus. This sort of controlled perception -- we are telling the mind what to pay attention to -- takes energy and effort. The mind is like a powerful supercomputer, but the act of paying attention consumes much of its processing power.

How to Run a Con | Psychology Today Blogs
The key to a con is not that you trust the conman, but that he shows he trusts you. Conmen ply their trade by appearing fragile or needing help, by seeming vulnerable. Because of THOMAS, the human brain makes us feel good when we help others--this is the basis for attachment to family and friends and cooperation with strangers. "I need your help" is a potent stimulus for action.
