Out-of-body experience: Master of illusion:
Out-of-body experiences are just part of Ehrsson's repertoire. He has convinced people that they have swapped bodies with another person, gained a third arm, shrunk to the size of a doll or grown to giant proportions.
[ . . . ]
But Ehrsson's unorthodox apparatus amount to more than cheap trickery. They are part of his quest to understand how people come to experience a sense of self, located within their own bodies. The feeling of body ownership is so ingrained that few people ever think about it — and those scientists and philosophers who do have assumed that it was unassailable.
[ . . . ]
Ehrsson's work also intrigues neuroscientists and philosophers because it turns a slippery, metaphysical construct — the self — into something that scientists can dissect.

Are you tired of reading about how neuroscientists have discovered the area of the brain devoted to a single, oddly-specific function, but lack access to the sophisticated neuroimaging technologies needed to refute them?
NeuroSynth has you covered.

The Brain on Trial. Advances in brain science are calling into question the volition behind many criminal acts. A leading neuroscientist describes how the foundations of our criminal-justice system are beginning to crumble, and proposes a new way forward for law and order.
"We may someday find that many types of bad behavior have a basic biological explanation—as has happened with schizophrenia, epilepsy, depression, and mania."

"In the Bible, God appeared to Ezekiel as a “wheel within a wheel”. Spirals and concentric circles are commonly found in petrogylphs carved by cultures long dead. Similar visual effects are reported during extreme psychological stress, fever delirium, psychotic episodes, sensory deprivation, and are reliably induced by psychedelic drugs."

Rise of the Neuronovel. Marco Roth at N+1 argues that the recent interest of contemporary novels (
Motherless Brooklyn,
Saturday,
Atmospheric Disturbances) in the disordered wetware of their characters represents a defeat for fiction. "...the new genre of the neuronovel, which looks on the face of it to expand the writ of literature, appears as another sign of the novel’s diminishing purview."
Jonah Lehrer responds to Roth and Roth responds back.

A Real Science of Mind Neurobabble piques interest in science, but obscures how science works. Individuals see, know, and want to make love. Brains don’t. Those things are psychological — not, in any evident way, neural.

An idle brain may be the self's workshop. 'Recent research suggests that mind-wandering may be important and that knowledge of how it works might help treat such conditions as Alzheimer's disease, autism, depression and schizophrenia.' Once upon a time, scientists didn't regard idle musings of the wandering mind as very important. 'But in the span of a few short years, they have instead come to view mental leisure as important, purposeful work — work that relies on a powerful and far-flung network of brain cells firing in unison. Neuroscientists call it the "default mode network."''Understanding that setting may do more than lend respectability to the universal practice of zoning out: It may one day help diagnose and treat psychiatric conditions as diverse as
Alzheimer's disease,
autism,
depression and
schizophrenia — all of which disrupt operations in the default mode network. Beyond that lies an even loftier promise. As neuroscientists study the idle brain, some believe they are exploring a central mystery in human psychology: where and how our concept of "self" is created, maintained, altered and renewed.'

Oliver Sacks is surviving cancer of the eye, ocular melanoma. In his latest book,
The Mind’s Eye, he "tells the stories of people who are able to navigate the world and communicate with others despite losing what many of us consider indispensable senses and abilities." In the interview, Sacks talks about his diagnosis, the after-effects of his radiation treatment (which include hallucinations that resolve themselves into words if he "smokes a little pot"), his apprenticeships with poets W.H. Auden and Thom Gunn, and the importance of science writing in an age when the authority of science is being undermined by religious zealots. Via MeFi's own, Steve Silberman, digaman.

The Lucretian swerve: The biological basis of human behavior and the criminal justice systemAs de Duve has written, “If … neuronal events in the brain determine behavior, irrespective of whether they are conscious or unconscious, it is hard to find room for free will. But if free will does not exist, there can be no responsibility, and the structure of human societies must be revised”.
Ben Libet & free will, previously on metafilter. (And more on: Lucretius, Dualism, Philosophy of mind, and Free Will 1, 2.)

Optimizing Your Brain at Work is a pretty fascinating talk at Google by David Rock about managing your brain's internal states and attention, as well as threat responses with the goal of optimizing information processing. It is a Youtube link, and fairly long (~55min). He also mentions
The Neuroscience of Mindfulness during the talk, so here is a convenient link to that.
