My friend Stanford neuroscientist Melina Uncapher and her colleagues are piloting a new public project called mymntr meant to create a "user guide for your brain" through brain tests for self-knowledge, interviews with fascinating creative folks to get a sense of the minds behind the madness, and lots of other cool stuff at the intersection of science and culture.

"Those Who Are Jesus" is Steven Eastwood's fascinating 2001 documentary about three people who have true delusions of grandeur based on "profoundly religious or revalatory experiences." Read the rest
How is creativity related to schizophrenia and autism? Psychology professor Scott Barry Kaufman looks at a scientific paper suggesting that "creativity and psychosis share genetic roots" in the context of his own research on how different forms of creativity might relate to the schizophrenia spectrum and the autism spectrum.

Brandon Keim has an amazing feature up at Aeon Magazine, about the idea of animal consciousness — i.e., how animals think and feel and experience their own lives. After delving into the chimpanzee experience of death for a couple weeks, this story really grabbed my attention. Increasingly, it's an idea that scientists are paying more attention to, as well.

[Video Link] BB pal Joe Sabia points us to this incredible video by Evan Shinners, Julliard-trained pianist and "best Bach player around." In the video, Shinners shows the world the colors he sees when he plays: he has synesthesia. You can follow him on Twitter, and check him out live on one of his upcoming tour dates. Read the rest
"The distinction between neurodiverse and neurotypical is too simplistic. There is certainly a great deal of structural variability between individuals, and that's compounded by structural changes that go on across the lifespan. I'm sure [the extent of brain variability is] a lot more than most people realise." — Jon Simons, senior author on a recently published research paper looking at structural variation in the human brain, and its influence on the ability to distinguish between stuff that actually happened, and stuff we imagine. As quoted by Mo Costandi in The Guardian. Read the rest
A small Estonian study is offering some hints that our brains could be even weirder than we'd imagined. Researchers found that magnetic pulses directed at a certain part of the frontal cortex affected whether people were more willing to fib, or more likely to tell the truth. Only 16 people were involved in the study, so these results are more something potentially cool to follow up on than a definitive declaration about brain function. There's a good chance this could turn out to be a statistical fluke. But it is worth researching further. If the effect is real, it could have some really interesting ethical, legal, and neurobiological implications.
Say it with me now: "F***ing magnets, how do they work?" Mo Costandi explains:

Inga Karton and Talis Bachmann of the University of Tartu adopted a different and novel approach, by examining the natural propensity to lie spontaneously during situations in which deception has no consequences. They recruited 16 volunteers, and showed them red and blue discs, which were presented randomly on a computer screen. The participants were asked to name the colour of each disc, and that they could do so correctly or incorrectly at their free will.
The researchers used a technique called transcranial magnetic stimulation (TMS) to disrupt the participants' brain activity during the task. TMS is a non-invasive technique in which pulses of electromagnetic radiation are targeted to a specific brain region, inducing weak electrical currents that can either inhibit or enhance activity in that area.
They split the participants into two groups of eight for the experiment.
Some recent research is confirming what a lot of us have probably long suspected—there's a pretty reasonable scientific explanation for near-death experiences.
Recently, a host of studies has revealed potential underpinnings for all the elements of such experiences.
For instance, the feeling of being dead is not limited to near-death experiences—patients with Cotard or "walking corpse" syndrome hold the delusional belief that they are deceased. This disorder has occurred following trauma, such as during advanced stages of typhoid and multiple sclerosis, and has been linked with brain regions such as the parietal cortex and the prefrontal cortex—"the parietal cortex is typically involved in attentional processes, and the prefrontal cortex is involved in delusions observed in psychiatric conditions such as schizophrenia," Mobbs explains. Although the mechanism behind the syndrome remains unknown, one possible explanation is that patients are trying to make sense of the strange experiences they are having.
This story, by Charles Q. Choi, breaks down several common elements of near-death experiences the same way. But the fact that I found most interesting relates to who has "near-death" experiences. Turns out, it's not limited to people who are actually near death. Choi reports that a study of 58 patients who had had near-death experiences found that 30 of them weren't actually in danger of dying. They just thought they were. Read the rest
