☆ This is a healthy brain on psilocybin

It wasn’t until his brain morphed into a computer, however, that he knew for sure he was on a psychedelic trip. “We found that psilocybin desynchronizes the brain,” said co-senior author Ginger Nichols of the study published Wednesday in the journal Nature. “When psilocybin is on board, the brain is disconnecting from its typical pathways and reconnecting to different parts of the brain,” said Nichols, an associate professor of psychiatry at Washington University School of Medicine in St. Louis. “Science doesn’t fully understand the brain yet, but I felt as if I suddenly knew exactly how the brain works. Sara Moser/Washington University School of MedicineA window for changeScans showed that in the days after the psilocybin trip, most brain networks returned to normal.

☆ This Is Literally Your Brain on Drugs

The image, as it happens, comes from dozens of brain scans produced by researchers at Washington University School of Medicine in St. Louis who gave psilocybin, the compound in “magic mushrooms,” to participants in a study before sending them into a functional M.R.I. The kaleidoscopic whirl of colors they recorded is essentially a heat map of brain changes, with the red, orange and yellow hues reflecting a significant departure from normal activity patterns. The blues and greens reflect normal brain activity that occurs in the so-called functional networks, the neural communication pathways that connect different regions of the brain. The scans, published Wednesday in the journal Nature, offer a rare glimpse into the wild neural storm associated with mind-altering drugs. “Psilocybin, in contrast to any other drug we’ve tested, has this massive effect on the whole brain that was pretty unexpected,” said Dr. Nico Dosenbach, a professor of neurology at Washington University and a senior author of the study.

☆ Scientists identify mind-body nexus in human brain

The researchers called this system the somato-cognitive action network, or SCAN, and documented its connections to brain regions known to help set goals and plan actions. "Basically, we now have shown that the human motor system is not unitary. A second system, the SCAN, is more important for integrated, whole body movements, and is more connected to high-level planning regions of your brain," Gordon said. I'm not a philosopher, but one succinct statement I like is saying, 'The mind is what the brain does.' "Some neuroscientists think of the brain as an organ intended primarily to perceive and interpret the world around us.
