Psilocybin generates psychedelic experience by disrupting brain network

People who consume psilocybin-containing mushrooms — otherwise known as magic mushrooms — typically undergo a surreal experience in which their sense of space, time and self is distorted. Advocates have long argued that, under the right conditions, psychedelic experiences can alleviate mental distress, and a smattering of scientific studies suggests they may be right. Understanding […]

Mind-body connection is built into brain, study suggests

Calm body, calm mind, say the practitioners of mindfulness. A new study by researchers at Washington University School of Medicine in St. Louis indicates that the idea that the body and mind are inextricably intertwined is more than just an abstraction. The study shows that parts of the brain area that control movement are plugged […]

For accuracy, brain studies of complex behavior require thousands of people

As brain scans have become more detailed and informative in recent decades, neuroimaging has seemed to promise a way for doctors and scientists to “see” what’s going wrong inside the brains of people with mental illnesses or neurological conditions. Such imaging has revealed correlations between brain anatomy or function and illness, suggesting potential new ways […]

Changing how we see the brain

His phone rang all day. Same unknown number. It had to be a telemarketer. Engrossed in an NIH workshop about the obstacles of research, Damien Fair, PhD ’08, ignored the call. At the end of the day, he answered to say, in his polite Minnesota-bred way, “Please take me off your list!” A weighted pause. […]

Brain rewires itself after injury ‘on the edge of what’s compatible with life’

For 13 years, Daniel Carr had no idea he was missing part of his brain. One of the first clues occurred on the baseball field. The coach of his seventh-grade boys’ competitive team in suburban St. Louis noticed Daniel’s unusual, albeit effective, fielding tactic in the outfield. Daniel wore his glove on his right hand. […]

Board of Trustees grants faculty appointments, promotions

At the Washington University in St. Louis Board of Trustees meeting Oct. 2, several faculty members were appointed or promoted with tenure or granted tenure, effective that day unless otherwise indicated… …Promotion with tenure Luis F.Z. Batista to associate professor of medicine and of developmental biology at the School of Medicine (tenure effective Jan. 1); Nico […]

Previously undetected brain pulses may help circuits survive disuse, injury

A neuroscientist’s neon pink arm cast led him and fellow researchers at Washington University School of Medicine in St. Louis to discover previously undetected neuronal pulses in the human brain that activate after an immobilizing illness or injury. The pulses appeared on MRI scans used to measure brain activity of the neuroscientist and, later, two […]

Why doesn’t deep-brain stimulation work for everyone?

People with severe Parkinson’s disease or other neurological conditions that cause intractable symptoms such as uncontrollable shaking, muscle spasms, seizures, obsessive thoughts and compulsive behaviors are sometimes treated with electric stimulators placed inside the brain. Such stimulators are designed to interrupt aberrant signaling that causes the debilitating symptoms. The therapy, deep-brain stimulation, can provide relief […]

Wearable motion detectors identify subtle motor deficits in children

A wristwatch-like motion-tracking device can detect movement problems in children whose impairments may be overlooked by doctors and parents, according to a new study from Washington University School of Medicine in St. Louis. The findings, published April 26 in JAMA Network Open, could help identify children with subtle motor impairments so they can be treated […]

The Underestimated Cerebellum Gains New Respect From Brain Scientists

From NPR (heard on All Things Considered)… An ancient part of the brain long ignored by the scientific world appears to play a critical role in everything from language and emotions to daily planning. It’s the cerebellum, which is found in fish and lizards as well as people. But in the human brain, this structure […]

Mind’s quality control center found in long-ignored brain area

From the WashU Newsroom… The cerebellum can’t get no respect. Located inconveniently on the underside of the brain and initially thought to be limited to controlling movement, the cerebellum has long been treated like an afterthought by researchers studying higher brain functions. But researchers at Washington University School of Medicine in St. Louis say overlooking […]
