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 […]
