New method classifies brain cells based on electrical signals

For decades, neuroscientists have relied on a technique for reading out electrical “spikes” of brain activity in live, behaving subjects that tells them very little about the types of cells they are monitoring. In a new study, researchers at the University of Tuebingen and MIT’s Picower Institute for Learning and Memory demonstrate a way to increase their insight by distinguishing […]

Deep brain stimulation eases Parkinson’s disease symptoms by boosting dopamine

In a new study of seven people with Parkinson’s disease, Johns Hopkins Medicine researchers report evidence that deep brain stimulation using electrical impulses jumpstarts the nerve cells that produce the chemical messenger dopamine to reduce tremors and muscle rigidity that are the hallmark of Parkinson’s disease, and increases feelings of well-being. “While deep brain stimulation has been used for treating […]

When does trash talking work? An expert discusses her unusual research

Karen C.P. McDermott recently completed a study on trash talk, the taunts or boasts meant to intimidate or distract an opponent. Her study was one of the first to statistically model how trash talking during a competition can influence performance. What inspired you to study trash talk? Karen C.P. McDermott: In early 2014, I watched Seattle Seahawks cornerback Richard Sherman […]
