Carl Schoonover and Andrew Fink are confused. As neuroscientists, they know that the brain must be flexible but not too flexible. It must rewire itself in the face of new experiences, but must also consistently represent the features of the external world. How? The relatively simple explanation found in neuroscience textbooks is that specific groups of neurons reliably fire when their owner smells a rose, sees a sunset, or hears a bell. These representations—these patterns of neural firing—presumably stay the same from one moment to the next. But as Schoonover, Fink, and others have found, they sometimes don’t. They change—and
With thousands of young Black and brown Milwaukeeans migrating every year to larger cities including Atlanta, Washington D.C. and Houston, a group of young professionals has come up with recommendations to keep their colleagues from leaving.
Milwaukee’s Millennial Task Force has spent the last year studying the city’s so-called brain drain. The group presented their findings and recommendations early this month to the Milwaukee Common Council’s Community and Economic Development Committee.
“While Milwaukee has comparatively low cost of living and opportunities for entrepreneurship, the high rates of poverty, insufficient educational systems, segregation, limited cultural scenes and concerns about public safety
Electrodes in a paralyzed man’s brain turned his imagined handwriting into words typed on a screen. The translation from brain to text may ultimately point to ways to help people with disabilities like paralysis communicate using just their thoughts.
A 65-year-old man had two grids of tiny electrodes implanted on the surface of his brain. The electrodes read electrical activity in the part of the brain that controls hand and finger movements. Although the man was paralyzed from the neck down, he imagined writing letters softly with his hand. With an algorithm, researchers then figured out the neural patterns that
