In a significant departure from earlier models, neural engineers and neuroscientists have developed a new model for the brain activity underlying arm movements. Motor neurons do not represent external ...

When a fruit fly gets dust on its body, it launches into a precise cleaning routine, sweeping and rubbing its legs in rhythmic strokes that look almost mechanical. Scientists have long assumed that ...

Even if you can't keep a beat, your brain can. "The brain absolutely has rhythm," says Nathan Urban, a neuroscientist at Carnegie Mellon University in Pittsburgh. When you concentrate, Urban says, ...

Unlike their visual cousins, the neurons that control movement are not a predictable bunch. Scientists working to decode how such neurons convey information to muscles have been stymied when trying to ...
