Reward signals in the motor cortex: from biology to neurotechnology

Solaiman Shokur, Pierre Theopistos Vassiliadis

Over the past decade, research has shown that the primary motor cortex (M1), the brain's main output for movement, also responds to rewards. These reward signals may shape motor output in its final stages, influencing movement invigoration and motor learni ...
