Frontal increase of beta modulation during the practice of a motor task is enhanced by visuomotor learning

Abstract Movement is accompanied by beta power changes over frontal and sensorimotor regions: a decrease during movement (event-related desynchronization, ERD), followed by an increase (event-related synchronization, ERS) after the movement end. We previously found that enhancements of beta modulati...
