Cortical sensorimotor activity in the execution and suppression of discrete and rhythmic movements

Abstract Although the engagement of sensorimotor cortices in movement is well documented, the functional relevance of brain activity patterns remains ambiguous. Especially, the cortical engagement specific to the pre-, within-, and post-movement periods is poorly understood. The present study addres...
