Role of Cerebral Cortex in Voluntary Movements
... Even slower movements may be executed largely in open loop mode once they have been thorougly learned through repetition. Preprogramming through practice and repetition may be an important process by which motor learning occurs. WHAT AREAS OF CEREBRAL CORTEX PARTICIPATE IN VOLUNTARY MOVEMENT? Areas ...
