Role of Premotor Cortex in Programming and Execution of Movements

Abstract

Recent neurophysiological as well as neuropsychological studies provided several hypotheses on how motor programs are generated in the central nervous system. Amajor conclusion emerged from neurophysiological studies on the premotor cortex (PM)of monkeys that each of movement parameters such as amplitude and direction is distinctively programmed in the PM by serial integration, rather than by parallel distributed processing.
