Abstract

The present study aims to identify the anatomic substrate locations of neural generators behind self-paced fast repetitive finger movement, by dipole analysis and cortical current density imaging from scalp-recorded movement-related potentials. Both methods demonstrated that the contralateral premotor cortex was preponderantly activated in relation to movement performance. The present results therefore suggest that premotor cortex is involved in the precise control of sequential timed movement based on the motor field (MF) of the movement related potentials. In addition, the cortical current density imaging results demonstrate increased activity in ipsilateral premotor cortex as well.
