Information processes in the motor system: approach with transcranial magnetic stimulation

Reaching with the hand into space is used to grasp a target in order to handle it. It necessitates information about spatial position of the target and the hand that has to be converted into motor command. Beside others, neuronal mechanisms of the parietal and several frontal motor cortical areas are involved. Accuracy and speed of responding (reaction time) are commonly evaluated for quantification of subject's performance but also as a measure of movement preparation and programming. The present work focuses on methodological aspects of a reaching paradigm and introduces transcranial magnetic stimulation (TMS)…
