Human cerebral potentials and visuomotor learning

Abstract

Cortical potentials during visuomotor learning were investigated in man using two hand tracking tasks: (i) direct tracking (T) and (ii) inverted (mirror) tracking (IT). Negative cerebral potentials were higher during the IT task over several cortical areas but in particular over the supplementary motor area (SMA). The acquisition of motor skill as measured in the IT task, was highly correlated with the enhancement of the negative potential. This correlation only held for the frontolateral and frontomedial cortex including the SMA but not for the other electrodes.
