[Possible mechanisms of delay in the voluntary movement initiation].
A delay in the movement initiation was shown to entail an augmentation of the N2 wave ascending front and a delay in the ERPs P3 wave in frontal leads in healthy subjects and in parkinsonian patients. The modulation of the N2 wave seems to reflect inhibitory processes in frontal areas of the brain.
