Self-initiated versus externally triggered movements. I. An investigation using measurement of regional cerebral blood flow with PET and movement-related potentials in normal and Parkinson's disease subjects.

Abstract:

We investigated the functional anatomy of self-initiated and externally triggered movements. Six patients with Parkinson's disease off medication and six age-matched normals were assessed. All subjects had regional cerebral blood flow (rCBF) measurement with PET and recording of movement-related cortical potentials (MRPs) from frontal (F), fronto-central (FC), central (C) and parietal (P) sites to obtain measures of the Bereitschaftspotential (BP). The tasks were (i) self-initiated extension ...
