Abstract
- To study the role of subcortical structures and cerebellum nuclei in the genesis of the human brain potentials connected with motion patients were examined with parkinsonism and hyperkinetic form of children cerebral paralysis. In one group of patients the motor responses were recorded by means of long-term electrodes implanted with the medical purpose into the ventro-oral group of thalamus nuclei, subcortical nuclei and dentate cerebellum nuclei. In patients of the second group potentials, connected with motion were led from the scalp before and after one-moment destruction in the zone of the same structures. In ventro-oral and reticular thalamus nuclei lateral and medial segments of the pale globe and in the cerebellum dentate nucleus post-motor components were recorded which were considered as electrographic expression of motion realization and completion processes (P2 and N3) and also as slow negative oscillation (component N1), that pointed to participation of the studied structures not only in regulation of voluntary movement but also in the process of movement preparation. Absence of N2 component at recording motor responses from deep electrodes and its sufficient stability at scalp leads gave the reason to suggest that its genesis was connected with the cortex activity.
