Registration and analysis of bioelectric activity of sensory-motor cortex during the electrical stimulation of nucleus caudate in rats.

Background And Purpose: The caudate circuit takes part in cognitive control of motor activity. The purpose of the present work was registration and analysis of basic bioelectrical activity of ventral and dorsal sensory-motor cortex and nucleus caudate, study of the changes in EEG after nucleus caudate electrical stimulation and to identify of threshold level of electrical stimuli responsible for changes of electrical activity in registered brain area.

Materials And Methods: We used 28 albino Wistar rat of both genders.
