[Effect of stimulation of nonspecific thalamic nuclei at different frequencies on the motor components of an instrumental defense reaction].
The high-frequency thalamic stimulation activated the motor components of instrumental defence response whereas the low--frequency stimulation suppressed them. Lesion of the thalamic center median does not alter criteria of the response but sharply increases thresholds of the current applied to the caudate nucleus head for obtaining the "caudate arrest". The data suggest an important role of the afferent projections from the thalamic intralaminar nuclei to the caudate nucleus in triggering the strial inhibitory control over behaviour in animals.
