[Rhythmic afterdischarge in the cortical and subcortical structures of the cat in response to stimulation of the claustrum].
Effects of the claustrum and caudate nucleus stimulation in the neocortex and different subcortical structures were studied in unanesthetized tubarine-immobilized cats. Rhythmic afterdischarges were evoked in the neocortical regions 4-7 and 18 (according to the Reinoso-Suarez atlas) as well as in the caudate nucleus and in different regions of the thalamus. A similar rhythmic afterdischarge was observed in the claustrum itself. Diencephalic section of the brain at the level of the ventral anterior nucleus weakened but did not entirely eliminate rhythmic afterdischarge induced by stimulation of the claustrum in the anterior parts of the neocortex. Rhythmic afterdischarge was completely blocked after a sagittal section of the brain between the claustrum and the rest of the thalamus.
