Vestibulo-thalamic projection to the anterior suprasylvian cortex of the cat

Suggestive evidence as to the site of a major thalamic relay of the vestibular projection to the anterior suprasylvian (ASS) cortex in the cat has been obtained using the retrograde axonal transport of horseradish peroxidase. The thalamo-cortical neurons are located in several patches surrounding the posterior margins of the ventro-basal complex (VB). This area also was found to receive vestibulo-thalamic projections. It comprises different nuclear groups known to carry somatic, acoustic, visual or combined information, which possibly have certain functions related to kinaesthesia and body orientation in common.
