Cerebellar Autonomic Function: Direct Hypothalamocerebellar Pathway

Abstract

A direct hypothalamocerebellar projection in the cat was revealed by means of retrograde transport of wheat germ agglutinin--horseradish peroxidase complex. This appears to be the first demonstration of a significant autonomic input to the cerebellum. The projection has a widespread origin and is bilateral with an ipsilateral preponderance.
