[Vestibulofugal projections to the lateral reticular nucleus of the cat medulla]

Abstract

Certain amount of neurons in vestibular nuclei were labelled after horseradish peroxidase injection in the medullar lateral reticular nucleus of cat. Such projections were strictly homolateral and formed by small and medium-size neurons localized mainly in the Deiters nucleus; their number was, probably, much less in comparison with the number of vestibulo-spinal units. Functional role of vestibular projections to the lateral reticular nucleus in the motor activity control is discussed.
