Localization of masticatory motoneurons in the cat and rat by means of retrograde axonal transport of horseradish peroxidase

Abstract

Topographical localization of motoneurons supplying the masticatory muscles was investigated in the cat and rat, utilizing retrograde axonal transport of horseradish peroxidase. Following injection of horseradish peroxidase in each masticatory muscle, motoneurons labelled with peroxidase were seen to be aggregated into a cluster within the motor nucleus of the trigeminal nerve. Such clusters of peroxidase‐labelled motoneurons innervating each masticatory muscle were demarcated more sharply in kittens than in adult animals. The pattern of the nuclear representation of the masticatory muscles was found to be essentially the same in the cat and rat; it could be summarized as follows:
