Abstract

In anesthetized cats, we recorded intracellularly from 26 hypoglossal motoneurons which were antidromically activated following electrical stimulation of either the medial or lateral branches of the hypoglossal nerve. Twenty-one of these neurons were protruder motoneurons 6 of which had inspiratory activity. Three of the protruder motoneurons with inspiratory activity were filled with Neurobiotin and found to be closely apposed to substance P-like immunoreactive nerve terminals.
