Intracellular recordings were made from trigeminal motoneurons of normally respiring, unanesthetized cats during naturally occurring sleep. The transition quiet to active sleep was accompanied by tonic motoneuron hyperpolarization. Stimulation the reticular formation induced a depolarizing potential in and hyperpolarizing results provide synaptic explanation for phenomenon response reversal insights into basic mechanisms controlling motor activity states.
