[Synaptic processes in motor neurons of the nucleus of the facial nerve upon stimulation of the caudal trigeminal nucleus].

Abstract

Focal and postsynaptic potentials of facial motoneurons evoked by stimulation of the caudal trigeminal nucleus were studied in cats using extra- and intracellular recording technique. Pre- and post-synaptic components of focal potentials are shown. Four types of motoneuron responses are distinguished: EPSP generating single action potentials; gradual shift of depolarization evoking multiple discharges; rhythmical discharge of action potentials appearing at a low level of depolarization; EPSP and a sequence of EPSP-IPSP. Mono- and predominantly polysynaptic origin of these responses is shown. Possible mechanisms of afferent control of facial motoneuron activity are discussed.
