Abstrakt: Properties of neurons of the trigeminal nucleus caudalis, with projections into the facial nucleus, were investigated in cats by a microelectrode technique. These neurons were found to be located mainly in the ventral parts of the trigeminal nucleus caudalis and in the adjacent lateral reticular formation. Monosynaptic and polysynaptic activation of efferent neurons of the trigeminal nucleus caudalis was found in response to pyramidal impulsation. Repeated discharges were recorded in the test neurons in response to stimulation of their axons, to direct stimulation of the trigeminal nucleus caudalis, and also to stimulation of the pyramidal tract and facial nerve. The synaptic mechanisms of regulation of motoneuron activity in the facial nerve nucleus are discussed. [ABSTRACT FROM AUTHOR]
