  • Title: [Factors responsible for generation of multiple discharges in motor neurons of the nucleus of the facial nerve in cats].
    Author: Fanardzhian VV, Kasabian SA, Manvelian LR.
    Journal: Neirofiziologiia; 1981; 13(5):520-30. PubMed ID: 6272138.
    Abstract:
    Peculiarities of multiple discharges of facial nucleus motoneurons evoked to stimulation of caudal trigeminal nucleus were studied in acute experiments on cats by intracellular recording technique. The multiple discharge is shown to appear on the basis of gradual depolarization of the motoneuron membrane resulted from effective summation of high-frequency excitatory synaptic influences from the caudal trigeminal nucleus. Factors supporting the development of the gradual depolarization are dendritic location of synaptic terminals of trigeminal projecting neurons, dendritic origin of depolarizing after-potentials and high input resistance of the facial motoneuron membrane.
