Intracellular recording of potentials revealed that stimulation of cerebral cortex, gyrus proreus and pyramidal tact evoked polysynaptic excitatory and postsynaptic potentials in the cat's facial motoneurons. Stimulation of lateral hypothalamus was characterized by exclusively excitatory polysynaptic effects. High degree of convergence of the above(More)
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(More)
The antidromic activation of facial nucleus motoneurons to the stimulation of various branches of the facial nerve was studied by means of intracellular recording in cats. The time and amplitude characteristics of separate components of the antidromic spike were analyzed and fast and slow after-potentials were distinguished. A correlation was shown between(More)
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(More)
Peculiarities of the trigeminal nucleus caudalis neurons which are projected to the facial nucleus were studied by microelectrode recording in cats. It is shown that the mentioned neurons are localized predominantly in ventral parts of the trigeminal nucleus caudalis and adjacent lateral reticular formation. Mono- and polysynaptic activation of efferent(More)
