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)
Synaptic processes induced in the facial motoneurons by stimulation of the red nucleus and the cerebellar interpositus and dentate nuclei were studied in anesthetized and immobilized cats. The stimulation of the red nucleus evoked monosynaptic EPSPs in the motoneurons whereas oligo--and polysynaptic EPSPs were recorded in response to the stimulation of the(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)
Synaptic inputs from the midbrain and medulla oblongata to the facial motoneurones were studied in anesthetized cats in acute experiments: the effects of stimulation of the n. reticularis parvocellularis, the interstitial nucleus of Cajal and the nucleus of Darkschewitsch. Stimulation of these nuclei evoked monosynaptic excitatory postsynaptic potentials in(More)
Peculiarities of synaptic processes in motoneurons of the facial nucleus evoked by stimulation of the head of caudate nucleus, globus pallidus and nucleus amygdalae centralis were studied in acute experiments on cats by means of intracellular recording technique. It is found that stimulation of the first two structures causes only polysynaptic excitation,(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)
