[Synaptic mechanisms of descending influences on the facial nucleus motor neurons in the cat].
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 influences onto the facial motoneurons and possible mechanisms and pathways of cortical and hypothalamic control of facial motoneurons activity are discussed.
