[Synaptic processes in red nucleus neurons in response to stimulation of the entopeduncular nucleus and the globus pallidus of the cat].

Peculiarities of synaptic processes in red nucleus neurons evoked by stimulation of nucleus entopeduncularis and globus pallidus were studied in acute experiments on cats by means of intracellular recording technique. Stimulation of the structures mentioned was found to evoke mono- and polysynaptic excitation of the rubrospinal neurons. Analysis of time parameters of the recorded excitatory postsynaptic potentials suggested activation of axo-somatic and axo-dendritic synapses. Mechanisms of basal ganglia participation in integration of the red nucleus activity are discussed.
