| Abstract: | Synaptic processes in red nucleus neurons produced by stimulating the entoped-uncular nucleus and the globus pallidus were investigated during acute experiments on cats using intracellular recording techniques. It was found that stimulating these structures produces mono- and polysynaptic excitation of rubrospinal neurons. Analysis of the time parameters of the EPSP recordings obtained suggested that they were produced by activation of the axosomatic and axodendritic synapses of rubrospinal neurons. Mechanisms of basal ganglia involvement in the integrating of red nucleus activity are examined.L. A. Orbeli Institute of Physiology, Academy of Sciences of the Armenian SSR, Erevan.
