title: [Synaptic processes in red nucleus neurons induced in the cat by stimulation of the substantia nigra].
abstract: Peculiarities of synaptic processes in red nucleus neurons evoked by stimulation of various parts of substantia nigra and cerebellar interposital nucleus were studied in acute experiments in cats using an intracellular recording technique. Such stimulation is stated to induce mono- and polysynaptic activation of the rubrospinal neurons. Great similarity is found in developing monosynaptic cerebellar and nigral excitatory effects. Convergence of these influences onto the same rubro-spinal neurons is revealed. Functional significance of inputs from substantia nigra to the red nucleus for performance of movements is discussed.
