title: [The activity of rubrospinal neurons in Macaca mulatta monkeys].
abstract: Action potentials of single cells in nucleus ruber have been recorded extracellularly inresponse to antidromic activation of the rubro-spinal tract and stimulation of contralateral interpositus nucleus of the cerebellum in the monkey M. mulatta. The analysis of the data obtained indicates that both large cells of the caudal portion and neurons of small-cell part of n. ruber send their axons to the spinal cord. Conduction velocity along the axons of rubro-spinal neurons in monkeys veries within 17.4--108.8 m/sec (peak velocity 60--90 m/sec). Experiments with stimulation of the interpositus nucleus of the cerebellum confirm the presence of monosynaptic interposito-rubral connections in monkeys.
