[Electrical responses of the red nucleus to acoustic stimulation].

Letency of evoked potentials (EPs) recorded in the anesthetized cat's magnocellular part of red nucleus varied from 3.5 to 4.5 msec on binuaural and contralateral stimulations. In ipsilateral stimulation, latency of EPs varied from 6 to 10.5 msec. EPs of the parvocellular part of the red nucleus were of two types: EP of the first type had latency of 4-5 msec, of the second type -6.5-10.5 msec on binaural and contralateral stimulations. In ipsilateral stimulation EP of the first type occurred with latency of 6-9 msec, those of the second -8.5-14 msec. Both latency and amplitude of the responses depended on intensity of the auditory stimulation. Possible ways of transmission of auditory information to red nucleus are discussed.
