[Representation of cutaneous sensitivity in the cat red nucleus].

Responses of the red nucleus neurons to the skin stimulation in unanestethized chronic cats showed most of the neurons to have wide receptive fields with areas stimulation of which caused an extremely intense and stable activation of respective neurons. The somatotopic principle of the cutaneous representation in the red nucleus was revealed. Destruction of the cerebellar nuclei and sensory motor cortex lowered the spontaneous activity of the red nucleus neurons, changed their responses to the skin stimulation, and caused the narrowing and the redistribution of the peripheral receptive fields preserving, however, the somatotopic character of the cutaneous representation in the red nucleus.
