[Comparative analysis of the neuronal organization of the corticocerebellar relay formations of the pons].

Under nembutal narcosis on cats, intracellular electrophysiological studies have been made of common properties and differences in the neuronal organization of the nucleus reticularis tegmenti pontis and intrinsic pontine nuclei. Reciprocal connections of all the nuclei with the cerebellum and sensorimotor cortex were revealed. It was shown that the cerebellar peduncles are involved to a different extent in the transmission of cerebellofugal signals from the nucleus reticularis tegmenti pontis and the pontine nuclei; all these nuclei have different projections to the central cerebellar nuclei and receive different descending cortical impulsation. Functionally, the investigated cortico-cerebellar pontine relay structures supplement and duplicate each other.
