title: Banding of rubro-olivary terminations in the principal inferior olivary nucleus of the chimpanzee.
abstract: An electrolytic lesion centered just dorsal to, and grazing the superior surface of, the rostral red nucleus (RNr) was produced stereotactically in a single chimpanzee. Perikarya of the ipsilateral RNr exhibited retrograde cell changes, demonstrating interruption of its efferent fibers. The degenerated rubro-olivary tract was followed in silver impregnated material to the ipsilateral compact part of the pedunculopontine nucleus, pontine reticular formation and inferior olivary complex. Within the inferior olivary complex, terminations were banded and restricted to the principal subnucleus.
