Olivary projection from the rostral part of the nucleus of Darkschewitsch in the postnatal rat as revealed through the use of a carbocyanine dye

Abstract

Using a carbocyanine dye in postnatal rats, we have shown that the rostral part of the nucleus of Darkschewitsch (ND), consisting of a subnucleus of the so-called "area parafascicularlis prerubralis " and excluded from the rat's ND proper, projects ipsilaterally to the rostral part of the medial accessory olive. The present study suggests the existence of a precise topographic organization from subnuclei of the area parafascicularlis prerublaris to subnuclei of the inferior olive.
