Summary
Combined injections of 3H-leucine and HRP were made into the monkey cerebellar cortex in order to identify any reciprocal connections between the corticonuclear and the nucleocortical pathways. These combined intraaxonal labeling experiments have demonstrated a considerable overlap of orthogradely labeled Purkinje cell axons and terminals with retrogradely labeled HRP-positive neurons in the ventrolateral region of the dentate nucleus following combined injections into the lateral hemisphere, and in the dorsal area of the dentate following combined injections into medial cortical areas of the anterior lobe. There were also areas within the deep cerebellar nuclei where orthogradely labeled corticonuclear terminals did not overlap with retrogradely labeled nucleocortical neurons.
