title: Cortico-Darkschewitsch-olivary projection in the cat: an electron microscope study with the aid of horseradish peroxidase tracing technique.
abstract: The nucleus of Darkschewitsch (ND) of the cat was observed electron microscopically after surgical ablation of the motor cortex and horseradish peroxidase (HRP) injection into the inferior olive of the same animals. Degenerated axon terminals containing pleomorphic synaptic vesicles were observed to synapse chiefly with medium-sized or small dendritic processes, some of which were labeled with HRP retrogradely. Therefore, a cortico-olivary projection which was relayed at the ND was revealed at an ultrastructural level.
