Newly observed pre-cerebellar neurons in the rat are homologous to neurons in the nucleus conterminalis in man.
After injection of wheat germ agglutinin-horseradish peroxidase into the rat cerebellum, a small number of large neurons were labeled in a narrow area between the pyramidal tract and the inferior olivary nucleus. These labeled neurons are distinct from previously described pre-cerebellar neurons in distribution and neuronal size. Together with the known strong acetylcholinesterase activity in this area, the results of this study show that these neurons comprise a novel pre-cerebellar nucleus, which I have designated 'nucleus subolivaris'. Based upon morphological characteristics, it is likely that this small pre-cerebellar nucleus is the homologue of the nucleus conterminalis in man.
