The red nucleus activity in rats deprived of the inferior olivary complex.
The long-term effects of the inferior olive destruction on the red nucleus activity, were studied in the rat following injection of 3-acetylpyridine. As soon as the olivary activity was suppressed, the discharge of the rubral units drastically decreased. Then, they progressively recovered the control frequency during the first month, although a normal rubral activity was not restored up to 8 months. The hypothesis is advanced that the olivocerebellar system is essential to shape the activity of the rubrospinal pathway.
