Activity of neurons of the red nucleus after destruction of the inferior olive in the rat
Résumé
The spontaneous frequency of discharge of the red nucleus neurones has been evaluated in the rat before and after total and bilateral destruction of the inferior olive by 3-acetylpyridine. The suppression of the inferior olive increasing the cerebellar inhibition, produces, as a consequence, a consequence, a disfacilitation of the activity of the red nucleus neurones. The process persists for a few days, then a progressive compensation takes place. A month later the average frequency of discharge is recovered but a normal unit activity and motor behaviour are not restaured.
