Rat cerebellar afferents after unilateral pedunculotomy. A retrograde fluorescent double-labelling study

Abstract Cerebellar afferents from the lateral reticular nucleus (LRN) and inferior olive (IO) were investigated using retrograde fluorescent labelling in rats subjected to a unilateral inferior cerebellar pedunculotomy at 6–8 days of age. The remaining (ipsilateral) IO of the operated group was essentially the same as in control animals but the remaining (contralateral) LRN in the operated group had a greater percentage of neurones with collaterals to both sides of the cerebellum.
