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

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.
