Do the same subdivisions of the nucleus reticularis tegmenti pontis project onto longitudinal zones of the paramedian lobule? An anatomical study in the rabbit with retrograde tracing technique (HRP).
Rabbits were subject to iontophoretic injections of HRP into various sites of mediolateral extent of the cerebellar paramedian sublobules (PML). The distribution of retrogradely HRP-labelled neurons was mapped within the subdivisions of the pontine reticular tegmental nucleus (NRTP). Clear evidence for absence of correlation between the distribution of labelled cells within the NRTP longitudinal subdivisions and mediolateral location of HRP injection sites in PML has been obtained. The present findings suggest that there is no longitudinal compartmentalization of the NRTP-PML connectivity and the same NRTP longitudinal subdivisions project onto several sagittal zones of the PML.
