On the caudal extension of the X zone in the cerebellar cortex of the rat.
Following a selective injection of biotinylated dextran amine in the nuclear target (the interstitial cell groups, icg) of the X zone of the rat cerebellum, retrogradely labelled Purkinje cells (PCs) were found within a longitudinal strip of cortex, 250 microns in width, 1000 microns lateral to midline. This labelling delineates two compartments in the X zone, one rostral through lobules II-VI, and one caudal through lobules VIII-X. The whole rostrocaudal extent of the icg appears to be the target of PCs from both compartments without any apparent topographical organization.
