Fig. 19. Schematic illustration of the zonal distribution of somatostatin immunoreactive Purkinje cells at different levels of the cerebellum of a 21 day old rat. Drawings have been made from frontal, cresyl-violet stained sections. Each dot represents 2-5 cells. Abbreviations 5-9, cerebellar lobules V-IX 4V, 4th ventricle COP, copula pyramis CR2, crus 2, ansiform lobule FL, flocculus PFL, paraflocculus PM, primary fissure SF, secondary fissure. Villar et al. (1989).

Fig. 153. Diagrams showing showing the projections from the various mediolateral projection-zones of the pyramis (lobule VIII) and the copula pyramidis to the cerebellar and vestibular nuclear complexes in the rat. A. Schematic diagram of the posterior surface of the cerebellum. The subdivision of the pyramis and copula are based on the topography of their efferent projections. B. Schematic sagittal diagrams of the cerebellar and vestibular nuclei showing the terminal areas which receive projections from the individual subdivisions of pyramis and copula pyramidis. Abbreviations see Fig. 152. Umetani and Tabuchi (1988).

Fig. 185. The olivocerebellar projection to the pyramis and the uvula (lobules 8 and 9) of tbe rat cerebellum. A,B- Olivocerebellar projection zones of the lobules 8 and 9. C. Origin of these projections, indicated in diagrams of transverse sections through the inferior olive, a = subnucleus a of the medial accessory olive b = subnucleus b of the medial accessory olive beta = group beta c = subnucleus c of the medial accessory olive d = dorsal accessory olive dm = dorsomedial subnucleus m = medial accessory olive pr = principal olive 8 and 0 = lobules VIII and IX of Larsell. Relabelled and reproduced from Eisenman (1984).

Fig. 208. Diagram of the fractured somatotopy of the mossy fiber projections in the cerebellum of the rat. Patches with similar receptive fields are indicated with abbreviations for the stimulation sites on the head and the extremities. Redrawn from Welker (1987). Cr = crown El = eyelids Fbp = furry buccal pad FL = forelimb and hand G = gingiva HL = hindlimb I, II = crus I and II Li = lower incisor LI = lower lip Lob.ant. = anterior lobe lob.sim = lobulus simplex N = nose Nk = neck P = pinna PFL = paraflocculus PML = paramedian lobule PY = pyramis Rh = rhinarium Ui = upper incisor U1 = upper lip UV = uvula.
