The normal anatomy of the cerebellum has been thoroughly studied by numerous in vestigators over many years. Anatomical aspects in terms of evolution (Dow, 1942; Larsell, 1967; Llinas, 1969; Gregory, 1975), correlative anatomy (Wallenberg, 1931), and morphology (Larsell, 1952; L0ning and Jansen, 1955; Ludwig-Hauri, 1955; Braitenberg and Atwood, 1958; Jansen und Brodal, 1958; Zeman and Innes, 1963) have been presented. Histological features have attracted many investigators (Bergmann, 1857; Denis senko, 1877; Ramon y Cajal and Illera, 1907; Addison, 1911; Jakob, 1928; Snider and Jacobs, 1949; Braitenberg and Atwood, 1958; Baud, 1959; Altman, 1962, 1963, 1966, 1971, 1972a, b, c, 1973a, b, 1975; Birch-Anderson et aI. , 1962; Andres, 1965; Eccles et aI. , 1967; Fox and Snider, 1967; Mugnaini and Forstrl1. lDen, 1967; Del Cerro and Snider, 1968, 1972a, b; O'Leary et aI. , 1968, 1971; Chan-Palay and Palay, 1970, 1971, 1972; Rakic and Sidman, 1970; Das and Altman, 1971; Gobel, 1971; Rakic, 1971; 1972a, b; Chan-Palay, 1972a, b, 1973c, d; Palay and Chan-Palay, 1972, 1974; Sidman and Rakic, 1973; Spacek et aI. , 1973; Das et al. , 1974; Braak, 1975; Crepel and Mariani, 1975; Derrnietzel, 1975a, b; Gregory, 1975; Llinas, 1975; Meller and Tetzlaff, 1975; Cragg, 1976; Rees et aI. , 1976; Zelevic and Rakic, 1976). Investigators of the cytologi cal characteristics of the cerebellar cortex are numerous (Sternberg and Krombholtz, 1838; Smirnow, 1897; Ramon y Fananas, 1916; Larramendi et al.
