The anlage of the cerebellar nuclei in chick after early extirpation of the vestibular region
Diverse opinions have been advanced in the relevant literature concerning the embryological origin of the cells constituting the deep cerebellar nuclei in vertebrates. A number of different regions in the embryonic brain have in turn been regarded as the matrix region of the cerebellar nuclei; these are given below. 1. The vestibular nuclei. Dowd (1929, pig), Larsell (1935, opossum), Nistri, Fabiani & Cannizzaro (1959, man). 2. The cerebellar neural epithelium. Gentès (1906, chick), Hajashi (1924, man), Tello (1940, mouse), Baffoni (1956, cat), Baffoni & D'Ancona (1958, chick and pigeon), Baffoni (1959, toad). 3. The cerebellar neural epithelium, probably reinforced with cells from the superficial stratum granulosum, in species possessing such a cell-layer. Rüdeberg (1961, lamprey, dog-fish, pike, frog, chick, pigeon, cow and man). 4. The inner cell layer of the embryonic cerebellar cortex. Loewe (1880, rabbit [nucleus lateralis cerebelli]). Nistri & Fabiani (1956, man) traced the anlagen of the cerebellar nuclei from the neural epithelium of the cerebellum.
