Prcto Parvis-Raw
in nervous cells during development in relation with their degree of
growth and functional maturity. We study spinal motor-cells; receptive
ganglion-cells: Purkinje's cells of cerebellum: pyramidal cells. Moreover
the cell development of the trigeminal nerve's mesencephalic nucleus and
that of spinal ganglia were studied comparatively. (Methods: Toluidine
blue or Unna-Pappenheim and ribonuclease: Piekarsky-Robinow; Feulgen:
Golgi: Cajal). Felis domestica (Carnivora)
b. Morphological and histochemical studies of histogenesis of chondroid
and mucous tissues. We study the mucous tissue of the cox-comb: the
peculiar connective tissue of the renal papilla; the tissues of the intervertebral
disk. (Aves and Mammalia)

(in collaboration with G. RONCORONI)
d. Quantitative study about the pre- and post-natal increase of cerebellar
cortex and of its different strata, with particular reference to the evolu-

e. Modifications in the histochemical characters of squamous stratified epithelia
during the development, in connection wath the modifications of the
external medium. (Amphibia, Mammalia)
