Abstract
It could be demonstrated that the embryonic cells in the subcommissural organ, in the dorsal sac and in the paraphysis of Anguis fragilis and Chalcides ocellatus are identical with those which, in the parietal eye and in the epiphysis, form the primary cells of sense organs. The undifferentiated sensory cells could also be found in the stalk of the epiphysis of Natrix natrix. The identical histogenesis of the cells was interpreted according to the "ependyme-senseorgan" theory. A pair of the primordia of the subcommissural organ develop in the dorsal diencephalon.Keywords
