Abstract

The connection between the activity of the gonadotropic cells of the hypophysis and the neurosecretion in the pre-optico neuro-hypophysial system in different groups of vertebrates has been examined by many authors. It has been established that in many species there exists some kind of synchronism between the sexual cycle and the cellular activity of neurosecretion, a fact that has led to the prevailing idea that gonadotropic activity in the hypophysis is regulated by the hypothalamus. This paper summarises the results of experiments made in this direction on Cyclostomata. The materials for research came from adult individuals of Eudontomyson danfordi Regan taken from the rivers Somes-Rece and Ivo (Harghita district) at different times of the year.
