Popis:	BILATERAL removal of the sphenopalatine ganglion, in the rat, is followed by pseudopregnancy in 40 per cent of the cases (1). This result suggested a pos-sible neural effect upon the gonadotropic function of the hypophysis. In-vestigation of the proximal nerve supply to the sphenopalatine ganglion disclosed (2) at the junction of the greater superficial petrosal nerve with the great deep petrosal nerve a small ganglion, the Vidian ganglion, from which small branches are distributed to the sixth nerve, to the internal carotid plexus, and to the sheath and probably the parenchyma of the anterior lobe of the hypophysis. The present study is concerned with the Vidian ganglion as a possible source of innervation to the an-terior lobe, and with the physiological effects on the hypophysis of Vidian gan-glionectomy. Two aspects of hypophyseal function have been selected for study in animals in which the Vidian ganglia have been extirpated, a) the gonadotropic factor, with the production of pseudopregnancy as a cr...
