...Stuart A. Tobet; David J. Zahniser; Michael J. Baum Experiments were conducted to determine when during perinatal development testicular steroids act in ferrets to promote the organization of a bilateral nucleus in a medial position at the border of the preoptic area (POA) and anterior hypothalamus...

...Michael J. Baum; Jacob A. Canick; Mary S. Erskine; Catherine A. Gallagher; John H. Shim Male ferrets born in the laboratory received subcutaneous Silastic capsules containing either the aromatase inhibitor, androst-1,4,6-triene-3, 17-dione (ATD), the 5 α-reductase inhibitor, testosterone-17β...

...B.T. Donovan; M.B. ter Haar The acute effects of hypothalamic electrical stimulation on the secretion of FSH and LH have been examined in anestrous and estrous ferrets. Basal levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were higher in the anestrous than in the estrous...

...P.A. Thorpe; J. Herbert Electrolytic lesions were made in the lateral (LTN), medial (MTN) or in both terminal nuclei of the accessory optic tract in female ferrets. Either the ipsilateral or contralateral eye was removed. Complete destruction of both nuclei, as assessed by both histological...

...) of male ferrets. The MN-POA/AH is formed only in males by the action of estradiol derived from the neural aromatization of testosterone during the last quarter of a 41-day gestation. The ferret’s dorsal POA/AH is also characterized by a sex difference in the expression of the neuropeptide galanin which...
