Response of the hypothalamic neurosecretory system of the female catfish, Heteropneustes fossilis (Bloch), to hypophysectomy.
The effect of hypophysectomy on the hypothalamic neurosecretory system of the catfish, H. fossilis, was studied. Hypophysectomy resulted initially in an accumulation of NSM at the distal ends of the cut axons. The axons had grown and were reorganized into a neurohypophysis-like structure 3 weeks after hypophysectomy, and this persisted even more than 3 years post-hypophysectomy.
