Morphological changes of somatostatin neurons in the suprachiasmatic nucleus by hypophysectomy of the rat.

Abstract

After hypophysectomy, behavioral circadian rhythmicities in the rat became indistinct and phase shift was observed. Therefore, it was thought that the suprachiasmatic nucleus (SCN), which is the circadian oscillator in mammals, was affected by hypophysectomy. We investigated the effects of hypophysectomy on SCN neurons using immunohistochemical staining… (More)
