There are two important nuclei and one area in the hypothalamus that send out the neural autonomic information to the peripheral organs: the ventromedial hypothalamic nucleus (VMH) in the medial area, the lateral hypothalamic area (LHA), and the periventricular hypothalamic nucleus (PVN) in the periventricular area. WebAbstract. Kisspeptins, derived from the Kiss1 gene play a central role in activation of the hypothalamo-pituitary gonadal (HPG) axis via stimulation of GnRH neurons. Both Kiss1 and Kiss1R (receptor) mRNA levels are found to be low in pre-pubertal rats, but whether an increase in kisspeptin and/or its receptor is the primary component in the ...

Confocal images of double-labeled zebrafish Tac1 and GnRH3 showed associations between Tac1-immunoreactive processes and GnRH3 neurons in the ventral telencephalic area. The periventricular nucleus is a thin sheet of small neurons located in the wall of the third ventricle, a composite structure of the hypothalamus. It functions in analgesia. It is located in the rostral, intermediate, and caudal regions of the hypothalamus. The rostral region aids in the production of both somatostatin and thyroid releasing hormone.
