As a male neurologist, I can tell you that less than 0.25% of brain mass is sexually dimorphic hypothalamic preoptic area, ventromedial nucleus and supraoptic area and that is hypothalamic, related, so far as we know, to chemical and hormonal regulation. ❋ Unknown (2005)

This led him to an early awareness of the dynamic nature of the interrelationship between glial cells in the supraoptic nucleus and the neurones, and between the glial cells (pituicytes) in the posterior pituitary and the neurosecretory nerve endings there; two classic papers published with Charles Tweedle in in 1976 and 1977, showed clearly using electron microscopy that the anatomical relationships of these elements was not fixed but dynamically regulated in different physiological states ❋ Unknown (2009)

The neurons of the supraoptic nucleus are magnocellular neurosecretory neurons - large neuroendocrine neurons which secrete their products, the hormones oxytocin and vasopressin into the circulation from their nerve endings in the posterior pituitary gland. ❋ Unknown (2009)

Amongst other effects, Ang II causes the secretion of AVP from the supraoptic region (found in mammalian brains) of the hypothalamus; is a potent dipsogen (stimulates the sensation of thirst) in an attempt to increase fluid volume; and results in the release of adrenocorticotropic hormone (ACTH) from the anterior pituitary gland. ❋ Unknown (2009)
