    Here, "state" refers to different "amounts" of external/physical consciousness, from a total absence in coma, persistent vegetative state and general anesthesia, to a fluctuating and limited form of conscious sensation in a minimally conscious state such as sleep walking or during a complex partial epileptic seizure. [11]

  7. Hypothalamus - Wikipedia

    en.wikipedia.org/wiki/Hypothalamus

    These hypophysiotropic hormones are stimulated by parvocellular neurosecretory cells located in the periventricular area of the hypothalamus. After their release into the capillaries of the third ventricle, the hypophysiotropic hormones travel through what is known as the hypothalamo-pituitary portal circulation.

    Collectively, hormones regulate many physiological processes. The neuroendocrine system is the mechanism by which the hypothalamus maintains homeostasis , regulating reproduction , metabolism , eating and drinking behaviour, energy utilization , osmolarity and blood pressure .

    The blood vessels carry the peptides to the anterior pituitary gland, where they regulate the secretion of hormones into the systemic circulation. The parvocellular neurosecretory cells include those that make: Corticotropin-releasing hormone (CRH), which regulates ACTH secretion from the anterior pituitary gland
