57
Q

Hypothalamic nuclei:

anterior ==>

ventromedial ==>

lateral ==>

posterior ==>

The anterior nucleus facilitates sexual interest and specific sexual behaviors.

The ventromedial nucleus acts as a satiety center and stimulation of this area reduces appetite. This nucleus acts by inhibiting the lateral nucleus, which stimulates appetite.

The posterior nucleus, along with the contiguous reticular activating system, controls levels of arousal. Lesions in these areas cause lethargy and somnolence.

The supraoptic and paraventricular nuclei produce vasopressin and oxytocin.
