The Hypothalamus
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The hypothalamus regulates hunger, thirst, body temperature, and sexual behavior, and controls the pituitary gland.
Show
Body temperature rising above set point triggers a hypothalamic response that starts sweating.
Watch for
The hypothalamus is small and central to nearly everything. Size is a poor guide to importance in the brain.
