2
Fxn/stimulus of ventromedial hypothalamic nucleus
- mediates satiety
- destruction ==> hyperphagia
- stimulated by leptin
- destruction ==> hyperphagia
3
Fxn/stimulus of lateral hypothalamic nucleus
- mediates hunger
- destruction ==> anorexia
- inhibited by leptin
- destruction ==> anorexia
4
Fxn of anterior hypothalamic nucleus
- mediates heat dissipation via parasympathetics
- destruction ==> hyperthermia
- destruction ==> hyperthermia
5
Fxn of posterior hypothalamic nucleus
- mediates heat conservation via sympathetics
- destruction ==> hypothermia
- destruction ==> hypothermia
