Lesioning the ventromedial nucleus of the hypothalamus and the lateral hypothalamus affects hunger regulation by damaging the "on and off" signals for feeding. The ventromedial nucleus is responsible for turning off hunger when enough food has been consumed, while the lateral hypothalamus is responsible for turning on hunger when the body needs more energy. Lesioning both areas can disrupt this balance and lead to either excessive hunger or loss of appetite. Liver functions and stomach contractions are not directly regulated by these hypothalamic areas, and the pleasure of sham feeding is not a primary regulator of hunger.
