Detailed explanation-1: -Electrical stimulation of the ventromedial hypothalamus enhances both fat utilization and metabolic rate that precede and parallel the inhibition of feeding behavior.
Detailed explanation-2: -Ventromedial nucleus of hypothalamus (VMH) has been designated as the satiety center [1]. Its stimulation causes cessation of eating in the animals, whereas bilateral lesions results in hyperphagia, polydypsia, increase in body weight and finickiness [2, 3].
Detailed explanation-3: -The three parts of the hypothalamus that regulate food intake are called the ventromedial nuclei, the lateral hypothalamic area, and the arcuate nucleus. The ventromedial nuclei is the satiety center, and when stimulated, it causes the sensation of fullness.
Detailed explanation-4: -The LH is generally known as the hunger center, and two of its main functions are the stimulation of feeding behavior and arousal. Electrical stimulation of the LH results in ravenous eating behavior, and animals are extremely motivated to work for a food reward (Stuber and Wise, 2016).
