Detailed explanation-1: -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).

Detailed explanation-2: -The hypothalamus is a region of the brain that plays a critical role in feeding regulation. It has been revealed by various physiological experiments that the feeding-regulating center is confined to the ventromedial hypothalamus, lateral hypothalamus (LH) and arcuate nucleus (ARC).

Detailed explanation-3: -The hypothalamus acts as the control center for hunger and satiety. Part of the hypothalamus, the arcuate nucleus (or, in humans, the infundibular nucleus), allows entry through the blood-brain barrier of peripheral peptides and proteins that directly interact with its neurons.

Detailed explanation-4: -Electrical or optogenetic stimulation of lateral hypothalamic (LH) GABA neurons induces rapid vigorous eating in sated animals. The dopamine system has been implicated in the regulation of feeding.

Detailed explanation-5: -The lateral hypothalamus (LH) is a key brain area in the regulation of feeding behavior. The LH is known as the hunger center subsequent to classical reports showing that lesion of the LH suppresses food intake and electrical stimulation of the LH increases food intake.
