Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The part of the hypothalamus that produces hunger signals
A
lateral hypothalamus
B
ventromedial hypothalamus
C
homeostasis hypothalamus
D
None of the above
Explanation: 

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: -General Functions of the Lateral Hypothalamus LH neurons control feeding, blood pressure, heart rate, water intake and sodium excretion largely through the activation of adrenergic receptors (Shiraishi, 1991; Saad et al., 2000; Mendonca et al., 2018).

Detailed explanation-3: -the region of the hypothalamus that may be involved in the regulation of eating. Lesions of the lateral hypothalamus in animals result in fasting and weight loss. Stimulation of that part of the brain increases food intake.

Detailed explanation-4: -Within the hypothalamus are nerve cells that, when activated, produce the sensation of hunger. They do so by producing two proteins that cause hunger: neuropeptide Y (NPY) and agouti-related peptide (AGRP). Quite close to these nerve cells is another set of nerves that powerfully inhibit hunger.
