Electrical stimulation of the lateral hypothalamus will cause an animal to:
A
begin eating.
B
stop eating.
C
become obese.
D
begin copulating.
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: -Abstract. Electrical stimulation of the lateral hypothalamus (LH) has two motivational effects: long trains of stimulation induce drive-like effects such as eating, and short trains are rewarding.

Detailed explanation-3: -The ventromedial nuclei is the satiety center, and when stimulated, it causes the sensation of fullness. On the other hand, the lateral hypothalamic area is the feeding center and when stimulated, it causes the sensation of hunger.

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).

Detailed explanation-5: -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).
