AP PSYCHOLOGY

Detailed explanation-1: -The correct solution to this problem is provided by a. starve to death. To elaborate, the lateral hypothalamus is responsible for both activating and inhibiting feeding behavior. Therefore, if a rat’s lateral hypothalamus was destroyed the rat will not feel hungry and will not initiate any feeding behavior.

Detailed explanation-2: -It is well known that lesions of the lateral hypothalamus (LH) produce aphagia. Several previous studies have reported that lateral hypothalamus damage produces food aversion in addition to aphagia. However, damage to other regions near the LH also produce aphagia and enhanced aversion.

Detailed explanation-3: -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-4: -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-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).
