After a portion of a rat's brain is destroyed, a scientist records dramatic weight gain in the rat. The portion of the rat's brain which was destroyed is most likely Correct Answer the hypothalamus

The hypothalamus is a region of the brain located below the thalamus that controls both the autonomic nervous system and the activity of the pituitary gland, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity. The hormone leptin binds to receptors in the hypothalamus to signal the brain that the stomach is full. Destruction of the ventromedial nucleus of the hypothalamus leaves the lateral hypothalamus to operate uninhibited, causing the rat to always feel hungry and become obese.
