Question

Quizplus · Accepted Answer

The ventromedial hypothalamus (VMH) is known to play a role in regulating hunger and satiety. If it is destroyed, the rat would lose its ability to feel full or satisfied after eating, leading it to continuously overeat and eventually become obese. Therefore, the most likely outcome would be that the rat would eat until it becomes obese. The other choices are less likely, as the destruction of the VMH has a larger impact on hunger and satiety than on thirst or salt preference.
