The destruction of the amygdala makes the animal docile again, suggesting that the amygdala is responsible for aggressive behavior. Therefore, in a normal animal, the septum may inhibit the amygdala to prevent the expression of rage. Therefore, choice B is the correct answer. Choices A and C are both incorrect because they suggest that the septum itself is responsible for rage, which is not necessarily the case. Choice D is partially correct but is not the best answer because it does not explain why the amygdala plays a role in aggressive behavior. Choice E is incorrect because not all of the choices are correct.
