A) Brain stimulation through electrodes that support self-stimulation often elicits motivated behaviors such as eating, drinking, and copulation.

D) Self-stimulation is associated with contingent tolerance.
E) both A and B

Option A suggests that brain stimulation through electrodes that support self-stimulation often elicits motivated behaviors such as eating, drinking, and copulation, which suggests that the self-stimulation involves the activation of natural reward circuits. Option B states that increasing levels of natural motivation sometimes increases the rate of self-stimulation, which further supports that self-stimulation involves the activation of natural reward circuits. Therefore, the correct choice is E, as both options A and B point towards the involvement of natural reward circuits. Option C, stating that self-stimulation at some brain sites is often aversive, and option D, stating that self-stimulation is associated with contingent tolerance, do not provide evidence for the involvement of natural reward circuits.
