This corresponds to the rest-activity cycle of the organism. Sensitization and individual differences to IP amphetamine, cocaine, or caffeine following adrnal intracranial amphetamine infusions. This helps to protect the organism from a lethal overactivation of the immune system, and minimizes tissue damage from inflammation.
