Many obviously organic brain diseases -- dyslexia, schizophrenia, attention-deficit disorder, genuine manic-depression, idiopathic epilepsy, and so forth -- still are pathologically ill-defined.

On the other hand, intense euphoria is harder to come by than everyday pleasures. Psychotherapy seldom begins with a complete physical. Direct ion-channel controlling receptors can respond in microseconds, whereas indirect second-messenger controlling receptors take milliseconds to produce a response.
