Brain Function and Psychotropic Drugs

Reward and punishment systems clearly serve adaptive functions in promoting behaviours which increase the chances of survival and preventing behaviours that lead in the opposite direction. In certain conditions, however, activity in these systems appears to be maladaptive, and these can be regarded as disorders of reward and punishment systems. Drug dependence and disorders of pain sensation are considered in this chapter in this category. Reward and punishment systems are also involved in eating and psychosexual disorders and in aggressive behaviour which are not considered in this chapter.

Keywords:   reward systems, punishment systems, drug dependence, pain sensation, psychosexual disorders, eating disorders
