title: [Affect from the biological and psychiatric viewpoint].
abstract: The human frame of mind is a biological and psychic problem. The man is able to influence his mood in contrast to the animal, because the human brain is functionally an open system. The questions, which result from this opinion will be demonstrated. The influence of psychopharmaca and of drugs is an actual problem of human behaviour and must be considered in the therapy of mental disturbances.
