[Category of needs in its general biological and psychosomatic aspects].

Analysis of psychoemotional stress which directly affects the health of the population shows that progress in studying stress and in prevention of its unfavourable consequences depends a great deal on the understanding of the human needs problem. At the same time the problem of the origin, evolution and transformation of needs is a subject of theoretical biology, since the dynamics of needs is the basis of self-development of the live nature, the specific (essential) force of live systems, the drive and aim of their active behaviour. The paper formulates the problems of further study of needs by theoretical biology, the science of human higher nervous activity and other adjacent spheres of science.
