Аннотация
The effects of alaptide, a new analog of melanostatine, on self-stimulation of the lateral hypothalamus, rotation behavior in rotometer, and stereotypy were studied in rats bred in social isolation from other animals beginning from the 17th day of birth and rats bred in groups. Alaptide potentiated amphetamine-stimulated behavior only in rats reared in social isolation. This effect was lateralized: the left rotation dominated. In rats reared in isolation and in groups the effects of alaptide on self-stimulation were oppositely directed: in the former it increased and in the latter decreased the rate of self-stimulations with oppositely directed changes in pedal pressing duration. At the same time, alaptide suppressed the effects of amphetamine on self-stimulation of rats reared in isolation. The central dopamine mechanisms of melanostatine action are discussed.
