[Mechanism of the action of the delta sleep-inducing peptide against a background of L-DOPA administration].

A reciprocal nature of the shifts in activity of type A and B monoamine oxidases has been observed under the effect of DSIP against the background of L-DOPA administration (50 micrograms/kg) in the subfractions from the rabbit sensorimotor cortex. The results suggest that the activation of type A monoamine oxidase and serotoninergic system is the basis of the adaptive behavior of animals.
