Delta sleep-inducing peptide, abbreviated DSIP, is a neuropeptide that when infused into the mesodiencephalic ventricle of recipient rabbits induces spindle and delta EEG activity and reduced motor activities.

A modulation or 'programming' interaction of delta sleep-inducing peptide (DSIP) with endogenous opioid-peptidergic systems and exogenous intracerebrally or systemically administered amphetamine. The induction of cerebral MAO-A activity, a pronounced influence on the circadian rhythms of locomotion and intracerebral neurotransmitter as well as plasma protein and cortisol concentrations has been reported. DSIP was also shown to counteract experimentally induced stress situations in animals.  

An improvement of the psychomotor performance and the concentration capacity in humans beside sleep normalization and pronounced effects on withdrawal symptoms including pain states in alcoholics and opiate addicts was discovered. This encouraged a pilot study for a possible action of the peptide in humans suffering from chronic pronounced pain episodes. DSIP has stress-protective, antiseizure, and immunomodulating effects.
