DSIP peptide molecular structure diagram from PubChem

Delta-sleep-inducing peptide (DSIP) is a neuropeptide that, when infused into the mesodiencephalic ventricle of recipient rabbits, induces spindle and delta EEG activity and lowers motor activity. It has been studied for sleep regulation, stress response modulation, and pain threshold effects.
