Binding of the delta sleep-inducing peptide (DSIP) was studied in cultures of rat brainstem by means of autoradiography. Binding sites for [3H]DSIP were observed on small, medium-sized and large brainstem neurons but not on glial cells. Addition of unlabeled DSIP inhibited or markedly reduced binding of [3H]DSIP. It is suggested that brainstem neurons might possess receptors for this sleep-inducing peptide.
