The influence of the delta sleep-inducing peptide on the rabbit slow sleep was studied in "blind" experiments following the intravenous injection of its 30 nmol/kg dose. The duration of the slow sleep was assessed by the summary duration of ECoG sections of the sensorimotor and visual cortex with pronounced delta-activity. The results obtained after the injection of peptide and that of a control substance (saccharose) were compared with those obtained before the injection. No statistically significant differences were found. A tendency was observed towards a decrease in the duration of the slow sleep and increased motor activity of the animal at the second hour after peptide injection. Hence, the delta sleep-inducing peptide is not a substance with pronounced hypnogenic properties.
