An endogenous neuropeptide first characterised for inducing delta-wave (slow-wave) sleep, researched for sleep, stress and pain modulation, with mixed results.
Acts as a neuromodulator rather than a direct sedative, appearing to normalise dysregulated sleep-wake cycles and increase delta-wave EEG activity. Proposed NMDA-receptor involvement and MAPK interaction; widely distributed in the hypothalamus and limbic system. Its precise receptor remains poorly defined.
