The NRM receives afferent stimuli from the enkephalinergic neurons of the periaqueductal gray; the serotonergic neurons of the NRM then bilaterally project efferents to the enkephalinergic and dynorphin-containing interneurons of the substantia gelatinosa of the posterior grey column of the spinal cord. This neural path thus mediates pain perception through pre-synaptic inhibition of first-order afferent (sensory) neurons.[3]: 225
