In turn the nucleus raphe magnus assignments to the substantia gelatinosa region in the dorsal horn and mediates the feeling of spinothalamic inputs. This is performed first via the nucleus raphe magnus sending serotoninergic neurons to neurons in the dorsal wire, that subsequently secrete enkephalin into the interneurons that carry pain notion.[15] Enkephalin capabilities by binding opioid receptors to cause inhibition with the post-synaptic neuron, So inhibiting pain.[11] The periaqueductal gray also consists of opioid receptors which explains one of many mechanisms by which opioids such as morphine and diacetylmorphine show an analgesic result.
