This really is done initially through the nucleus raphe magnus sending serotoninergic neurons to neurons while in the dorsal cord, that consequently secrete enkephalin to your interneurons that carry pain notion.[fifteen] Enkephalin functions by binding opioid receptors to cause inhibition with the article-synaptic neuron, Therefore inhibiting pain.[11] The periaqueductal grey also incorporates opioid receptors which clarifies one of several mechanisms by which opioids for instance morphine and diacetylmorphine exhibit an analgesic result.

It is assumed which the lateral pathway in the spinal twine towards the ventrocaudal thalamus and also to the cortex is accountable largely for sharp, well-localized pains that arise near the system floor. In contrast, the medial spinoreticulothalamic pathway responds extra to stimuli of deep somatic and visceral structures.
