Pain receptors are usually free nerve endings and are receptors to chemical, mechanical and thermal pain sensation usually found in the skin, internal and joint surfaces.
Their findings suggest that a small group of neurons near the base of the brain, in the mesopontine tegmentum, has executive control over the alert status of the entire cerebrum and spinal cord, and can generate loss of pain sensation, postural collapse, and loss of consciousness through specific neural circuitry.
