Phantom limb pain - neuromatrix explains phantom limb pain Melzack and Wall: The gate control theory of pain, proposes that a mechanism in the dorsal horns of the spinal cord acts like a gate that inhibits or facilitates transmission from the body to the brain on the basis of the diameters of the active peripheral fibers, as well as the dynamic action of brain processes. The gate control theory, however, is not able to explain several chronic pain problems, such as phantom limb pain, which require a greater understanding of brain mechanisms..

• SBO6 Week 6 Workshop Material “STEP 2 – TRANSMISSION/CONDUCTION Once the PAN has been transduced, the action potential must be transmitted to the CNS and through the CNS before pain is perceived. Three steps are involved in nociceptive signal transmission: 1) projection to the CNS; 2) processing within the dorsal horn of the spinal cord; and 3) transmission to the brain. Each step in the transmission process is important to pain perception.”
