WebChronic pain afflicts as much as 50% of the population at any given time but our methods to address pain remain limited, ineffective and addictive. In order to develop new therapies an understanding of the mechanisms of painful sensitization is essential. We discuss here recent progress in the understanding of mechanisms underlying pain, and how these … The Gate Control Theory of Pain is a mechanism, in the spinal cord, in which pain signals can be sent up to the brainto be processed to accentuate the possible perceived pain, or attenuate it at the spinal cord itself. The 'gate' is the mechanism where pain signals can be let through or restricted. One of two … See more The pain gate mechanism is located in the dorsal horn of the spinal cord, specifically in the Substantia gelatinosa. The interneurons within the Substantia gelatinosa are what synapse to the primary afferent … See more The painful sensation that is perceived and experienced isn't only driven by the sensory event, but also the pain signals sent from the brain … See more
Gate Control Theory - an overview ScienceDirect Topics
WebConclusions: Dorsal root ganglion stimulation does not induce GABA release from the spinal dorsal horn cells, suggesting that the mechanisms underlying DRGS in pain relief are different from those of conventional SCS. The modulation of a GABA-mediated "Gate Control" in the DRG itself, functioning as a prime Gate of nociception, is suggested and ...

WebJun 1, 1982 · 'Pain-Gating' Mechanisms The original 'pain-gate' theory of Melzack and Wall has undergone extensive criticism and revision since its first proposal in 1965 (Handwerker, Iggo and Zimmermann 1975, Kenton, Crue and Carregat 1976, Nathan 1976, Strassburg, Krainick and Thoden 1977).
