The mechanism of gate control theory can be used therapeutically. Gate control theory thus explains how stimulus that activates only nonnociceptive nerves can inhibit pain. The pain seems to be lessened when the area is rubbed because activation of nonnociceptive fibers inhibits the firing of nociceptive ones in the laminae. [4]
Gate Control Theory Firing of the inhibitory interneuron (responding to the non-painful stimuli) decreases the probability that the projection neuron (responsible for pain responses) will fire an action potential. The wide dynamic range (WDR) neuron was first discovered by Mendell in 1966. [1]
Ronald Melzack OC OQ FRSC (July 19, 1929 – December 22, 2019) was a Canadian psychologist and professor of psychology at McGill University. [1] [2] In 1965, he and Patrick David Wall re-charged pain research by introducing the gate control theory of pain.
The Gate Control Theory of Pain, first proposed in the 1960s by Melzack and Wall, states that the concurrent activation of tactile afferent nerve fibers inhibits activation of nociceptive afferent fibres. [1] Melzack and Wall suggested that a gating mechanism is present in the dorsal horn of the spinal cord.
Wall & Melzack's Textbook of Pain is a medical textbook published by Elsevier.It is named after Patrick David Wall and Ronald Melzack, who introduced the gate control theory into pain research in the 1960s.

Synaptic gating is the ability of neural circuits to gate inputs by either suppressing or facilitating specific synaptic activity. Selective inhibition of certain synapses has been studied thoroughly (see Gate theory of pain), and recent studies have supported the existence of permissively gated synaptic transmission. In general, synaptic ...
Primary afferent fibers contain many receptors along their projections, making them amenable to complex modulation. The constant influx of environmental stimuli, as sensed by primary afferent fibers, is subject to modulation to enhance or diminish stimuli (see also: gate control theory and gain control-biological). Because there are essentially ...
