gate theory

gate theory
gate-control theory neural impulses generated by noxious painful stimuli and transmitted to the spinal cord by small-diameter C-fibers and A-delta fibers are blocked at their synapses in the dorsal horn by the simultaneous stimulation of large-diameter myelinated A-fibers, thus inhibiting pain by preventing pain impulses from reaching higher levels of the central nervous system. Called also gate hypothesis.
