This theory states that:
“Activation of large afferent fibers inhibit response of Wide Dynamic Range neurons and C fibers resulting in reduction of pain.”
Large afferent fibers are the A beta fibers which are large diameter fibers with myelin sheaths. They have fast conduction velocity and facilitate conduction of light touch, pressure and sensation stimuli.
This explains the relief brought about by a mother’s soft touch and kisses into a child’s wound after knocking him/herself. The light touch via the large fibers will inhibit or block the conduction of the pain fibers thereby reducing the pain.
How about emotional pain? Is it applicable? I hope so...
