This process is really a probable mechanism for your mediation of axon–axon reflexes that transduce the signal in neighboring axons by way of calcium inflow and antidromic signaling and results in the release of mediators stored in vesicles Positioned with the axon terminals within the periphery.

In accordance with the convergence-facilitation speculation, the track record (resting) activity of pain projection neurons while in the spinal cord that receive input from one somatic region is amplified (facilitated) from the spinal cord by activity arising in nociceptors originating in A further location of the body. In this particular design, nociceptors producing the track record exercise originate within the area of perceived pain and tenderness; the nerve exercise producing the facilitation originates in other places, for example, in a myofascial induce level.
