Neuronal regulation of vasculature and inflammation is demonstrated with experiments that exhibit redness, warmth, and swelling unbiased on the sensory nerve source [144]. Neurogenic inflammation is often a method dependant on direct electrical nerve stimulation which generates vasodilation and permeability [164]. This method is usually a probable system to the mediation of axon–axon reflexes that transduce the signal in neighboring axons via calcium inflow and antidromic signaling and triggers the release of mediators stored in vesicles Found for the axon terminals from the periphery.
