WebIn all instances, the margin of safety for transmission was greater in small, slow fibers than in large, fast fibers. The variations seen in nerve response to tetrodotoxin application are explained by the presence of nerve fiber diffusion barriers; the large fibers show more diffusion protection than the small fibers.

WebFast pain is associated with rapid transmission of impulses from the periphery to the spinal cord in large diameter, myelinated Aδ fibers while slower-arising and longer-lasting pain (dull/aching) is due to transmission in smaller, unmyelinated C fibers ( Dubin and Patapoutian, 2010 ).
