"WebJul 21, 2012 · In the spinal cord, fast pain and slow pain are carried up to the brain via different pathways. The impulse of the fast pain goes to specific and limited areas on the surface of the brain (the cortex), allowing for the relatively precise localisation of the pain stimulus. The impulse from slow pain is distributed diffusely in the brain. " - Fast and slow pain pathways
