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. Weblocalised pain Slow, diffuse, dull pain Table 1 Characteristics of primary afferent fibres Dorsal horn of the spinal cord Aδ and C fibres synapse with secondary afferent neurones in the dorsal horn of the spinal cord. The dorsal horn can be divided histologically into ten layers called Rexed laminae.
