2Modulation of Pain Transmission Modulation of
pain transmission in the dorsal horn of the
spinal cord, illustrating the interaction of
small diameter pain afferents and large diameter
mechanoreceptors (touch) afferents, as well as
the influence of descending neurons on afferent
pain pathways 5HT serotonin, NE
