WebIntroduction. Once a pain signal from the ascending pathway reaches the somatosensory cortex, it triggers the descending pain modulatory system. The goal of this pathway is to allow the organism to function enough to respond to the pain source by reducing the pain signal through neuronal inhibition ie the "top down" modulation of pain.
