Cognitive neuroscientists have studied top-down control extensively and have demonstrated an important role for dorsolateral prefrontal cortex and anterior cingulate cortex. 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.
