Why head and face pain causes more suffering: Sensory neurons in the head and face tap directly into the brain's emotional pathways -- ScienceDailyThe team found that sensory neurons that serve the head and face are wired directly into one of the brain's principal emotional signaling hubs. Sensory neurons elsewhere in the body are also connected to this hub, but only indirectly. The results may pave the way toward more effective treatments for pain mediated by the craniofacial nerve, such as chronic headaches and neuropathic face pain. "Usually doctors focus on treating the sensation of pain, but this shows the we really need to treat the emotional aspects of pain as well," said Fan Wang, a professor of neurobiology and cell biology at Duke, and senior author of the study. The results appear online Nov. 13 in Nature Neuroscience.
