Brain implants reveal chronic pain signals
Scientists have a new and clearer view of chronic pain in the brain. Over several months, electrodes implanted in the four people’s brains picked up specific signs of their persistent pain. This detailed look at chronic pain, published May 22 in Nature Neuroscience, suggests new ways to reduce intolerable symptoms. Catherine Martucci, a neuroscientist who studies chronic pain at Duke University School of Medicine, said the approach “gives the brain a way to track pain,” Science News reported. Chronic pain is very common. From 2019 to 2020, more American adults were diagnosed with chronic pain than with diabetes, depression and hypertension, researchers reported at the JAMA Network Open May 16. Pain is also incredibly complex, complex, influenced by the body, brain, situations, emotions and expectations, says Martucci. This complexity makes chronic pain invisible to outsiders and very difficult to treat. One treatment is electrical stimulation of the brain. As part of a clinical
