Brigham and Women's Hospital Studies Brain Processing for Pain
announced that researchers at the hospital have found that specific brain patterns appear to track the severity of pain reported by patients.
Researchers used a brain imaging technique called arterial spin labeling to examine patterns of brain connectivity of those who suffer from chronic back pain and those who don't. They found that when a patient moved in a way that increased their back pain, a network of brain regions called default mode network exhibited changes in its connections.
With further research, this could be a step toward developing an objective scale for measuring pain in humans.
