In a provocative study just published in the new England Journal, NIDA-supported scientists reported they were able to "see" physical pain on MRI brain scans and, for the first time, measure its intensity and tell whether a drug was relieving it. Though the research is in its early stages, the development of a reliable signature, at least for physical pain in the brain opens the door to a host of research and treatment opportunities.
