The seats of pain – International

A group of researchers has identified the areas of the brain involved in chronic and acute pain. Four people with chronic pain that was not responding to treatments participated in the study. During episodes of pain, nerve activity was measured with electrodes implanted in the brain. It emerged that one area of ​​the cerebral cortex corresponded to chronic pain and another to acute pain. Brain activity would then make it possible to measure pain, he writes Nature Neuroscience.
