Researchers from the University of Texas (UT) at Dallas and others traced the path of pain signals between the brain and spinal cord in mice and found removing a group of dopamine-containing cells selectively reduced chronic pain.
Senior author Ted Price, associate professor in behavioral and brain sciences at UT Dallas, says the study reveals a new role for dopamine in helping maintain chronic pain states, and suggests:
“This may open up new opportunities to target medicines that could reverse chronic pain.”
