| Research Abstract |
Our main finding was shows a significant activate of Doroso lateral prefrontal cortex (DLPFC) in OA groups rather than normal subjects, and DLPFC activation has strong connection with pain matrix in normal subjects rather than OA groups． It is known that DLPFC function has related pain modulation． It seems that DLPFC exerts active control on pain perception by modulation corticosubcortical and corticocortical pathway in OA patient．
