Chronic low back pain is the most common cause of restricted activity in people over 45 years of age. However, its neurobiological mechanism remains unclear. Brain imaging studies suggest that brain activation in patients with chronic pain is different from that in normal individuals. Thalamus, anterior prefrontal lobe and cingulate gyrus may be involved in the pathophysiological processes of some chronic pain. Animal experiments with chronic pain have shown spinal chemical abnormalities. To understand whether chronic pain is brain-based
