Negative or neutral moods were induced in healthy volunteers who underwent heat pain whilst in an fMRI scanner .
Areas that showed increased activity during pain in the depressed mood state - left insula, thalamus, hippocampus, IFG, dlPFC, OFC, and the sACC. The thalamus and the insular cortex
are part of the afferent nociceptive network .
dlPFC, dorsolateral prefrontal cortex; IFG, inferior frontal gyrus; OFC, orbitofrontal cortex sACC – subgenual anteria cingulate cortex
Pain was rated more unpleasant after the sad mood induction. Depressed mood was associated with increases in negative pain-related cognitions (catastrophizing)

What other interventions to use?What other interventions to use?
Despite the frequent coexistence of depression , anxiety and
pain the magnitude and implications of that relationship are
