Brain Connectivity in Smokers

Caption

This graphic shows activity in the brain, illustrated layer by layer. The colored regions represent the average functional connectivity with the posterior portion of the insula, an area of the brain linked to cigarette cravings in smokers. The top row represents the average connectivity among 44 study participants who successfully quit smoking, versus the average functional connectivity for 41 participants who relapsed, shown on the bottom row. A Duke Medicine study shows there is more connectivity between the insula and the somatosensory cortex among the smokers who quit compared to those who relapsed.
