Increased Functional Connectivity in an Insula-Based Network is Associated with Improved Smoking Cessation Outcomes

suggest that relapse vulnerability is associated with weaker connectivity between the posterior insula and primary sensorimotor cortices. Perhaps greater connectivity in this network improves the ability to inhibit a motor response to cigarette cravings w

Smokers who quit may have brains hard-wired for success

Researchers reviewed brain scans of smokers who tried to quit and found the people who succeeded had something in common: a stronger connection between the insula, home to urges and cravings, and the somatosensory cortex, which handles touch and motor co
