This study examines how Pavlovian bias affects smoking cessation success and neurocognitive changes during nicotine withdrawal, finding that higher bias correlates with treatment failure and relapse risk.

This study examines longitudinal changes in brain network functional connectivity during smoking cessation, finding that successful quitters show normalization of pre-quit connectivity in salience-executive and salience-default mode networks.

This study uses tDCS to modulate the dorsolateral prefrontal cortex and finds reduced Pavlovian bias in the punishment domain, suggesting a causal role in balancing decision-making systems.
