- •
The default mode network (DMN) is involved in internally focused cognition.
- •
We show less DMN suppression when nicotine-dependent smokers view smoking cues.
- •
The dorsal anterior cingulate cortex (dACC) may play a role in modulating the DMN.
- •
We show an association between dACC glutamate and DMN reactivity to smoking cues.
