Neural substrates of attentional bias for smoking-related cues: an FMRI study.

ABSTRACT: Attentional bias for drug-related stimuli, as measured by emotional Stroop (ES) tasks, is predictive of treatment outcomes for tobacco smoking and other abused drugs. Characterizing relationships between smoking-related attentional bias and brain reactivity to smoking images may help in identifying neural substrates critical to relapse vulnerability. To this end, we investigated putative relationships between interference effects in an offline smoking ES task and functional MRI (fMRI) measures of brain reactivity to smoking vs neutral images in women smokers. Positive correlations were found between attentional bias and reactivity to smoking images in brain areas involved in emotion, memory, interoception, and visual processing, including the amygdala, hippocampus, parahippocampal gyrus, i
