Resting-state functional connectivity between the dorsal anterior cingulate cortex and thalamus is associated with risky decision-making in nicotine addicts

Abstract: Nicotine addiction is associated with risky behaviors and abnormalities in local brain areas related to risky decision-making such as the dorsal anterior cingulate cortex (dACC), anterior insula (AI), and thalamus. Although these brain abnormalities are anatomically separated, they may in fact belong to one neural network. However, it is unclear whether circuit-level abnormalities lead to risky decision-making in smokers. In the current study, we used task-based functional magnetic resonance imaging (fMRI) and… Show more

“…The extracted peak coordinates were { x, y, z } = {−42, 20, 5} (left insula), {39, 26, −8} (right insula), {−3, 17, 58} (dorsal ACC). These seed regions are spatially similar to salience network nodes recently identified during a risky decision-making task (Wei et al, 2016). Consequently, 5 mm radius spherical ROIs were centered on these peaks and used as seeds for whole brain seed-to-voxel connectivity analysis (Kelly et al, 2010) (Fig.…”

“…Cigarette smokers similarly showed reduced connectivity between the thalamus and the anterior cingulate cortex, with findings also showing reduced connectivity with the caudate and the dorsolateral PFC; the strength of the dorsolateral PFC-thalamus connectivity was negatively associated with severity of nicotine dependence [133]. Counterintuitively, a positive correlation between dorsal anterior cingulate cortexthalamus connectivity strength with both nicotine dependence and risk taking behaviour in a Balloon Analogue Risk Task was reported in cigarette smokers, though this study used ROI to ROI rather than seed to whole brain connectivity as most other studies did, which may bias the results based on ROI selection [134]. Compared with healthy individuals, ketamine-dependent individuals showed reduced connectivity between the PFC, the motor/supplementary motor area, and posterior parietal regions and the thalamus, with connectivity between the posterior parietal cortex and the lateral dorsal thalamus correlated negatively with ketamine craving [135].…”

“…For instance, connectivity changes in key regions of the basal ganglia and the cingulo-opercular network have previously been reported in both risk-taking and risk-averse behaviors (Cox et al, 2010;DeWitt et al, 2014), but changes in these networks were not evident in our study. Likewise, the relation between delay discounting, probability discounting for gains, and RSFC seems to be stronger in conduct and addiction disorders (Wei et al, 2016;Zhu, Cortes, Mathur, Tomasi, & Momenan, 2015), but more sensitive techniques seem to be necessary for the detection of such differences in healthy sam ples. Nevertheless, our results provide, for the first time, in sight into the brain's functional architecture that may underlie risk seeking with respect to losses in healthy young males.…”
