ABSTRACT
The role of attention in creative cognition remains controversial. Neuroimaging studies have reported activation of brain regions linked to both cognitive control and spontaneous imaginative processes, raising questions about how these regions interact to support creative thought. Using functional magnetic resonance imaging (fMRI), we explored this question by examining dynamic interactions between brain regions during a divergent thinking task. Multivariate pattern analysis revealed a distributed network associated with divergent thinking, including several core hubs of the default (posterior cingulate) and executive (dorsolateral prefrontal cortex) networks. The resting-state network affiliation of these regions was confirmed using data from an independent sample of participants. Graph theory analysis assessed global efficiency of the divergent thinking network, and network efficiency was found to increase as a function of individual differences in divergent thinking ability. Moreover, temporal connectivity analysis revealed increased coupling between default and salience network regions (bilateral insula) at the beginning of the task, followed by increased coupling between default and executive network regions at later stages. Such dynamic coupling suggests that divergent thinking involves cooperation between brain networks linked to cognitive control and spontaneous thought, which may reflect focused internal attention and the top-down control of spontaneous cognition during creative idea production.

ROI-to-ROI temporal connectivity for the general task contrast (alternateuses > object characteristics) with the left precuneus specified as the sourceROI (black sphere) and all other ROIs specified as targets (red spheres).Regions labeled in black on the right show positive connectivity with the source ROI; regionslabeled in gray were not significant.

f7: ROI-to-ROI temporal connectivity for the general task contrast (alternateuses > object characteristics) with the left precuneus specified as the sourceROI (black sphere) and all other ROIs specified as targets (red spheres).Regions labeled in black on the right show positive connectivity with the source ROI; regionslabeled in gray were not significant.

Mentions: We then assessed temporal connections between the precuneus source ROI and the targets (see Fig. 7). During the first time window, the precuneus showed increased functionalconnectivity with the left insula, left MTG, and right PMC (see Fig. 7).During the second window, the precuneus showed sustained coupling with these regions and additionalcoupling with the right insula and left temporal pole (i.e., STG). This pattern persisted throughoutthe third time window, with additional connectivity found with the right MTG and left RLPFC. Duringthe fifth time window, the precuneus showed connectivity with bilateral MTG and the left RLPFC; nosignificant connectivity differences were found during the final time window.
