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 general task contrast (alternateuses > object characteristics) with the right DLPFC specified as the source ROI(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.

f8: ROI-to-ROI temporal connectivity for general task contrast (alternateuses > object characteristics) with the right DLPFC specified as the source ROI(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 explored temporal connectivity with the right DLPFC target ROI. During the first two timewindows (TRs 2-3), the RDLPFC did not show any significant connectivity differences with the targetROIs. However, during the third time window, the DLPFC showed increased connectivity with regionswithin the DMN, including the right PCC and right IPL, in addition to left RLPFC, left temporalpole, and right PMC (see Fig. 8). The DLPFC showed sustained coupling with theright IPL during the fourth time window, and no significant differences emerged during the finaltime window. Taken together, results from the temporal connectivity analyses revealed dynamiccoupling between core regions of the default, salience, and executive networks at different stagesof divergent thinking.
