Abstract

Highlights: A DMN subnetwork was related with creativity with its within-module degree. Industriousness moderated the link between the DMN subnetwork and creativity. Functional connectivity predicted creativity in the high-industriousness group. Abstract: Creativity has been consistently linked to the default mode network (DMN) and conscientiousness. However, the specific core regions that are involved in the relationship between the DMN and creativity and the manner in which conscientiousness influences the neural mechanism that underlies creativity remain unexplored. Therefore, in the present study, we used a combination of graph theory techniques and affinity propagation clustering (APC) to identify the core subnetworks of the DMN that are related to creativity and examine predictive relationships between creativity and resting-state functional connectivity (RSFC). Additionally, the moderating role that two lower-order facets of conscientiousness, namely, industriousness and orderliness, play in this relationship was explored. The results showed that creativity was positively associated with the within-module degree (WMD) of one subnetwork of DMN (i.e., DMN2) and that industriousness was the only facet of conscientiousness that moderated this relationship. Specifically, creativity could be successfully predicted from the RSFC between DMN2 regions and all DMN regions in the high-industriousness group but not the low-industriousness group. Taken together, these results suggest that a core DMN subnetwork is crucial for creativity and that industriousness moderates the association between creativity and the DMN subnetwork.
