How is creative thinking wired in the resting brain?

Highly creative individuals show stronger spontaneous communication between brain networks responsible for focused control and daydreaming.
Key findings
During rest, the highly creative group showed significantly stronger functional connectivity between the bilateral inferior frontal gyrus and key regions of the default mode network. Specifically, the left inferior frontal gyrus was more strongly connected to all four default mode regions, while the right inferior frontal gyrus showed greater connectivity to bilateral inferior parietal lobes. The highly creative group also exhibited increased resting-state connectivity between the right inferior frontal gyrus and a cluster of voxels in the left dorsolateral prefrontal cortex.
Methodology
The researchers selected groups of participants from an initial pool of 91 subjects based on their performance on a battery of six computerized divergent thinking tests. They compared 12 highly creative individuals with 12 less creative individuals, carefully matching them on intelligence, age, and personality. Each participant completed a scan where data were acquired for five minutes while they rested with their eyes closed.
Limitations
The study relies on resting-state scans, which measure brain activity at rest rather than active creative performance, so it cannot prove these specific connections directly cause creative thoughts in real time. Because the final analysis compared very small groups of 12 participants each, the findings may not generalize widely and lack statistical power. Additionally, the study's correlational design means we cannot rule out other underlying biological or cognitive factors that might drive both increased connectivity and divergent thinking ability.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Creative thinking is characterized by enhanced functional connectivity between the DMN and executive control regions such as the inferior frontal gyrus, showing cooperative network communication during rest.
Evidence for the claim as stated.
Cognitive traits, such as creative thinking and the indirect link between empathy and anxiety, are reflected in specific patterns of communication between frontoparietal and default mode networks.
Evidence for the claim as stated.
Highly creative individuals display elevated resting-state functional connectivity between the default mode network and executive control regions, specifically showing stronger functional connectivity between the right inferior frontal gyrus and the left dorsolateral prefrontal cortex.
Evidence for the claim as stated.
Highly creative individuals display significantly stronger spontaneous resting-state functional connectivity between executive control regions like the inferior frontal gyrus and default mode network nodes.
Evidence for the claim as stated.
