Creativity and the default network: A functional connectivity analysis of the creative brain at rest

Area of Science:

• Neuroscience
• Cognitive Psychology

Background:

• Creative idea generation is a complex cognitive process.
• Neuroimaging studies suggest involvement of prefrontal cortex and default network in divergent thinking.

Purpose of the Study:

• To investigate the relationship between creative ability and brain functional network organization.
• To examine functional connectivity differences in high- versus low-creative individuals.

Main Methods:

• Resting-state functional magnetic resonance imaging (fMRI) was employed.
• Participants were categorized into high- and low-creative groups based on divergent thinking tests.
• Seed-based functional connectivity analysis was performed on key brain regions.

Main Results:

• High-creative individuals showed greater functional connectivity between the left inferior frontal gyrus (IFG) and the default mode network.
• The right IFG also demonstrated increased connectivity with the inferior parietal cortex and dorsolateral prefrontal cortex in high-creative individuals.

Conclusions:

• Enhanced functional connectivity between the inferior prefrontal cortex and default network characterizes high creativity.
• This suggests increased cooperation between cognitive control and imaginative processing regions in creative individuals.
