Neural and genetic determinants of creativity

Area of Science:

• Neuroscience
• Genetics
• Cognitive Science

Background:

• Creative thinking is crucial but its neural and genetic underpinnings are poorly understood.
• Existing research has not fully integrated brain connectome and genomic data to explain creativity.

Purpose of the Study:

• To investigate the neural and genetic basis of creative thinking.
• To develop a predictive model for creativity using multi-modal data.

Main Methods:

• Analyzed whole-brain functional connectivity (34,716 connections) and whole-genome data (309,996 SNPs) in 236 subjects across two datasets.
• Utilized the Torrance Tests of Creative Thinking to assess creativity.
• Employed a cross-validation framework to build and test predictive models.

Main Results:

• High creativity correlated with strong functional connectivity in executive control, attention, and memory networks (top-down) and weak connectivity in default mode and sensory networks (bottom-up).
• Creativity scores significantly correlated with genetic variations in neurotransmitter-coding genes (glutamate and GABA systems).
• A combined neuroimaging and genomic model predicted creativity with 78.4% accuracy, outperforming single-modality predictions.

Conclusions:

• Creative thinking is characterized by dominant top-down cognitive control over bottom-up sensory processing.
• Neurotransmitter system dynamics, particularly the balance between glutamate and GABA, modulate creativity.
• This research offers novel insights into the integrated neural and genetic architecture of creativity.
