This systematic review and meta-analysis examined brain activation patterns in 965 participants drawn from 33 different neuroimaging studies. The goal was to identify consistent neural signatures that appear during optimal creative performance. The researchers looked for specific brain areas that turned on or off when people performed creative tasks well.
The main results showed that superior creative performance was linked to increased activation in the left middle frontal gyrus, left superior frontal gyrus, and left inferior parietal gyrus. At the same time, there was decreased activation in the right precuneus. Further analysis suggested that longer training duration and greater professional experience predicted stronger activation in some of these left-sided regions.
The study did not find significant effects related to age or sex ratio. While the findings offer potential targets for future training and neuromodulation-based interventions, readers should understand that this research describes correlations found in existing data. It does not yet provide a proven method for improving creativity through brain stimulation or specific exercises.
The main reason to be careful is that these results come from a mix of studies with varying designs, and no safety concerns were reported because no active intervention was tested. Readers should take from this that our brains show distinct patterns during high creativity, but more research is needed to understand how to use this knowledge safely and effectively.
