A study using brain scans shows that flashes of insight reorganize neural patterns in the visual cortex and engage memory and emotion regions, helping embed the solution more deeply in long-term memory.

Five years in the making: our meta-analysis of 10 fMRI datasets across Asia, Europe, and North America (N=2,433). We find creative ability emerges from dynamic switching between default and executive brain networks, with optimal creativity at a "sweet spot."
