How Your Brain Creates ‘Aha’ Moments and Why They Stick

Neuroscientists have uncovered how the brain creates sudden "aha" moments by studying participants who viewed abstract black-and-white images while in brain scanners. When people experienced insight, three brain regions showed increased activity: the visual processing area, the emotion-processing amygdala, and the memory-forming hippocampus. This burst of brain activity explains why insightful discoveries create stronger, longer-lasting memories compared to gradually solved problems.
