An insight arrives with a feeling: the sudden click of a problem resolving itself, accompanied by relief and a small thrill. That sensation is not incidental. Researchers studying what happens in the brain at the moment of an aha have found distinct patterns of activity, and evidence that solutions reached this way are remembered better than ones worked out methodically.
Insight appears to involve a burst of high-frequency activity in regions associated with integrating information, often preceded by a period of quiet in the areas that were stuck. The brain seems to be stepping back from a local dead end and allowing broader associations to form. Imaging studies show that this shift can be detected in the seconds before a person reports a solution.
The memory advantage is the more practical discovery. Insights are accompanied by stronger, more durable encoding, possibly because the sudden restructuring of a problem engages attention and emotion. That has implications for education and for anyone trying to learn difficult material: struggling productively may be more valuable than being shown the answer.
