'Aha!-moments are characterized by hyperactivation in (a) nucleus accumbens, which has been shown to be involved in the feeling of relief, ease, and joy, (b) VTA, which is related to the encoding of certainty about a decision, (c) the posterior hippocampus, responsible for memory reorganization following an insight, and (d) aSTS/STG associated coarse semantic coding [ ... ] As those structures are part of a dopaminergic pathway, associated with reinforcement, we suggest the Aha!-Moment as a special form of fast retrieval, combination, and encoding process. Future research is needed...'
