Short-term meditation modulates brain activity of insight evoked with solution cue.
Social Cognitive and Affective Neuroscience January 1, 2015 Xiaoqian Ding, Yi-Yuan Tang, Chengyue Cao et al.
After five hours of meditation training, compared with the same amount of relaxation, participants showed greater brain activity in the right cingulate gyrus, insula, putamen, inferior frontal gyrus, and bilateral middle frontal gyrus, inferior parietal lobule, and superior temporal gyrus when presented with a solution to a problem they had failed to solve. The authors speculate that these regions may support detecting conflict, breaking mental set, restructuring problem representation, error detection, and the 'Aha' feeling of insight.
