Results Insight or Aha! moment was a spontaneus event which could be enhanced by past experiences or watching comic story. Recently, neuroscience study has been focused on language problem solving by cognitive insight such as anagram and compound remote association. For affective insight, researcher was not aware any report by MRI or EEG study. However, from mindfulness study, EEG and MRI findings were the same as of cognitive insight that is, cingulate gyrus (CC) and prefrontal medial cortex (PFC) were activated and EEG changes were related to alpha and gamma wave thus these might be occurred in affective insight.

Conclusion Insight or Aha! moment could be classified into 2 type, i.e., affective and cognitive insight. Neuroscience study on insight mainly focused on language problem solving revealed that CC and PFC were activated.
