Differences in brain activation in the left and right hemisphere seem to be indicative of insight versus non-insight solutions.<ref name="Bowden & Beeman (2003)">{{cite journal|last1=Bowden|first1=Edward M.|last2=Jung-Beeman|first2=Mark|title=Aha! Insight experience correlates with solution activation in the right hemisphere|journal=Psychonomic Bulletin & Review|date=1 September 2003|volume=10|issue=3|pages=730–737|doi=10.3758/BF03196539|pmid=14620371|doi-access=free}}</ref> Presenting RATs either to the left or right visual field, it was shown that participants having solved the problem with insight were more likely to have been shown the RAT on the left visual field, indicating right hemisphere processing. This provides evidence that the right hemisphere plays a special role in insight.<ref name="Bowden & Beeman (2003)"/>

[[fMRI]] and [[EEG]] scans of participants completing RATs demonstrated particular brain activity corresponding to problems solved by insight.<ref name=" Kounios & Beeman (2009)" /> For example, there is high EEG activity in the alpha- and gamma-band about 300 milliseconds before participants indicated a solution to insight problems, but not to non-insight problems.<ref name= "Kounios & Beeman (2009)" /> Additionally, problems solved by insight corresponded to increased activity in the temporal lobes and mid-frontal cortex, while more activity in the [[posterior cortex]] corresponded to non-insight problems.<ref name="Kounios & Beeman (2009)" />  The data suggests there is something different occurring in the brain when solving insight versus non-insight problems that happens right before the solving of the problem. This conclusion has been supported also by eye-tracking data that shows an increased eye blink duration and frequency when people solve problems via insight. This latter result, {{clarify|text=paired with an eye pattern oriented to look away from sources of visual inputs|reason=paired how, by whom? is this observed or induced?|date=August 2023}} (such as looking at blank wall, or out the window at the sky) proves different attention involvement in insight problem solving vs. problem solving via analysis.<ref>{{cite journal |last1= Salvi |first1= Carola |last2= Bricolo |first2= Emanuela |last3= Franconeri |first3= Steven|last4=Kounios|first4=John|last5=Beeman|first5=Mark|title=Sudden insight is associated with shutting out visual inputs|journal=Psychonomic Bulletin & Review|date=December 2015|volume=22|issue=6|pages=1814–1819|doi=10.3758/s13423-015-0845-0|pmid=26268431|doi-access=free|hdl=10281/93524|hdl-access=free}}</ref>
