No insight effect was noticed anywhere within the temporal lobe of the left hemisphere.

About one-third of another before the subjects indicated solutions attained through insight, there is an abrupt burst of high-rate of recurrence activity, in accordance with solutions achieved without insight. This neural activity, associated with complicated cognitive processing often, was noticed at scalp electrodes over the same correct temporal area observed with fMRI, replicating the effect with new individuals and a different way of measuring brain activity.
