Temporal lobes are primarily for auditory perception, receptive components of language, declarative and visual memory, and emotion. Patients with right temporal lobe lesions often lose acuity for nonverbal auditory stimuli (eg, music). Injuries to the left temporal lobe greatly interfere with recognition, memory and language formation.
The right temporal lobe of the brain is directly linked with signs of perception and association between words and things, so the research exposed in the question was able to realize that the solutions that occurred with a sudden flash of perception in the research participants, were accompanied by an explosion of activity in the right temporal lobe of the brain.
