activity increased at the junction of three brain areas: the parietal region, just behind the crown of the head, which perceives sensory information and integrates it into the mysterious state called consciousness; the
temporal lobe, behind the temples and responsible for making sense of sound; and the occipital
lobe, located at the bottom back of the brain and responsible for processing vision.
