Brain Regions Identified That Influence What We Remember Or Forget
..." Brewer said. Activity in one region of the right prefrontal
lobe and several areas on theright and left inner aspects of the temporal lobes -- called the medial temporallobe system -- did predict whether the individuals would later remember thepicture very well, somewhat or not at all, he said. The area in th...
