 | | At first this technology served primarily to refine a basic map of the brain's main functional areas—showing, for instance, that certain regions in either hemisphere process and generate language or that the amygdala, an almond-sized area near the brain's center, acts as a sort of hub connecting sensory perception, emotion, and memory. |
 | | Scan studies have tracked the maturation of decision-making regions during adolescence; clarified how we store, retrieve, and lose memories; and identified the neural correlates of fear, distraction, and affection, as well as of various character traits, including extraversion, empathy, and persistence. |
 | | This means that the only way that a brain scan can yield an accurate pattern that is unique to a particular stimulus/activity/task is to track the temporal changes of activity in all regions of cortex (and not simply the particular "brain centers" associated with the activity through neurological lesion studies). |
