Deep in the human brain, two small but very important regions lie close together: the amygdala, which plays an important role in the generation and perception of emotions, and the hippocampus, which is a central switchboard for memories. These two small neighboring regions have until now been hard to tell apart in neuroimaging investigations of the living human because of their small dimensions, the amygdala being only the size of an almond. Ultra-high-field magnetic resonance imaging is now offering unprecedented clarity.
