Memory and Emotion

Book excerpt: Memories come in many different forms and vary substantially in strength; some, such as where you put your car keys, can be brief, while others remain in the mind forever. James McGaugh, a leading neurobiologist, provides an accessible and thought-provoking look at how we remember and why we forget. Beginning with the first scientific studies of learning and ending with the latest cutting-edge research, he explores how memories are made and preserved; why some experiences fade and disappear with time; how stress hormones effect the consolidation of memory; whether drugs would improve our ability to learn; and what studies of extraordinary memories and disorders tell us about the workings of the brain systems involved in memory formation.
