At one time or another we have all been let down by our memories whilst at the same time we have probably been amazed by the seemingly insignificant details that are retained; occasionally we remember things that turn out not to have happened at all. In this enormously readable account renowned neurobiologist James McGaugh examines how the brain deals with experience and memory, and discusses what affects the success with which experience is stored. He explains that the main aid to long-term memory is an uninterrupted period of consolidation and that if this consolidation is in any way disrupted the reliability of the memory is reduced; conversely, if the experience is accompanied by a period of heightened stimulation, the brain releases hormones which actually speed that consolidation. As well as giving a thorough history of the study of memory, McGaugh brings a complex subject to the interested reader in a thoughtful and succinct book. (Kirkus UK)

Memory is central to our existence. But not all memories are created equal. As the novelist Doris Lessing observed, 'It's extraordinary how little we do remember. It's almost as if memory is not considered useful by nature'. So how does memory work, and why do most experiences leave little trace while some leave memories that last a lifetime? Drawing on many fascinating case studies, the author, a distinguished neuroscientist, reveals how some of the best clues to understanding how memories are created come from understanding how memories are lost. He shows how lasting memories are not stored instantly. Rather, the consolidation of long-term memory takes time, and the disruption of newly consolidating memories leaves them permanently weakened. But why is time required? Is the brain a design failure? Perhaps, but most likely not, says the author. The slow consolidation of memory has, he contends, an important adaptive consequence. It allows physiological processes activated by experiences to regulate the strength of the memory for the experiences. Experiences initiate the consolidation of memory. Emotionally arousing experiences also induce the release of stress hormones, which can then act on the brain to influence the consolidation of recent experience. Insignificant experiences therefore leave only fleeting traces and significant experiences become memorable - findings that have important implications for the controversial issues of post-traumatic stress disorder and repressed memory syndrome.
