Why do we remember events from our childhood as if they happened yesterday, but not what we did last week? Why does our memory seem to work well sometimes and not others? What happens when it goes wrong? Can memory be improved or manipulated, by psychological techniques or even 'brain implants'? How does memory grow and change as we age? And what of so-called 'recovered' memories? This book brings together the latest research in neuroscience and psychology, and weaves in case-studies, anecdotes, and even literature and philosophy, to address these and many other important questions about the science of memory - how it works, and why we can't live without it.
