Where did I put the car keys? Why can t I stop thinking about that car accident I saw? Henry II, Richard I, ......I know that person: all examples of everyday thoughts requiring brain memory, one human capability that we rely on to make sense of today and guide our tomorrow. This book describes an outside the box version of the memory mechanisms based on recognised biochemical and psychological theories and including a modicum of conjecture and personal opinion. At the end the reader will understand how we learn and remember and why emotional state and level of attention are important.
