Providing the first glimpse of how associative memories are actually established in our brains, this book describes a research strategy for unravelling the mystery of memory and learning. The results of this experimental quest are described at several levels of biological complexity including animal behavior, neural systems, cellular and membrane physiology, and molecular regulation. The amply illustrated text is carefully structured to distinguish between observations and hypotheses, between attractive possibilities and empirical demonstrations. Dr Alkon progresses step-by-step through a series of experimental tests of intuitive conjectures on the nature of learning and memory. The book guides the reader through a scientific detective story that sheds new light on how we learn and how we remember.
