In Search Of Memory: The Emergence Of A New Science Of Mind

E-Book Overview

“A stunning book.”—Oliver SacksCharting the intellectual history of the emerging biology of mind, Eric R. Kandel illuminates how behavioral psychology, cognitive psychology, neuroscience, and molecular biology have converged into a powerful new science of mind. This science now provides nuanced insights into normal mental functioning and disease, and simultaneously opens pathways to more effective healing. Driven by vibrant curiosity, Kandel’s personal quest to understand memory is threaded throughout this absorbing history. Beginning with his childhood in Nazi-occupied Vienna, In Search of Memory chronicles Kandel’s outstanding career from his initial fascination with history and psychoanalysis to his groundbreaking work on the biological process of memory, which earned him the Nobel Prize. A deft mixture of memoir and history, modern biology and behavior, In Search of Memory traces how a brilliant scientist’s intellectual journey intersected with one of the great scientific endeavors of the twentieth century: the search for the biological basis of memory.

We want to understand the biological nature of perception, learning, memory, thought, consciousness, and the limits of free will. That biologists would be in a position to explore these mental processes was unthinkable even a few decades ago. Until the middle of the twentieth century, the idea that mind, the most complex set of processes in the universe, might yield its deepest secrets to biological analysis, and perhaps do this on the molecular level, could not be entertained seriously. The dramatic achievements of biology during the last fifty years have now made this possible. The discovery of the structure of DNA by James Watson and Francis Crick in 1953 revolutionized biology, giving it an intellectual framework for understanding how information from the genes controls the functioning of the cell. That discovery led to a basic understanding of how genes are regulated, how they give rise to the proteins that determine the functioning of cells, and how development turns genes and proteins on and off to determine the body plan of an organism. With these extraordinary accomplishments behind it, biology assumed a cen-<
