Neuware - 'Spotting a face in a crowd is easy. We can do it from almost any angle, up close or far away, in person or in a picture. We do it so often that we take it for granted. But object recognition, the neural process that enables us to find that face, is hard. Your brain is small and slow. It has neither the time nor the capacity to store and recall whole images of everything you see from every possible angle. Rather, brains work by figuring out what is important to see and what isn't. And they must be able to figure this out on their own, without guidance from anything else. So in order to understand how you recognize your friend at a party, your suitcase on a luggage carousel, or person waiting in the shadows, you first must understand how your brain teaches itself to see. The answer to that question can explain how the brain learns nearly anything. It will revolutionize our understanding of both human and artificial intelligence. In We Know It When We See It, pioneering neuroscientist Richard Masland unravels these mysteries by exploring the strange and mind-bending processes of human vision. The key insight is that learning is shaped by need. Our brains have evolved basic ways of processing information regulated by evolution. By applying these genetically determined rules to the basic mechanism of brain cells-a long-ignored but visionary concept known as the Hebb synapse-our brains have enough innate guidance to begin making sense of the world around them without any help, and to learn new things. Covering everything from what happens when photons hit your retina, to the neuroplasticity of real nerve nets, to what a computer algorithm must be able to do before it can be called truly 'intelligent,' to why some people have neurons that only fire in response to Jennifer Aniston's face, We Know It When We See It is a deep and thoughtful examination of how our brains make sense of the world'.

Synopsis

A Harvard researcher investigates the human eye in this insightful account of what vision reveals about intelligence, learning, and the greatest mysteries of neuroscience.

Spotting a face in a crowd is so easy, you take it for granted. But how you do it is one of science's great mysteries. And vision is involved with so much of everything your brain does. Explaining how it works reveals more than just how you see. In We Know It When We See It, Harvard neuroscientist Richard Masland tackles vital questions about how the brain processes information -- how it perceives, learns, and remembers -- through a careful study of the inner life of the eye.

Covering everything from what happens when light hits your retina, to the increasingly sophisticated nerve nets that turn that light into knowledge, to what a computer algorithm must be able to do before it can be called truly "intelligent," We Know It When We See It is a profound yet approachable investigation into how our bodies make sense of the world.

À propos de l?auteur

Richard Masland is the David Glendenning Cogan distinguished professor of ophthalmology and professor of neuroscience at Harvard Medical School. For many years he was director for research in ophthalmology at Harvard's Massachusetts Eye and Ear Infirmary, the world's largest vision research institute. He is a fellow of the AAAS, a former Howard Hughes Medical Institute investigator, and a recipient of the Proctor Medal and Alcon Research Award, among others. Masland has made groundbreaking contributions to the study of neural networks and to the reversal of blindness. He divides his time between Boston, Massachusetts and Frenchtown, Maryland.
