The brain's ability to detect movement within the retinal image is crucial not only for determining the trajectories of moving objects, but also for identifying and interpreting image motion resulting from eye to head movements. This book summarizes our knowledge of how information about image motion is encoded in the brain. Features: * Valuable reference source for those involved in the rapidly expanding area of motion perception. * Strong emphasis on integration of physiological, computation, and psychophysical approaches. * Topics include : Principles of local motion detection, Inputs to local motion detectors, Integration of motion signals, Higher-order interpretation of motion, Motion detection and eye movements.
