The Visual Brain in Action

Although the mechanics of how the eye works are well understood, debate still exists as to how the complex machinery of the brain interprets neural impulses supplied by the eye. The authors of this book take a step back to ask, "What is the function of vision?" in an attempt to understand the evolutionary origins and therefore functions of the visual system. They propose that not one, but two "visual brains" exist which are responsible in a quasi-independent way for visual perception and the visual control of action.
