Seeing and Shaping Objects
Seeing and Shaping Objects
Current understanding of the basic optical and physiological processes involved in how we see is explained in a number of recent books on the subject by specialists in cognitive psychology and in the various branches of neuroscience. This chapter reviews some aspects of the topic that are particularly relevant to the subject of this book. Although in common parlance we speak of seeing with our eyes, in fact we do not see with our eyes, but with our brains. The eyes conduct light, via the retina at the back of the eyeball and the optic nerve, to the various different regions of the brain that are involved in seeing; as many as thirty have been suggested by neuroscientists. Seeing is thus a complex process that takes place in conjunction with other processes in which the brain is involved.
