Ability to detect light is, of course, fundamental for vision, but other aspects, such as detection of motion and determining other qualities of an object, such as shape and details, color, size, and distance, help to form our visual percept. The processing of the output from the photoreceptors starts in the retina (Figure 2.15), but countless neurons in the brain finally shape and interpret the image of the world around us. Animal visual perception is a subject of great fascination to researchers, clinicians and animal owners. Unfortunately, we can neither tell exactly what an animal sees because they usually cannot tell, nor do we know precisely what there is to see because of the limitations of our own visual system.
