Document Summary
The primary function of the sense organs is to provide information to guide behaviour. In terms of vision or brain receives fragments of information from approximately 1 million axons in each of the optic nerves. It combines and organizes these fragments into perceptions of a scene- objects having different forms, colours and textures, residing at different locations in a three dimensional space. Even when our bodies or our eyes move, exposing the photoreceptors to entirely new pattern of information, our perception of the scene does not change at all. We see a stable world, not a moving one, because the brain keeps track of our own movements and those of our eyes and compensates for constantly changing patterns of neural firing that these movements cause. Perception- the process by which we recognize what is represented by the information provided by the sense organs. This process gives unity and coherence to this input. We don"t see an object and perceive it.
