Document Summary
Primary function of sense organs is to provide information to guide behaviour. Perception: a rapid, automatic, unconscious process by which we recognize what is represented by the information provided by our sense organs. Visual perception by the brain is often described as a hierarchy of information processing. According to this scheme, circuits of neurons analyze particular aspects of visual information and send the results of their analysis to another circuit, which performs further analysis. Eventually this process leads to perception of the scene and all objects in it. Our knowledge of the earliest stages of visual analysis has come from investigation of the activity of individual neurons in the thalamus and the primary visual cortex. David hubel and torsten wiesel inserted microelectrodes into various regions of the visual systems of cats and monkeys to detect the action potentials produced by individual neurons.
