Document Summary

Primary function of senses is to guide behaviour. First level located in occipital lobe, surrounds primary visual cortex. Second level divided into 2 parts, one is middle of parietal lobe and one in lower part of temporal lobe. Knowledge of early stages of visual analysis comes from investigations of activity of individual neurons in thalamus and primary visual cortex. David hubel and torsten wiesel inserted microelectrodes into regions of visual system in anasthetized cats and monkeys (unconsious but visual system still active) to detect aps produced by individual neurons. Found place in visual field with most response and objects with most response. Found that surface of retina is mapped on surface of primary visual cortex centre of visual field is largest area. 2,500 blocks of tissue . 5x. 7 mm in size containing 15,000 neurons each, receiving information from same small region of retina, and thus small region of visual field (amount seen through soda straw)
