Document Summary
Extrastriate cortex (a set of visual areas so called because they lie just outside the v1) Regions just beyond v1 (such as v2), receptive fields begin to show an interest in properties that will be important for object perception. Might respond to dark edge of an object, but not to a dark edge created by a light object on a dark background. Processing information relating to location of objects in space and the actions required to interact with them (moving the hands, eyes, etc. ) Locus for the explicit acts of object recognition. Receptive field gets bigger as we move down into the temporal lobe. What is in view = more important than where it is. Could see but did not know what they were seeing (agnosia psychic blindness) Cells in it cortex have receptive fields that could spread over half or more of the monkey"s field of view.
