PSYB51H3 Chapter Notes - Chapter 4: Extrastriate Cortex, Temporal Lobe, Occipital Lobe
Document Summary
Extrastriate cortex: the region of cortex bordering the primary visual cortex and containing multiple areas in visual processing. These areas are named v2, v3, and so on. In the extrastriate regions just beyond v1 (like v2), receptive fields begin to show an interest in properties that will be important for object perception and recognition. V1 cell may respond same way to dark edge on dark object and dark edge created by light object on dark background but v2 cares about boundary ownership and won"t respond to the latter. From the extrastriate regions of the occipital lobe of the brain, visual information moves out along two main pathways: one pathway heads up into the parietal lobe. Visual areas in this pathway are important for processing information relating to location of objects in space and the actions required to interact with them (moving hands, eyes).
