PSYB51H3 Lecture 4: Chapter 4
Document Summary
Beyond v1 is the extrastriate cortex: a region of cortex bordering the primary visual cortex and containing multiple areas involved in visual processing. In a monkey, its called v2 and v3 and so on. The visual system has many different problems to solve and it appears to have modules that are specialized for working on different problems. In the extrastriate regions just beyond v1, receptive fields begin to show an interest in properties that will be important for object perception. From the extrastriate regions of the occipital lobe of the brain, visual information moves out along two main pathways. One pathway (aka the where pathway) heads up into the parietal lobe: deployment of attention. Visual areas in the where pathway seem to be important for processing information relating to the location of objects in space and actions required to interact with them.
