PSYC 4031 : Perceiving And Recognizing Objects
Document Summary
A cell will respond to its preferred stimulus only if stimulus is presented in a very specific location relative to the point where the observer is fixating its gaze. The extrastriate cortex is a set of visual areas so called because they lie just outside the primary visual cortex. The visual system has many different problems to solve- like the problem of face processing- and it appears to have modules that are specialized for working on different problems. Retinal ganglion cells and lgn = spots. Clearly our brains are doing something pretty sophisticated beyond v1. 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 the pathway are important relating to the location of objects in space and the actions required to interact with them (moving the hands, eyes). This pathway is known as the where pathway.
