Document Summary
Psychology 1xx3 notes vision ii mar 1, 2010. Brain: place where visual perception all comes together is the brain. Visual system: comprised of a set of assembly lines. Areas along the visual pathways process parts of the visual input before sending those partially- processed bits of information on to the next set of areas down the line for further processing. Before reaching their respective hemispheres, the axons from the inner region of each retina, that is the region of the retina closest to the nose, have to cross over to the opposite hemisphere. The point at which the optic nerves from the inside of each eye crosses over to the opposite hemisphere is called the optic chiasm. After the optic chiasm, the information from each visual field arrives in the opposite hemisphere, at which point the optic nerve fibres split and travel along two pathways.
