Document Summary

Lens focuses light rays on retina, inverts whatever you are seeing. Takes all signals from retina to the brain. Three cells that make up the retina: ganglion cells, bipolar cells, visual processors: where the actual light is coming from. Cone: give you colour vision, allow you to see colour. When light hits the rods and cones it starts/stops them from ring and brain picks this up (neural impulses) Cortex is the part of the brain that helps us to understand things. Visual cortex takes stimuli (light) and turns it into shapes (process: feature detection) Individual cells in the cortex that respond to lines at various angles. Take the symbols of lines and create a pattern. !1 source: university of waterloo psychology 101 course online. Cells converge to create our perception of what we see. How the visual cortex organizes all this information is not yet completely understood. Two theories of colour vision and where it comes from.
