Transduction convert physical energy into electrical changes in nerve receptor cells: rods and cones are the receptor cells for visual system. Neural coding stimulus input must be coded for intensity and qualitative aspects. Interactivity : in time : color adapation, in space : contrast effects visual illusions. In vision, the response in one receptor region depends upon how neighboring receptor regions are responding: top down & bottom up interactions. 2 visual pathways: dorsal stream the where pathway, ventral stream what . Light is emitted from a light source and the light hits some distal stimulus ( a tree, a car, your bff) A photo chemical reaction takes place inside these cells when exposed to light. Packed around fovea daytime receptors ( h c: allow us to see in bright color, allow us to see fine spatial detail, allow us to see different colors.
