PSYC 360 Lecture : Retinotopic Organization
Document Summary
Higher response (receptive field respond with much greater response if that contrast of simple cortical cell is part of a larger scene as opposed to a single stimuli) Decrease in contrast leads to increase in size of rf [malleability of rf - as content changes, rf changes (size/shape changes)] Malleability of a function of contrast of the input. Iso-orientation surround suppression: crf in a simple cortical cell. If place stimuli outside of crf is maximal to that crf, suppresses response inside that crf. If wavelength is critical to determine color, then color of shirt should change dramatically due to changes in wavelength when you leave indoors to go outside. Major problem for color vision explanation: single wavelength. Video: edwin land"s mondrian experiments, squares of color w/ identical radiated wavelengths yield very different color, named after paintings of piet mondrian perceptions.
