Websites from the book:

1. Webvision is essentially an online text covering numerous topics in vision.

   Photoreceptors, a part of that site, details the structure of rods and cones with high magnification images; some animations are also available.

2. Magic Eye has a collection of 3-D stereograms and an explanation of how they work. Eye Tricks also offers Stereograms, as well as Optical Illusions; illusions are more than entertainment because they demonstrate principles of visual processing.
    
3. Videos show the Argus II implantable retina; the surgery to implant the Argus (not for the squeamish); an Alpha IMS recipient describing what he sees; a blind man who “sees” using BrainPort, which transmits a video image to an array of electrodes on his tongue; and Corey Haas, whose improved vision allows him to live a normal life after gene therapy.
    
4.  Causes of Color is a well-designed site with numerous exhibits on color in the real world and sections on color vision.

   Colorblindness has very helpful information and illustrations, and the third page has an interactive demonstration of seven forms of color blindness. Neitzvision features color-blindness demonstrations and the research of Jay and Maureen Neitz, including a recent study in which inserting a human gene for the long-wave receptor turned dichromatic (red-green color-blind) monkeys into trichromats.

5. Sensation and Perception at Hanover College covers topics from receptive fields to illusions.
    
6. Faceblind is the website of prosopagnosia research centers at Dartmouth, Harvard, and University College, London. Prosopagnosia, at Wikipedia, features a rotating brain that provides a 3-D view of the fusiform face area’s location.
    
7. Blindsight: Seeing Without Knowing It is a Scientific American article with a fascinating video of a man using blindsight to walk down a hallway filled with obstacles.
    
8. Hearing Motion is a video about motion synesthesia research, and Exactly Like Breathing is a collection of interviews of synesthetes. Synesthesia is a Scholarpedia article written by two researchers, and Neurophilosophy has an article on the genetics of synesthesia and another on tactile-emotion synesthesia.
