Document Summary
Brain plasticity: inverted image on retina is interpreted right side up, Brain can adapt to seeing the world differently it will eventually be right side up again. Mind is filing in the space where there is this visual input. Brain thinks there is only one light source. Interpret some spheres as 3d, some as cavities. Brain is following a rule, following a single light source. If a person has damage on primary visual cortex it will have an impact on what they will see. Eyes were functioning but primary visual cortex was destroyed. Flashed different types of faces- flashed a scary face, if he were really blind he wouldn"t flinch, but he flinched every time. Had no idea what was being flashed but had a reaction to it. Walked through a hallway and was able to avoid objects, but could not say what they were. Info travels to primary visual cortex but also to the superior colliculus.
