Title: Phantom Forms in Amblyopic Vision and what they reveal about the Generative Brain

Abstract: What we see is generated by our cortical neurons processing sensory input. Amblyopia provides a perfect case for studying the neural generation of percepts because many amblyopes see phantom forms through their amblyopic eye but not through the fellow eye. In amblyopic children, one eye generates weaker signals, leading to different cortical development for the two eyes. We picture these phantom forms and use them to mathematically derive transformations to normal cortical neurons that can generate the phantom percepts. These transformations can also explain other aspects of amblyopic vision, and the difference between the percepts generated by normal versus transformed neurons demonstrates the close link between neuronal properties and percepts.
