Generative Phenomenology of form perception: Perceptograms and cortical models for amblyopic phantom percepts.

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 (Generative Phenomenology) because many amblyopes see phantom forms that contain more features than the stimulus through their amblyopic eye (AE) but not through the fellow eye (FE). Seeing phantom forms is unlike most visual disorders that lead to deficits and requires different types of models. Using computer guided dichoptic displays, we acquired perceptograms (viewable records of perceived images) for single gratings shown to AE. 92.6% of phantom percepts were matched exactly by plaid patterns made of two gratings shown to FE. A formal equation between the cortical signals generated by the gratings seen through AE with the signals g
