Course explores how what we see is generated by the visual system. Students learn how the visual system links stimulus patterns with reproductive success without ever recovering real-world properties and without invoking feature detection, image representation in the brain, and probabilistic inference. Course considers in broader terms the relationship between the objective world and subjective human experience. Course delivered in flipped format with all lectures assigned as videos and class time devoted entirely to discussion of papers, problems and different perspectives on how the visual brain operates.
