"The Context of Early Vision"

The role of context in standard models of early vision is often incomplete. I will present experimental evidence (from fMRI) which highlights that even non stimulated areas of early visual cortex contain discriminating information about the surrounding context. I will suggest that these results demonstrate the ubiquitous role of context in the visual system, are compatible with a predictive coding or constructivist explanation of brain function, and that the paradigm offers a way to study contextual influences independently of bottom-up influences.
