In addition, the change in encoding is sufficient to predict the behavioral characteristics of the tilt illusion using a Bayesian observer model. (4/6)

With an oriented surround, encoding precision is locally increased for stimuli similar to the surround orientation, specifically in higher areas of the visual cortex. This encoding change also reflects the surround-conditioned orientation statistics in natural scene. (3/6)

We measured sensory encoding precision (in terms of Fisher information) from both behavioral and neural data in an orientation estimation task. At baseline, encoding reflects the natural scene statistics of orientation. (We observe the cardinal bias in different parts of the visual cortex!). (2/6)
