Predictive Localization in the Visual System
To overcome neural processing delays in sensory pathways and to enable successful interaction with objects in a dynamic world the brain needs to predict the positions of moving objects. I will present evidence that moving objects are indeed perceived in predicted positions. Psychophysical experiments show clear forward shifts of moving objects from their retinal positions. In fMRI experiments I showed that these predictive position shifts can be measured in motion-sensitive retinotopic areas of visual cortex. TMS over these areas interferes with the perception of predicted positions. Recent results from patients with cerebellar atrophy show that the predictive circuitry of the cerebellum might also be involved in perceptual predictions.
