In this functional magnetic resonance imaging study we tested whether the predictability of stimuli affects responses in primary visual cortex (V1). The results indicate that evoke smaller V1 when their onset or motion direction can be predicted from dynamics surrounding illusory motion. We conclude finding human brain anticipates forthcoming sensory input allows predictable to processed with less neural activation at early stages cortical processing.
