Expectation suppression in early visual cortex depends on task set

This is an fMRI dataset that was collected in human participants while we manipulated the predictability of visual stimuli in the periphery. Participants were presented with either predictable or non-predictable visual stimuli while they performed three tasks that differently engaged cognitive resources. We analyzed the BOLD response of voxels in early visual cortex (V1-V3) to investigate whether the effect of expectation on sensory processing was modulated by task set. We also performed a whole-brain analysis. A full account of the paradigm and analyses can be found in the file 'Materials and Methods'.
