We make predictions about eye of origin of visual input: Visual mismatch negativity from binocular rivalry

The visual mismatch negativity (vMMN) is a negative deflection in an event-related potential (ERP) between 200 and 400 ms after onset of an unpredictable stimulus in a sequence of predictable stimuli. Binocular rivalry occurs when one image is presented to one eye and a different image is presented to the other. Although the images in the two eyes are unchanging, perception alternates unpredictably between the two images for as long as one cares to look. Binocular rivalry, therefore, provides a useful test of whether the vMMN is produced by low levels of the visual system at which the images are processed, or by higher levels at which perception is mediated. I will review research showing that a vMMN occurs when rival images are swapped between the eyes. This is interesting and important because we cannot tell which eye is viewing which image, showing that we make predictions about visual input of which we are not aware.
