Mismatch responses were evoked by novel stimuli and by a uniform gray screen, but not by shuffling of the temporal order.
Mismatch responses were only observed when the input pattern to the RF was novel (i.e., not learned during training).

Does predictive coding work in SPACE or in TIME? Most neuroscientists assume TIME, i.e. neurons predict their future sensory inputs. We show that in visual cortex predictive coding actually works across SPACE, just like the original Rao+Ballard theory #neuroscience
