Is visual cortex more like chatGPT or a masked autoencoder? Come to my BCCN seminar tomorrow at 10am ET on zoom (or read the paper) to find out! #neuroscience

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

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).
