The paper investigates how visual surprise interacts with the visual cortex by analyzing EEG data from humans viewing changing visual attributes, finding attribute-dependent temporal hierarchies in whole-brain prediction error responses.

This study investigates onset primacy in visual change detection using event-related potentials, finding that onsets are detected faster and evoke larger P300 responses than offsets.

This study examines how prediction and attention modulate visual perception by analyzing ERP components N170 and N2pc in response to predictable and unpredictable visual trajectories.

The paper identifies double dissociations in prediction-error signals for face identity and head orientation violations in dorsal and ventral visual streams using MEG.

The paper investigates how the brain responds to prediction errors in visual stimuli using EEG and MEG, finding that the N/M170 signal reflects mismatches between predicted and actual visual inputs.
