Visual mismatch negativity is sensitive to symmetry as a perceptual category.

TL;DR: The results show that the memory system underlying vMMN is capable of coding perceptual categories such as bilateral symmetry, even if the stimulus patterns are unrelated to the ongoing behavior.
Oblique effect in visual mismatch negativity

TL;DR: Evidence that perception of change could be accomplished at significantly smaller thresholds, than what elicits vMMN is provided, as changes from cardinal orientations represent a more detectable signal for the automatic change detection system than changes from oblique angles.
Asymmetric effect of automatic deviant detection: The effect of familiarity in visual mismatch negativity.
TL;DR: The aim of the study was to investigate the effect of familiarity on the vMMN; there was no significant difference between the vMNNs elicited by the two orientations and the differences in vMMNs to И and N deviants are not attributable to the physical difference betweenThe N and N stimuli.

Mismatch Negativity Does Not Show Evidence of Memory Reactivation in the Visual Modality

TL;DR: The possibility of reactivation of the memory representation underlying visual mismatch negativity (vMMN) was investigated in a modified passive roving-standard paradigm and emergence of a positive component at an early latency range elicited by deviants was interpreted as an index of increased sensitivity to rare changes in sequences dominated by identical stimuli.
Automatic change detection in vision: Adaptation, memory mismatch, or both? II: Oddball and adaptation effects on event-related potentials.
TL;DR: This study compared the event-related potentials obtained in two different paradigms: a passive visual oddball paradigm and an adaptation paradigm and identified the later part of the oddball difference potential as the genuine visual mismatch negativity—that is, an ERP correlate of sequence violations.
