Visual mismatch negativity: a predictive coding view
An increasing number of studies investigate the visual mismatch negativity (vMMN) or use the vMMN as a tool to probe various aspects of human cognition. This paper reviews the theoretical underpinnings of vMMN in the light of methodological considerations and provides recommendations for measuring and interpreting the vMMN. The following key issues are discussed from the experimentalist's point...
متن کاملThe visual mismatch negativity is sensitive to
We investigated the sensitivity of visual mismatch negativity (vMMN) to an abstract and nonsemantic category, the vertical mirror symmetry. Event-related potentials were recorded to random and symmetric square patterns, delivered in passive oddball paradigm (participants played a video game). In one of the conditions, symmetric patterns were frequent (standard) stimuli and the random patterns w...
متن کاملOblique effect in visual mismatch negativity
We investigated whether visual orientation anisotropies (known as oblique effect) exist in non-attended visual changes using event-related potentials (ERP). We recorded visual mismatch negativity (vMMN) which signals violation of sequential regularities. In the visual periphery unattended, task-irrelevant Gábor patches were displayed in an oddball sequence while subjects performed a tracking ta...
متن کاملThe visual mismatch negativity elicited with visual speech stimuli
The visual mismatch negativity (vMMN), deriving from the brain's response to stimulus deviance, is thought to be generated by the cortex that represents the stimulus. The vMMN response to visual speech stimuli was used in a study of the lateralization of visual speech processing. Previous research suggested that the right posterior temporal cortex has specialization for processing simple non-sp...
متن کاملMismatch negativity
New perspectives in cognitive1,2 and clinical3,4 neuroscience have been opened up with the recent discovery of mismatch negativity (MMN),5 an auditory event-related brain potential (ERP) elicited by infrequent deviant sounds occurring in a sequence of repeated tones.1 The MMN appears as a negative displacement on the ERP to deviant sounds relative to that to standard sounds, with a peak latency...
