	abstract = {In this study, we investigated whether the cognitive system, known to be able to register regular visual event sequences and the violation of these sequences automatically, had the capacity of processing two sequences simultaneously. To this end, we measured the visual mismatch negativity (vMMN) component of ERPs as interwoven event sequences simultaneously presented to the left and right side of the screen. One of the sequences consisted of geometric patterns (diamonds); the other, photographs of human faces. In successive cycles, parts of the stimuli vanished and then re-appeared (the OFF/ON method). The vanishing parts served as either standard (frequently vanishing parts) or infrequent (deviant) events, but these events were task-irrelevant. The 20 adult participants (age 21.40 ± 2.72 years) performed a visual tracking task, with the OFF/ON task being a passive oddball paradigm. According to the results, both OFF and ON events, and both diamond and face stimuli elicited the vMMN component, showing that the system underlying this activity is capable of processing two event sequences if the sequences consist of fairly different kind of objects as stimuli. The sLORETA analysis showed that the source of vMMN was more frequent contralaterally to the deviant event, and the sources comprised loci from ventral and dorsal structures, as well as some anterior loci.},

	abstract = {The detection of unattended visual changes is investigated by the visual mismatch negativity (vMMN) component of event-related potentials (ERPs). The vMMN is measured as the difference between the ERPs to infrequent (deviant) and frequent (standard) stimuli irrelevant to the ongoing task. In the present study, we used human faces expressing different emotions as deviants and standards. In such studies, participants perform various tasks, so their attention is diverted from the vMMN-related stimuli. If such tasks vary in their attentional demand, they might influence the outcome of vMMN studies. In this study, we compared four kinds of frequently used tasks: (1) a tracking task that demanded continuous performance, (2) a detection task where the target stimuli appeared at any time, (3) a detection task where target stimuli appeared only in the inter-stimulus intervals, and (4) a task where target stimuli were members of the stimulus sequence. This fourth task elicited robust vMMN, while in the other three tasks, deviant stimuli elicited moderate posterior negativity (vMMN). We concluded that the ongoing task had a marked influence on vMMN; thus, it is important to consider this effect in vMMN studies.},

	abstract = {There is general agreement that some of the generators of the visual mismatch negativity (vMMN) are found in modality-specific brain structures. However, the involvement of anterior structures is less clear. The inconsistent results may have been due to paradigms that could not distinguish between low-level stimulus adaptation and the genuine vMMN. In our study we used an experimental paradigm in which the unattended standard and deviant stimuli were the vanishing and appearing parts of a constantly present object. In this case mainly genuine vMMN is elicited to the vanishing deviants. The paradigm was modified for use in EEG and fMRI studies. In our ERP study vMMN to the vanishing deviant stimuli emerged in the 100-200 ms time window. VMMN was also observed to the appearing deviant stimuli in the 100-200 ms and in the ~230-280 ms time windows but with a different scalp distribution. The fMRI results indicated larger activity for the deviant stimuli compared to the standard stimuli at posterior, modality-specific brain areas, but no difference in the anterior activation. By contrast, the results from the source localization analysis of the EEG data indicated differences in anterior activation. We explore the reasons for this contradiction.},
