“…Even if the spatial relation between the facial contour and features was intact, the configural distortion may engage additional analytic processing of face perception in the IT area. However, the amplitudes at T5 and T6 electrodes were larger for Inverted and Scrambled than for Upright, although there were no significant differences among Upright, Inverted and Scrambled, different from previous N170 studies (George et al 1996;Rossion et al 2003). Therefore, we considered that amplitude differences among Upright, Inverted and Scrambled conditions were weak compared with previous ERPs, probably because of a latency jitter between trials and/or subjects, although this cannot be confirmed from the present study.…”

“…For example, activities in the primary visual areas are evoked by the change in luminance, regardless of the stimulus shape. (2) The generator source of N170 has not yet been confirmed, although some regions such as the superior temporal sulcus (STS), inferior temporal (IT) area, and other surrounding regions are candidates, as reported in previous studies (Bötzel et al 1995;Herrmann et al 2005;Itier and Taylor 2004c;Mnatsakanian and Tarkka 2004;Pizzagalli et al 2002;Rossion et al 2003;Schweinberger et al 2002;Shibata et al 2002;Taylor et al 2001;Watanabe et al 2003); however, N170 could be contaminated with activity generated in the primary visual cortex, as described above. The source of M170 in previous MEG studies is considered to be only the IT area, since only the tangential dipole can be recorded by MEG (Deffke et al 2007;Halgren et al 2000;Linkenkaer-Hansen et al 1998;Sams et al 1997;Swithenby et al 1998;Tanskanen et al 2005;Watanabe et al 1999a, b).…”

Effect of configural distortion on a face-related ERP evoked by random dots blinking

et al. 2008

Using random dots blinking (RDB), which reflects the activity of the higher visual area related to face perception, the following stimuli were presented. (1) Upright: a schematic face; (2) Inverted: the Upright stimulus inverted; and (3) Scrambled: the same contour and features as in Upright but with the spatial relation distorted. Clear negative components (N-ERP250) were identified at approximately 250 ms after stimulus onset. At the T5 and T6 electrodes, the peak latency was significantly longer for Inverted and Scrambled than for Upright. At the P4 electrode, the maximum amplitude was significantly larger for Scrambled than for Upright and Inverted. These results indicate that the delayed latency for Inverted and Scrambled reflects the involvement of the additional analytic processing caused by the configural distortion, and that the increase in amplitude for Scrambled indicates the existence of further processing caused by the distortion of the spatial relationship between the contour and features.

“…Therefore, these low-level perceptual factors should be controlled in studies of number evoked brain activity. Second, the dissociable data pattern of our electrophysiological results on the N170 and VPP components is contradictive with the N170/VPP association hypothesis (Joyce & Rossion, 2005;Rossion et al, 2003). Finally, most importantly, based on the present symbolic effect, it still cannot be decided whether the effect of symbolic type in VPP latency should be due to differential neural processing with respect to notation-specific identification processing or other subsequent processes.…”

“…We had two main hypotheses: first, we reasoned that if the distance effect in the P2p time window reflected the early number-specific processing, the numerical distance should not affect the ERPs during the N170 time window (e.g., N170 and VPP). Second, we expected that if the N170 and VPP elicited by numbers are manifestations of the same neural generators (Joyce & Rossion, 2005;Rossion, Joyce, Cottrell, & Tarr, 2003), then they should present identical functional response. In order to test these two hypotheses, we attempted to determine the time range in which number-magnitude representation is accessed, with an emphasis on these early components (e.g., N170 and VPP).…”

a b s t r a c tThis study investigated the influence of the symbol type and numerical distance of numbers on the amplitudes and peak latencies of event-related potentials (ERPs). Our aim was to (1) determine the point in time of magnitude information access in visual number processing; and (2) identify at what stage the advantage of Arabic digits over Chinese verbal numbers occur. ERPs were recorded from 64 scalp sites while subjects (n = 26) performed a classification task. Results showed that larger ERP amplitudes were elicited by numbers with distance-close condition in comparison to distance-far condition in the VPP component over centro-frontal sites. Furthermore, the VPP latency varied as a function of the symbol type, but the N170 did not. Such results demonstrate that magnitude information access takes place as early as 150 ms after onset of visual number stimuli and the advantage of Arabic digits over verbal numbers should be localized to the VPP component. We establish the VPP component as a critical ERP component to report in studies of numerical cognition and our results call into question the N170/VPP association hypothesis and the serial-stage model of visual number comparison processing.

“…The amplitudes of the N170 have been found to be approximately symmetrical (Rossion et al, 2003), despite the well-known differential involvement of both hemispheres in face processing (reviewed in Damásio et al (1990)). We hypothesize that patients with inferior occipital epileptic foci will show a smaller N170 in the affected hemisphere when compared with the spared one and that the resulting inter-hemispheric asymmetry will provide useful neurophysiologic information about the localization of epileptic foci involving the inferior part of the occipital lobes.…”

a b s t r a c tObjective: Localizing epileptic foci in posterior brain epilepsy remains a difficult exercise in surgery for epilepsy evaluation. Neither clinical manifestations, neurological, EEG nor neuropsychological evaluations provide strong information about the area of onset, and fast spread of paroxysms often produces mixed features of occipital, temporal and parietal symptoms. We investigated the usefulness of the N170 event-related potential to map epileptic activity in these patients. Methods: A group of seven patients with symptomatic posterior cortex epilepsy were submitted to a high-resolution EEG (78 electrodes), with recordings of interictal spikes and face-evoked N170. Generators of spikes and N170 were localized by source analysis. Range of normal N170 asymmetry was determined in 30 healthy volunteers. Results: In 3 out of 7 patients the N170 inter-hemispheric asymmetry was outside control values. Those were the patients whose spike sources were nearest (within 3 cm) to the fusiform gyrus, while foci further away did not affect the N170 ratio. Conclusions: N170 event-related potential provides useful information about focal cortical dysfunction produced by epileptic foci located in the close neighborhood of the fusiform gyrus, but are unaffected by foci further away. Significance: The N170 evoked by faces can improve the epileptic foci localization in posterior brain epilepsy.
