“…In a previous study using RDB ( Okusa et al, 1998 ; Okusa et al, 2000 ), a clear evoked component peaking at around 200–300 msec was identified. In this study ( Miki et al, 2009 ), we identified a component that had a peak deflection 200–300 msec after stimulus onset at T5 and T6 electrodes of the International 10–20 System in the left and right temporal areas, respectively. The peak latency when the amplitude of the component was maximal for each condition after the stimulus onset and the maximum amplitude of the component were individually measured within 300 msec.…”

“…In this review, we have introduced a series of previous EEG and MEG studies on human face perception and discussed the following characteristics of face perception processing: (1) the inferior temporal (IT) activity evoked by a face ( Watanabe et al, 1999a , b ), (2) the effects of face contours and features on processing for face perception ( Miki et al, 2007 ), (3) the effects of eye aversion on event-related potentials (ERPs) ( Watanabe et al, 2002 ), (4) face inversion effects and differences between the right and left hemispheres in face perception ( Watanabe et al, 2003 ; Miki et al, 2011 ), and (5) a useful visual stimulus method for investigating face perception ( Miki et al, 2009 ).…”

The face has a large amount of information that is useful for humans in social communication. Recently, non-invasive methods have been used to investigate human brain activity related to perception and cognition processes. Electroencephalography (EEG) and magnetoencephalography (MEG) have excellent temporal resolution and reasonably good spatial resolution. Therefore, they are useful to investigate time sequences of human brain activity related to the face perception process. In this review, we introduce our previous EEG and MEG studies of human face perception that demonstrated the following characteristics of face perception processing: (1) Event-related components in the temporal area related to the activity in the inferior temporal (IT) area, corresponding to the fusiform face area (FFA), are evoked approximately 180 msec after the presentation of a face. The activity in the IT area plays an important role in the detection processing of a face, and the contours of a face affect the activity in the IT areas. (2) Event-related components in the temporal area related to the superior temporal sulcus (STS) activity are larger when eyes are averted than when directly looking into the eyes. (3) The direction of features of a face affects the face perception processing in the right hemisphere. On the other hand, the matching of the direction between the contours and features of a face affects the processing in the left hemisphere. (4) Random dots blinking (RDB), which uses temporal changes in patterns of many small dots to present stimuli without a change in luminance during the presentation of a face, is a useful visual stimulus method to investigate the brain activity related to face perception processing in the IT area using EEG and MEG.

The present study explored the time course of neighborhood frequency effect at the early processing stages, examining whether orthographic neighbors with higher frequency exerted an influence on target processing especially at the phonological stage by using the event-related potential (ERP). Thirteen undergraduate students were recruited in this study, and they were required to covertly name Chinese characters with or without higher-frequency neighbors (HFNs); meanwhile, their brain activity was recorded. Results showed that the effect of neighborhood frequency was significant in frontocentral P2 amplitude, with a reduction for naming characters with HFNs compared to those without HFNs; while there was no effect in posterior N1 amplitude. The only neighborhood frequency effect in P2 component suggested a special role for the HFNs in phonological access of Chinese characters. The decrease in amplitude for naming with-HFN characters might be associated with the phonological interference of higher-frequency neighbors due to their different pronunciations from the target characters.

We have been studying the underlying mechanisms of face perception in humans using magneto MEG and electro encephalography EEG and near infrared spectroscopy NIRS. With the presentation of both upright and inverted unfamiliar faces, the fusiform gyrus and the superior temporal sulcus were activated simultaneously, but independently, predominantly in the right hemisphere. Latencies with inverted faces relative to those with upright faces were longer in the right hemisphere and shorter in the left hemisphere. We consider that differences in processing upright versus inverted faces are attributable to temporal processing. When viewing the motion of the mouth and eyes, a large clear MEG component, 1 M mean peak latency of approximately 160 ms , was elicited to both mouth and eye movement, and was generated mainly in the occipito temporal border, at human MT V5. The 1 M to mouth movement and the 1 M to eye movement showed no significant difference in amplitude or generator location. Therefore, our results indicate that human MT V5 is active in the perception of both mouth and eye motion, and that the perception of movement of facial parts is probably processed similarly. We investigated the effects of subliminal stimulation on visible stimulation to demonstrate the priority of facial discrimination processing, using a unique, indiscernible, color opponent subliminal COS stimulation. We recorded MEG after the presentation of a face or flower stimulus with COS conditioning using a face, flower, random pattern, and blank. The COS stimulation enhanced the response to visible stimulation when the figure in the COS stimulation was identical to the target visible stimulus, but more so for the face than for the flower stimulus. We speculated that the enhancement was caused by an interaction of the responses after subthreshold stimulation by the COS stimulation and the suprathreshold stimulation after target stimulation, such as in the processing for categorization or discrimination. We recently measured NIRS in 5 8 month olds' left and right lateral areas while they were looking at faces. The results of our first study are summarized as follows 1 the concentration of oxyhemoglobin and total hemoglobin increased significantly in the right lateral area during the upright face condition, and 2 the concentration of total hemoglobin in the right lateral area differed significantly between the upright and inverted conditions. This is the first evidence showing that there is an inter hemispheric difference on the effect of face inversion in the infant brain using a hemodynamic method. After this report, we have reported face perception and recognition in infants using NIRS concerning profile face perception, scramble face perception, facial expression perception, adaption effect of face, face perception using point lights, mothers' face perception, and Arcimboldo's funny face perception.
