| Outline of Final Research Achievements |
Our aim was to elucidate the neural mechanisms of unconscious face processing by using magnetoencephalography (MEG). We used the two different visual stimuli: one was subliminal (Sub) presentation of the face (16 ms) and the other was onset binocular rivalry (ON-BR). Sub did not induce the significant activations of the primary visual cortex. However, ON-BR showed the significant effect on the right fusiform face area (FFA). We did not detect the M170 when the face image was suppressed, although this component was clearly present when awareness for the face was initiated. We also found a significant difference in the latency of the M170 (human < monkey < house). Taken together, our findings indicate that face stimuli are imperative for evoking the M170 and that the right FFA plays a critical role in human face awareness. Therefore, unconscious face processing is generated in the right FFA.
