Outline of Final Research Achievements

The previous studies have shown that the 2 neural routes are important for facial recognition of strangers; the fusiform gyrus for person identity and the amygdala for facial expression. These studies have examined the face recognition of strangers, but it was unknown whether the close relatives' face was processed by the two same routes.
Using functional magnetic resonance imaging (fMRI) with multi-voxel pattern analysis (MVPA), we clarified that the left fusiform gyrus is involved in both person identification and recognition of facial expressions of close relatives.
Therefore, in facial recognition of close relatives, the conventional face cognitive model do not apply. We propose a new model for recognition of close relatives' face; an one route model.
