To elucidate the spatiotemporal dynamics of the processing of inverted human and animal faces, we recorded face-selective responses (M170) to upright and inverted human and monkey faces using a 306-channel whole-head magnetoencephalography.

Additionally, face orientation differentially modulated the anterior region of the fusiform gyrus (FG) in both face categories.
