To examine the layer-dependent fMRI
responses of face processing in human visual cortex, we acquired submillimeter functional and
anatomical data at 7T. Here, we measured fMRI responses to left single and paired faces with various interstimulus
intervals; furthermore, we calculated the repetition suppression (RS) ratio
from three cortical layers in the right primary visual cortex (V1) and occipital face
area (OFA). The fMRI response and RS ratio of superficial and middle layers of the right V1 were similar to those of all right OFA layers. Hence, the layers in different hierarchical
visual areas were modulated in the same manner.
