Description

<jats:title>Significance</jats:title><jats:p>Understanding the neural basis of face perception, arguably the most important visual function for human social ecology, is of the utmost importance. With an original fast periodic visual stimulation approach, we provide a comprehensive quantification of selective brain responses to faces throughout the ventral visual stream with direct recordings in the gray matter. Selective responses to faces are distributed in the whole ventral occipito-temporal cortex, with a right hemispheric and regional specialization supporting two decades of indirect recordings of human brain activity in neuroimaging. We also disclose three distinct face-selective regions in the anterior temporal lobe, an undersampled region in neuroimaging, and reveal exclusive responses to faces at the neural population level in these regions.</jats:p>
