Face coding is bilateral in the female brain.

<h4>Background</h4>It is currently believed that face processing predominantly activates the right hemisphere in humans, but available literature is very inconsistent.<h4>Methodology/principal findings</h4>In this study, ERPs were recorded in 50 right-handed women and men in...

Results showed no sex difference in the amplitude of N170 to objects; a much larger face-specific response over the right hemisphere in men, and a bilateral response in women; a lack of face-age coding effect over the left hemisphere in men, with no differences in N170 to faces as a function of age; a significant bilateral face-age coding effect in women.<h4>Conclusions/significance</h4>LORETA reconstruction showed a significant left and right asymmetry in the activation of the fusiform gyrus (BA19), in women and men, respectively.
