Sex differences in callosal transfer and hemispheric specialization for face coding

► ERPs were recorded in 16 men and 17 women during a sex face coding task. ► IHTT was faster in the LVF/RH→LH than in the RVF/LH→RH direction, only in men. ► IHTT was faster and symmetrical in women. ► A possible relation may exist between asymmetrical IHTT and brain asymmetry.
