Abstract

Magnetoencephalographic (MEG) auditory evoked fields produced by short tone pips were recorded from 34 normal adults (17 males, 17 females)and the 100 msec latency component (M100) localized in left and righthemispheres. Absolute M100 location in the antero-posterior dimensionwas calculated for each subject. M100 sources were significantly further anterior in the right hemisphere of males. Magnetic resonance (MR)based anatomy of the superior temporal gyri (STG) in a subset of 17 subjects showed that in the left STG of both males and females M100 sources were located approximately midway on the STG. In the right hemisphere of males, however, M100 sources were significantly further anterior on the STG than was the case for females. The findings are compatible with a sex based difference in right STG functional anatomy, with evidence of greater hemispheric lateralization in males compared to females based upon a predominantly right hemisphere contribution.
