Sex Differences and Gray Matter Psych of Sex Differences 310/ Mills Elizabeth Ducksworth Lauren Frazier John Liggins
Men have more gray matter in: • Midbrain • Left inferior temporalgyrus • Right occipital lingual gyrus • Right middle temporal gyrus • Both cerebellar hemispheres Brain Differences Chen, X., Sachdev, S. P., Wen, W., Anstey, J. K. (2007) Sex differences in regional gray matter in healthy individuals aged 44–48 years: A voxel-based morphometric study, NeuroImage, Volume 36, Issue 3, 691-699.
Women have more gray matter in: • Dorsal anterior • Posterior and ventral cingulate • Cortices, and right inferior parietal lobule Brain Differences (cont.) Chen, X., Sachdev, S.

The people whose information was selected to be thrown out happened to be less educated than the others • Used participants between the ages of 44 – 48 ( perhaps they believed that this age group was at the most stable level of brain development) • Men have more gray matter in their midbrains and cerebellum Interesting Points Chen, X., Sachdev, S. P., Wen, W., Anstey, J. K. (2007) Sex differences in regional gray matter in healthy individuals aged 44–48 years: A voxel-based morphometric study, NeuroImage, Volume 36, Issue 3, 691-699.
There was no mention of cross – cultural consistency • Changed MRI scanners in the middle of the study • The use of different scanners was included in the model as a covariate although the scanners use was shown to have no effect on brain volumes Critical Comments Chen, X., Sachdev, S.
