used, a similar but less widespread pattern of greater thickness in females was found, which was most pronounced in the left inferior and superior frontal gyri, and then to a lesser extent in the superior pre- and post-central regions and occipital lobe. In contrast, males had an area of increased thickness in the left posterior temporal lobe. Surface area was significantly larger in females when scaled data were used and was larger in males using the original unscaled data. Gyrification, measured through determining the degree of curvature at thousands of points across the brain, was higher in females in several regions in the frontal, parietal, and temporal lobes. The areas of greatest differences were in the anterior regions of the frontal lobe. No regions had greater gyrification in men(Luders et al., 2004; Luders et al., 2006).
