Percent differences between males and females.

Bars represent the differences between volumes for men and women, expressed as percentages of the average size of the regions, calculated by $\frac{\left|\mathit{male}-\mathit{female}\right|}{\frac{\mathit{male}-\mathit{female}}{2}}\ast 100\frac{\left|\mathit{volume\; male}-\mathit{volume\; female}\right|}{\frac{\mathit{volume\; male}+\mathit{volume\; female}}{2}}\ast 100$. Negative percentage differences correspond to larger right volumes, positive percent differences correspond to larger left volumes.

Black bars indicate a significant corresponding t-test for absolute volume differences at p < .001 (Bonferroni-corrected α = 0.05/8 = 0.006).
