Percent differences between left and right volumes.

Bars represent the differences between left and right volumes, expressed as percentages of the average size of the regions, calculated by $\frac{\left|\mathit{left\; volume}-\mathit{right\; volume}\right|}{\frac{\mathit{left\; volume}-\mathit{right\; volume}}{2}}\ast 100\frac{\left|\mathit{left\; volume}-\mathit{right\; volume}\right|}{\frac{\mathit{left\; volume}+\mathit{right\; volume}}{2}}\ast 100$. 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 = 0.05/7 = 0.007).
