Figure 6.

Rendered images of voxel-wise significance values (−log₁₀p-value × sign(t)) for the covariate “Gender” from pooled regression (Top) and single-shot regression (Center) and multi-shot regression (Bottom) overlaid on MNI average template. It can be seen from all the three rendered images that there is a significant amount of gray matter reduction in the sub-cortical regions for males. Since we are using unmodulated gray matter maps, these sex differences could be due to changes in brain volumes.
