FIG 6. Correlations between the regional AR of the corpus callosum and the ACV of the frontal areas. The AR in the anterior corpus callosum is strongly correlated with the frontal ACVs (superior frontal: r = .86, P < .0001; inferior frontal: r = .79, P < .0005). However, there are insignificant trends toward correlation between the AR in the anterior corpus callosum and the frontal ACVs within the patient group.

Left upper, anterior corpus callosum versus superior frontal region.

Right upper, anterior corpus callosum versus inferior frontal region.

Left lower, posterior corpus callosum versus superior frontal region.

Right lower, posterior corpus callosum versus inferior frontal region.
