Interquartile values of MIFA, MIRD and MIAD by fiber group.

Fiber Group MIFA MIRD MIAD
Commissural** .01/.18/.32† .20/.34/.49 .23/.49/.73†
Association* −.04/.14/.28† .11/.21/.33† .11/.23/.41
Limbic** −.15/.04/.19 .10/.25/.44† .17/.39/.60†
Projection** −.42/−.03/.20 −.26/.03/.27 −.18/.16/.47

The statistics for MI are shown using the interquartile range, 25/50/75. Commissural fibers had the largest MI and projection fibers had the lowest, with association and limbic fibers in the middle. The order of microstructural MI is retained in all fiber groups. *, ** denote fiber group retained MIFA<MIRD<MIAD within the fiber group at a minimum pairwise significance of p<.005, or p<10−10, respectively. Each microstructure MI had a pair of fiber groups that were not significantly different (two sample t-test, p>.05), these pairs are denoted with a †. All other pairs were significant at p<.05.
