Changes in FA values across nuclei between week 2 pre- and post-blast. A significant increase occurred in the IC between week 2 pre- and post-blast. ANOVA and post-hoc Bonferroni tests.

MGB, medial geniculate body; ANOVA, analysis of variance; IC, inferior colliculus; CC, corpus callosum; AMG, amygdala; DCN, dorsal cochlear nucleus; SD, standard deviation; Pre, pre-blast; PBwk2, post-blast week 2; PBwk4, post-blast week 4.
