Changes in ADC across nuclei between 2 and 4 weeks pre- and post-blast. A significant increase occurred in the MGB between 2 weeks pre- and post-blast, which remained significantly elevated through post-blast 4 weeks. 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.
