Changes in RD across nuclei between pre- and post-blast weeks 2 and 4. No significant changes in RD were found in either the auditory or non-auditory structures. 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.
