FIG. 7.

Representative silver degeneration-stained coronal brain sections from all three experimental groups: sham control (left) single blast exposed (center) and double blast exposed (right). Two coronal sections are shown for each group—one at the level of the dorsal hippocampus at approximately Bregma −3.3 mm (top), and one through the cerebellum at approximately Bregma −11.4 mm (bottom). Magnified insets are medium-high power micrographs (20×objective) of the cerebellar white matter showing silver staining of axons and the formation of axon retraction balls typical of those seen in traumatic axonal injury.
