FIG. 5.

Lack of overt neuropathology in the BLA after diffuse traumatic brain injury. (A) Images of the BLA in de Olmos silver stained sections in sham, PID1, PID7, and PID28 animals (20 × magnification; scale bar = 50 μm). (B) Quantification of silver staining indicates no detectable differences in neuropathology between sham and injured animals over time post-injury (n = 4/PID; all bar graphs represent the mean ± standard error of the mean). (C) Montages of silver stained coronal sections from a representative sham and PID7 animal. Bilateral neuropathology in the cortex, hippocampus, thalamus, corpus callosum, and internal capsule by PID7 can be visually detected in comparison to the same region in the sham control. At 7 days post-injury, staining in the BLA (triangles) is similar to sham. BLA, basolateral amygdala; PID, post-injury day.
