FIG. 4.

Diffuse traumatic brain injury transiently increases activated astrocytes in the BLA. (A) GFAP staining increases and astrocyte morphology changes indicate activated astrocytes. Representative images are presented at 40 × (scale bar = 40 μm) and 63 × (scale bar = 20 μm). (B) Quantification of GFAP staining shows a significant difference between PID1 and PID7 compared to sham (sham = 4; PID1 = 6; PID7 = 4, and PID28 = 4; data are represented as mean ± standard error of the mean). BLA, basolateral amygdala; GFAP, glial fibrillary acidic protein; PID, post-injury day.
