Astrocyte coverage of large and medium sized parenchymal vessels in control and blast-exposed animals euthanized 6 weeks after exposure. Brain sections of five control and five blast-exposed animals were immunostained for collagen IV (green) and GFAP (red). a-e Representative images in the prelimbic cortex from each individual control animal. f-j Representative images in the prelimbic cortex from each individual blast-exposed animal. Arrows in panels (a, d, g) and (j) indicate areas of perivascular GFAP expression in regions of blood vessels that stain poorly for collagen IV. Scale bar, 20 μm
