Low-level blast exposure disrupts gliovascular and neurovascular connections and induces a chronic vascular pathology in rat brain

Lack of overt histopathology in the brain at 6 weeks after the last blast exposure. a-d Sections from control (a, c) and blast-exposed (b, d) animals were stained with hematoxylin and eosin. Rats were euthanized 6？weeks after blast exposure. Higher power images of the frontal motor cortex are shown panels (c) and (d). Scale bars, 500？μm (a, b); 40？μm (c, d
