Hematoxylin and eosin stained sections of brain cerebral cortex from (A) control, and low-intensity blast-exposed animals at (B) day 1 (C) day 4, and (D) day 7 after blast. Darkened and shrunken neurons evidenced by the presence of peri-somal spaces at day 1 post-blast compared to control and in lesser quantities at day 4 and day 7 post-blast. Vasculature appears to be narrowed in day 1 and day 4 post-blast compared to control.
