Experimental time line. BrdU administered 12-days before exposure to 6-blasts of 185 dB peak SPL. Forty-five days after the blast wave exposure rats were trained for 6-days on the MWM memory acquisition task followed 15-day later by a single probe trial on the memory retention task. A few day later, rats were evaluated with the EPM and OF tests. Several days later, the CAP was measured and immediately afterwards, the brain was perfused with fixative and subsequently processed for histological analysis of the hippocampus.
