  1. P-tau Thr231 levels were previously determined by Western blotting at 40 weeks after blast exposure [21]. P-tau Thr231 levels were correlated with three behavioral parameters in the elevated zero maze (move distance, open arm time and cross arm latency) determined at 30 weeks following blast exposure [80]. Five blast and five control animals were analyzed. No values were statistically significant
