  1. P-tau Thr181 were measured for the same rats studied in Table 3 at 40 weeks after blast exposure [21] and correlated with total time on the light side or total distance moved on the light side in a light dark escape task tested at 29 weeks after blast exposure [80]. Five blast and five control animals were analyzed. Correlations with p values equal to or less than 0.05 are indicated in bold
