Correlations between p-tau Thr181 levels with freezing in the cued phase of a fear-conditioning paradigm. P-tau Thr181 levels were previously determined by Western blotting with the antibody AT270 [21] in the left anterior cortex (a), right anterior cortex (b), and right hippocampus (c) at 40 weeks after blast exposure. Levels were correlated with freezing to the second tone in the cued testing phase of a fear learning task previously found to be affected in the same blast-exposed rats at 35 weeks following blast exposure [80]. Panel d presents the correlation between total tau in the right amygdala and freezing. Five blast and five control animals were analyzed. Kendal's tau-b correlation coefficients and p values are indicated
