Fig. 1.

BFT from all animal strains displayed as a clustered boxplot. Within each box on the boxplot, the solid horizontal line towards the middle of the box represents the median of the data set; above the line is the upper or third quartile and below the line is the first or lower quartile of that dataset. The maximum and minimum values (excluding outliers) are represented by the whiskers above and below the boxes. Outliers are represented by the circles and stars above the top whisker, as calculated by SPSS (although they were included in the statistical analysis). At 39 weeks of age, C56BL/6 mice took the shortest time to find the buried food compared to all other mice at that age (#p < 0.01). At 52 weeks of age, 3xTg-AD mice took significantly longer to find the buried food than all other mice at that age (##p < 0.001).
