A) Curiosity levels of non-Tg and mThy1-hAβPP751 Tg mice expressed by the number beam breaks by nose or paw poking into the holes during a ten-minutes trial, at 3, 6, and 9 months of age. B) Gender stratification of the mThy1-hAβPP751 Tg mice at 3, 6, and 9 months of age. Data are represented by means ± SEM. * Indicates a significant difference between non-Tg and mThy1-hAβPP751 Tg mice with p<0.05 by one-way ANOVA ** Indicates a significant difference between non-Tg and mThy1-hAβPP751 Tg mice with p<0.01 by one-way ANOVA.
