Effects of EGCG treatment on Y maze and novel object recognition memory of Dp16(1)Yey mice. Y maze tests and Novel object recognition memory tests were performed on control wildtype (WT) (n = 14) and Dp16(1)Yey transgenic (TG) (n = 11) and treated WT (n = 16) and TG (n = 8) mice at the end of T1 treatment (P90). (A) Alternation performance in a Y-maze test. (B) Recognition index between familiarisation phase. (C) Quantification of videotracked distance mice travelled on the first day during habituation to the arena for 30 min. (D) Recognition index for mice exploring novel and familiar objects during the second day of novel object recognition memory tests. Recognition index (RI) was defined as RI = (exploration timenovel objects − exploration timefamiliar objects)/(exploration timenovel objects + exploration timefamiliar objects). Analysis of exploration time was performed during 12 min; Two ways ANOVA were performed followed by an Holm–Sidak multiple comparison procedure with *p < 0.05.
