Amyloid β Enhances Typical Rodent Behavior While It Impairs Contextual Memory Consolidation

Figure 6

Aβ induces mild anxiety. (a)–(f) Quantifications of anxiety-related behaviors evaluated during the 5 min test in the open field arena. Such measurements included (a) the distance traversed; (b) the time spent in the arena’s center; (c) the defecation frequency; (d) the amount of rearing; (e) the time spent grooming and (f) freezing. Note that the only parameter that significantly increased in Aβ-treated animals is the duration of the freezing behavior. Data are presented as means ± S.E.M. versus Ctrl.
