RAC1 and Anxiety: Expression of Rac1-N17 in WT mice had no effect on social recognition memory in the three-chamber (Figures 7A–C) or the five-trial test (Figures 7D,E), or locomotor activity in the open field test (Figures 7F–I), but reduced anxiety-like behavior in the elevated plus maze in WT mice (Figures 7J–N).
