Figure 2. Anxiety-like behavior in the elevated plus maze.

PPS animals spent more time in the closed arms of the maze, and less time in the center and open arms as compared to CTRL (A). In addition, they spent less time head-dipping and stretching and more time self-grooming than CTRL (B). * p<0.05, ** p<0.01 versus CTRL; results are the mean ± SEM.
