FIGURE 2.

Behavior in elevated plus maze and open field test. Group housed mice from Experiment 2 were tested in the elevated plus maze (A). No differences were observed the percent of arm time spent in the open arm (A, left half) or latency to first entry in the open arm (A, right half). Single and group housed mice in Experiments 1 and 3, respectively, were tested in the open field (B,C). Neither salt nor housing condition significantly affected overall locomotor activity, measured as distance traveled (B), though a non-significant trend for a main effect of housing was noted (p = 0.085). There was a significant main effect of housing on the percent of total distance traveled in the center (C, ^∗p = 0.013). Individual data points are shown, with means indicated by horizontal lines, and 95% CI indicated with vertical lines.
