Figure 5. Environmental enrichment combined with voluntary exercise normalizes open field behavior three weeks after IFS.

Figure 5

EE/VE started 1 week after the IFS procedure. (A). A percentage relative to non-shocked animals of the distance moved in the open field arena during a 5 minute test period is shown. (B) EE/VE normalizes the freezing behavior of IFS-exposed animals. *p<0.05 compared to non-shock control group. &p<0.05, compared to the IFS group under standard housing conditions. Values represent mean ± SEM. Group sizes: non-shock n = 12, shock n = 12.
