The Effects of Early-Life Predator Stress on Anxiety- and Depression-Like Behaviors of Adult Rats

<table>Immobile time of rats in forced swim test in the long-term (30 days) after 2-week predator stress. The immobile time (floating without struggling) of stimulated WKY rats was significantly lower than that of the control WKY rats, while Wistar rats showed no changes between predator-stimulated and control groups. Note that control WKY rats showed significantly longer immobile time than control Wistar rats. Each bar indicates a group defined according to strains (Wistar rats and WKY rats) and predator exposure (red bar: Wistar rats; white bar: WKY rats; unshadowed bar: control group; shadowed bar: predator exposure). Values are shown as mean ± SEM. The results of<i> t</i>-test are shown. <svg height="13.95" id="M54" style="vertical-align:-0.30096pt" version="1.1" viewbox="0 0 66.324997 13.95" width="66.324997" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
