Behavior during cold swim stress. Behavior of rats during the 10-min cold swim procedure in Experiment 3. Rats were exposed to home cage control conditions (HC, N = 16) or inescapable tail shock (IS, N = 16) on Day 1. On Day 2, half of the rats of each treatment group were exposed to cold swim for 10 min in 15 °C water (HC/Swim, n = 8; IS/Swim, n = 8) while the other half remained in their home cages. The percent time spent climbing, swimming or immobile is shown. No difference was detected in the number of dives. ##p < .01 vs. HC/Swim group (Student's t-test for independent samples).
