Immobility, swimming and climbing behaviors quantified during a 5 min swim in 19 °C water. A) Prior escapable or inescapable stress treatment resulted in very different behavioral topography in 5 min swim. Compared to stress-naïve (HC) rats, ES led to relatively more immobile postures, while IS reduced immobility. This trend is reflected as increases in active swimming and climbing behaviors in the IS group. Immobility, swimming and climbing were subsequently analyzed across the 5 min test. B) IS has reduced im-mobility as compared to HC and ES rats in the 3rd minute of the test while ES subjects spent more time in immobility in the last minute. C) ES rats spent less time swimming throughout the test and less time (D) climbing upon initial exposure. These data are shown for illustration; statistical comparisons are described in the text.
