In Experiment 4 animals were first sham operated (sham) or adrenalectomized (ADX) and replaced with subcutaneous corticosterone pellets, then were either undisturbed until restraint on day 5 (acute restraint) or given 4 days of repeated forced swim prior to restraint on day 5 (swim + acute restraint). A. Graphs show total time spent immobile, lightly mobile, and strongly mobile (struggling) in sham and ADX animals during 30 minute restraint on day 5. B. Timecourse of time spent strongly mobile (struggling) across 30 minute restraint on day 5, divided by both stress history and by surgery. All data are expressed as mean ± SEM. Asterisks indicate overall repeated swim + restraint group values significantly different from overall acute restraint values.
