Total 20 h REM parameters for handling control (HC), ICV microinjections of saline prior to escapable shock (SAL-ES), corticotropin releasing factor prior to ES (CRF-ES) and astressin prior to ES (AST-ES). A. total REM. B. REM percentage (total REM time/total sleep time * 100). C. number of REM episodes. D. REM episode duration. Significant differences relative to CRF-ES: *p<0.05; **p<0.01; ***p<0.001. Significant differences relative to HC: +p<0.05; **p<0.01 (Tukey test). Values are means ± SEM.
