Effect of post-exposure SD on relative prevalence rates according to CBC classification: top line: the behavioral procedure used for the unexposed and PSS-exposed rats. Vertical arrow represents total SD procedure. Post-exposure SD reduced the prevalence of PTSD-like behavioral responses (EBR) (a) relative to the exposed-untreated group and concomitantly increased the prevalence of minimal behavioral responders (b). No differences were observed in the prevalence of PBRs (c). CON, unexposed control; EBR, extreme behavioral response; MBR, minimal behavioral response; PBR, partial behavioral response; PSS, predator scent stress; SD, sleep deprivation.
