Sholl-analysis for intersections per 3 mm radial unit distance from sham-PSS, PSS +Saline, PSS + Hydrocortisone 25 mg/kg and PSS + RU486 30 mg/kg groups. Results displayed as mean ± S.E.M. (a) CA1 hippocampal subregion at day 8 post PSS-exposure: # Sham-PSS ≠ PSS-Saline-p < 0.025. * Sham-PSS, PSS-Hydrocortisone ≠ PSS-Saline, PSS-RU486-p < 0.015. ^^ PSS-Hydrocortisone ≠ PSS-Saline, PSS-RU486-p = 0.03. ** Sham-PSS ≠ PSS-Hydrocortisone-p < 0.04. @ PSS-RU486 ≠ Sham-PSS, PSS-Hydrocortisone p < 0.03 (b) CA3 hippocampal subregion at day 8 post PSS-exposure: * Sham-PSS ≠ PSS-Saline, PSS-RU486-p < 0.05. ** PSS-Hydrocortisone ≠ PSS-RU486-p < 0.05. @ PSS-Hydrocortisone ≠, Sham-PSS, PSS-Saline, PSS-RU486-p < 0.045. ^ PSS-Hydrocortisone ≠ PSS-Saline, PSS-RU486-p = 0.05. (c) DG hippocampal subregion at day 8 post PSS-exposure: * Sham-PSS ≠ PSS-Saline, PSS-RU486-p < 0.04. # Sham-PSS ≠ PSS-Saline-p < 0.02.
