TNF-α level (in ng/g protein) in the prefrontal cortex a and hippocampus b, and caspase-3 level (in pg/g protein) in the prefrontal cortex c and hippocampus d of rats in the different studied groups. Data is expressed as Mean ± SD and analyzed by (one-way ANOVA), followed when significant by Post Hoc Test (Tukey). * p < 0.05, **p ≤ 0.001 significant difference compared to control group. #p < 0.05, ##p ≤ 0.001 significant difference compared to untreated chronic restraint stress group. CRS: chronic restraint stress, SeNPs: selenium nanoparticles, TNF-α: tumor necrosis factor alpha, PFC: prefrontal cortex, HPC: hippocampus
