The levels of essential elements—(A) magnesium, (B) zinc, and (C) selenium—in the tissue of the brain cortex before and after treatment are displayed in this figure. Results of the experiment have been expressed as mean SD. In this study, the Kruskal–Wallis one-way analysis of variance (ANOVA) statistical technique was employed, followed by Fisher’s least significant difference tests for applied analysis. Statistical difference is said to be significant at p < 0.05. α p < 0.05 vs. control group, *p < 0.05 vs. BI group, BI: Brain Ischaemia, VPA: Sodium Valproate.
