GFAP and Stroke: GFAP expression in the CST: Both CST regions (dorsal and ventral) exhibited stroke-induced increases in GFAP, an effect that was significantly reduced in stroke + CORT animals treated with CORT (dorsal CST; sham = 11.91% vs. stroke = 28.19%, p < 0.01; stroke vs. stroke + CORT = 3.367%, p < 0.001; ventral CST; sham = 17.54% vs. stroke = 44.24%, p < 0.01; stroke vs. stroke + CORT = 15.92%, p < 0.01).
