Morphological changes in astrocytes were detected in the dentate gyrus. a Morphological analysis of type II and type III astrocytes by sholl analysis. (Immunofluorescence for GFAP, gradation from red to blue; depth of Z-projection is 0-30 μm, Concentric circles are spaced at 10 μm). b Number of intersections between each circle and processes of type II astrocytes in dentate gyrus from control, 1 h and 24 h groups (Control, N = 9, n = 34; 1 h, N = 10, n = 40; 24 h, N = 8, n = 56). c Number of intersections between each circle and processes of type III astrocyte in the dentate gyrus from control, 1 h and 24 h group (Control, N = 10, n = 111; 1 h, N = 12, n = 155; 24 h, N = 10, n = 117). *p < 0.05, ***p < 0.001. GFAP, glial fibrillary acidic protein
