Figure 3. GFAP-positive astrocyte of sections of the SC. A: Representative microphotographs of the superior colliculus (SC; the contralateral side and the ipsilateral side) are shown for the control group (untreated) 3, 7, 30, 90, and 180 days after N-methyl-D-aspartate (NMDA) injection. The scale bar represents 30 µm. B: The average number of glial fibrillary acid protein (GFAP)-positive astrocytes was counted in the SC. Each value represents the mean±SEM (n=3). The asterisk indicates p<0.05, while the double asterisk represents p<0.01 versus control (untreated mice; Dunnett’s test).
