Figure 2. NeuN immunostaining of sections of the SC. A: Representative microphotographs of the superior colliculus (SC) are shown for the control group (untreated) for 180 days after N-methyl-D-aspartate (NMDA) injection (the contralateral side and the ipsilateral side). The scale bars represent 30 µm. B: The average number of neuronal nuclear specific protein (NeuN)-labeled neurons was counted in the SC. Each value represents the mean±SEM (n=4–11). The asterisk indicates p<0.05, while the double asterisk represents p<0.01 versus control (untreated mice; Dunnett’s test).
