Fig 1: NeuN staining in the bilateral V1 region after unilateral ONC. (A) NeuN expression in the NC 3 days after ONC, 1 week after ONC, 2 weeks after ONC, and 4 weeks after ONC at the bilateral V1 region as shown by IHC. (B) The counts of NeuN stained cells and densitometric analysis of IHC. Scale bar: 50 µm. Summary data are presented as mean ± SEM. *P < 0.05, **P < 0.001, ***P < 0.0001 compared with NC group (n = 5 animals per group).
