The average numbers of PKH26 (+) (a) and YFP (+) (b) neurons within depths of 0–160 µm at every 20 µm. The average numbers of both neurons were compared among MOS (n = 4), SB + MOS (n = 4), and vehicle-treated (n = 4) groups. Black bar MOS; gray bar SB + MOS; white bar vehicle. *P < 0.05 MOS versus SB + MOS. **P < 0.005 MOS versus SB + MOS. ^# P < 0.05 MOS versus vehicle. ^## P < 0.005 MOS versus vehicle
