^F3-a NR1-LI STT cells = (NR1-LI STT cells/total STT cells) × 100; phospho-NR1-LI STT cells = [phospho-NR1-LI STT cells/(NR1-LI STT cells + phospho-NR1-LI STT cells)] × 100. I, Ipsilateral to injection side; C, contralateral to injection side.

F3-150:  Significantly different from control (t test),p < 0.001.
