(A) Timelines of the experiment. (B) Comparisons of contralateral forelimb akinesia in the experimental (NpHR) and control (PBS) groups, as assessed by the percentage of adjusted step numbers of the contralateral forelimb to the ipsilateral forelimb. The leftmost bars represent the baseline values before the onset of parkinsonian symptoms; the middle and rightmost bars represent 35 days after A53T-SNCA injection, pre-illumination and post-illumination, respectively.
