Effect of rAAV injections on apomorphine-induced rotation behavior. The groups are identified along the ordinate by which rAAV construct they received. The hatched barsrepresent the data obtained before intrastriatal vector injections (+SEM), and the solid bars represent the level of apomorphine-induced contralateral rotations 3 weeks after intrastriatal vector infections. There were no significant differences between the groups before or after rAAV injection (for statistics see Results). Each bar represents the mean of 12 observations.
