Effects of picrotoxin (0.165 nmol/μl) injection into the globus pallidus in the reaction-time task for sham (n = 6) and 6-OHDA-lesioned rats (n = 6). Performance is expressed by the mean number of correct and delayed trials ± SEM and by the mean ± SEM reaction times in milliseconds. Performance is measured on one preoperative session (Pre), one postoperative session (Post) corresponding to the day before picrotoxin injection (day 26). *Significantly different from preoperative performance (p < 0.05, Fisher's PLSD test after significant ANOVA). ^#Significantly different from postoperative performance (p < 0.05, Fisher's PLSD test after significant ANOVA).
