a) Mean reaction times (RT) to go arrows On and Off DAAg medications for PD groups (PD-C and PD-ICD). Mean reaction times were similar between groups and across medication states. Error bars reflect the standard error of the mean. b) Stop signal reaction times (SSRT) On and Off DAAg medications for PD groups (PD-C and PD-ICD). Mean SSRTs were comparable when patients were On or Off DAAg, however, the PD-ICD group showed faster SSRTs when compared to the PD-C group, independent of medication state. Error bars reflect the standard error of the mean.
