Fig. 2From: Reduced task-related functional connectivity during a set-shifting task in unmedicated early-stage Parkinson’s disease patientsNegative coupling of DLPFC and superior frontal gyrus. T-statistic images of negative connectivity in the [successful shift > successful repeat] contrast, corrected for mean RT on shift trials. A voxel-level threshold of p < .001 is used with an extent threshold of 10 voxelsBack to article page
