Background: Cognitive deficits in Parkinson's disease (PD) patients are well described, however, their underlying neural mechanisms as assessed by electrophysiology are not clear.
Objectives: To reveal specific neural network alterations during the performance of cognitive tasks in PD patients using electroencephalography (EEG).
Methods: Ninety participants, 60 PD patients and 30 controls underwent EEG recording while performing a GO/NOGO task.
