WebA total of 20 patients PwPD and 15 HC participated in the fMRI study. We analyzed their performance of a Test of sentence comprehension (ToSC) adjusted for fMRI. A task-dependent functional connectivity analysis of the striatum was conducted using the psychophysiological interaction method (PPI). WebEEG/fMRI studies of GGEs utilizing standard fMRI data analysis methods typically show symmetric changes in thalamic and cortical blood-oxygen-level-dependent (BOLD) signal related to GSWDs ( Fig. 1) [23–32]. Observed cortical changes usually include both GSWD-related activation and deactivation in multiple regions.
