Impaired connectivity between anxiety-related regions in multiple sclerosis patients. A In a second patient cohort (n = 18) TMS–HD-EEG was performed at rest and effective connectivity between the PFC, amygdala and hippocampus was measured and compared to healthy controls (n = 18). B Theta and gamma frequency bands revealed no connectivity between PFC and amygdala in patients versus controls
