Pearson correlations (P ≤ 0.05 FDR-corrected) were performed to test the association between normalized current density maps in the EEG θ frequency band and WM performance (normalized inverse efficiency score [IES]), for social stimulus type. Analyses were run in all groups together and individually per group (HCs, bvFTD, AD and PD). Results are plotted in Fig. 2.A. These results were obtained with a demographically matched sample (see Table S3.1). AD: Alzheimer’s disease, BA: Brodmann area, bvFTD: behavioral-variant frontotemporal dementia, HCs: healthy controls, PD: Parkinson’s disease.
