Figure 3 Resting state functional connections were calculated by conducting Pearson’s correlation analysis between the time series of every pair of measurement channels. A: Frontotemporal lobe dementia; B: Lewy body dementia; C: Parkinson’s disease dementia; D: Alzheimer’s disease. Red indicates higher activation, while blue indicates lower activation.
