Connectivity matrices of PLI values at different frequency bands.
From top to bottom:
Mean correlation across all subjects (N = 318).
Mean correlation across amyloid negative subjects (N = 255).
Mean correlation across amyloid positive subjects (N = 63).
The color bars show the correlation coefficients.
Lh-Frontal – PLI within left hemispheric frontal leads.
Rh-Frontal - PLI within right hemispheric frontal leads. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
