Figure 2. Schematic polar plot and bar chart depicting distinct functional connectivity patterns of HIPc seeds with target ROIs distributed across the whole brain among CN and SCD subjects. The concentric circles depict parameter estimates representing the connectivity strength. Note that the functional connectivity data are extracted only from the brain regions which most robustly correlated with each HIPc seed in SCD and CN, corresponding to Supplementary Figure 3. AAL atlas with 116 regions was also used to define the ROIs in the polar plots. Abbreviations: CN, healthy controls; SCD, subjective cognitive decline; HIPc, hippocampal cognitive region; ROI, region of interest.
