Regional interaction and correlation between hypometabolism and microglia activation. a Microglia activation and hypometabolism interaction (in red) overimposed on the surface-based map. b Correlation analysis obtained extracting cerebral glucose metabolism value and [11C]-PK 11195 binding potentials from the interaction regions (red line shows linear fitting). Correlation analysis indicates positive correlation between the two measures, meaning that higher microglia activation correlates with higher level of regional hypometabolism in the same regions
