Fig. 2

Association of brain metabolism and cognitive tests. Abbreviations: dACC = dorsal anterior cingulate cortex. dlPFC = dorsolateral prefrontal cortex. Ekman test = Ekman 60 faces test. SRI = Stereotypy Rating Inventory. Scatterplots display A Association of brain metabolism in the dACC and Ekman 60 faces test (facial emotion recognition). Lower scores on the Ekman 60 faces test denote worse facial emotion recognition B Association of brain metabolism in the inferior temporal gyrus and Ekman 60 faces test (facial emotion recognition) C Association of brain metabolism in dlPFC and compulsive behaviour. Higher scores on the SRI denote more and severe compulsive behaviour. Curved lines represent mean confidence intervals. Right side of the figure: corresponding visual representation of patterns of metabolism of FTD and PPD patients that associate with facial emotion recognition and compulsive behaviour. All voxels are scaled to the mean uptake using proportional scaling, thus negative values reflect lower mean values relative to the global uptake. Surface rendering of significant voxels from contrasts of FTD and PPD patients are displayed at p < 0.001, all significant clusters are displayed in Table 3. Images were created with SPM12
