Fig. 4. Temporal synchronization of fMRI and PET data.

Fig. 4.

fMRI time course data of the bolus injection cohort were binned to the temporal resolution of the PET data (1 min) and Pearson’s r correlation coefficient matrices were computed for the DMN-like structure. Resulting matrices were compared to (A) the original fMRI data and the (B) the [18F]FDG-PET data. Scatter plots of pair-wise correlations between brain regions (averaged across subjects) containing the DMN-like structure and linear fits were computed for (C) the comparison between original fMRI and binned fMRI data, as well as for (D) the comparison between binned fMRI and [18F]FDG-PET data. The correlation value represents Pearson’s correlation coefficient r. The different brain ROIs containing the DMN-like structure and their abbreviations are listed in Supplementary Table 2. (N = 15).
