Resting State Functional Connectivity in Perfusion Imaging: Correlation Maps with BOLD Connectivity and Resting State Perfusion
Figure 1
Maps of t values illustrating the connectivity between the seed in the left vACC and the cortical voxels in the left hemisphere.
In orange/yellow positive correlation levels; in blue, negative correlations. Maps were thresholded at both the uncorrected p = 0.005 level and shown in shaded color; full colors were used for effect significant at the more stringent peak-level p = 0.05 FWE-corrected threshold (t levels of 4.7–4.8). On the left, t maps were projected on an inflated rendering of the cortex for both the medial (top) and lateral (bottom) aspects of the left hemisphere. On the right, the same rendering on a flat rendering of the whole hemisphere. One can see that the superior third of flattened representation corresponds to the medial cortical surface, while the rest corresponds to the lateral surface. The main anatomical structures are indicated to illustrate reading of the flat rendering. Abbreviations: PCC: posterior cingulus; dACC: dorsal anterior cingulus (medial prefrontal cortex); vACC: ventral anterior cingulus (medial prefrontal cortex); PFC: prefrontal cortex; TPJ: temporo-parietal junction; ant, post: anterior, posterior.
