Eigenvector Centrality Mapping for Analyzing Connectivity Patterns in fMRI Data of the Human Brain

Figure 9

Pairwise t-test between sated and hungry subjects using spectral coherence in experiment 2.

The results are shown for three frequencies (0.1 Hz, 0.05 Hz, 0.033 Hz) thresholded at p 0.05 (corrected). Voxels where centrality values were significantly larger in the sated state are shown in red, the reverse is shown in blue. Note that the difference in precuneus is only present at frequencies 0.1 Hz. At 0.033 Hz a significant difference becomes apparent at the ventral striatum. Talairach coordinates of slice positions are (−8,−60,−2), see Table 1.
