ure 7). Most conspicuous were homotopic connections between left and right central sulcus, primary somatosensory area, striate, and superior extra-striate cortex. Similarly, the connections that were most frequently weaker than ex- pected were dominated by those involving visual and somatomotor networks (see Figure 7C-D for more detail of the connections between visual and motor networks). Portions of the visual (VIS) and somatomotor (SMN) networks are situated near the midline dividing the left and right cerebral hemispheres. One possibil- ity is that these connections appear disproportionately often due to the short Euclidean distance between the brain regions that make up those networks (i.e. a bias towards shorter functional connections). While it is difficult to completely discount this possibility (and some of the most consistently strong/weak con- nections are short-range), many are long-range, especially those involving their homotopic partners (see Figure 8E), suggesting that whether or not a connec- tion participates in an excursion is not a mere consequence of its length. To verify that distance is not the principal driver of excursion counts, we calculated the Spearman rank-correlation of x − $_{ij}$, x + $_{ij}$, and x − $_{ij}$+ x + ij with Euclidean distance and found, r$_{−}$ = 0 . 14, r$_{+}$ = 0 . 035, and r$_{−}$$_{,}$$_{+}$ = − 0 . 092. Each of these correla- tions were significant at p < 0 . 005, due mainly to the fact that the correlations included many observations (113 × 112 / 2 points); the actual magnitudes of the correlations were small in all cases. We also wished to determine what was the influence, if any, of motion on this result. To this end, we divided our population of N = 80 participants into two groups based on the magnitude with which their excursion count time series was correlated with framewise displacement. The cutoff correlation for the “low motion correlation” group was | r$_{motion,excursioncount}$ | < 0 . 15. This resulted in a division of our participant pool into 38 low- and 42 high-motion correlation 19
