Network-specific Effects of Cortical Lesions on Average Cortical Volumetric Measures.
| Network | Pre-Correction Cortical Volume (ml) | Post-Correction Cortical Volume (ml) | % Change in Cortical Volume* |
|---|---|---|---|
| Default Mode (n = 44) | 67.4 +/− 25.8 | 70.6 +/− 26.2 | 5.3 +/− 6.1 |
| Salience (n = 33) | 30.8 +/− 12.6 | 31.5 +/− 12.4 | 3.8 +/− 4.7 |
| Limbic (n = 44) | 26.4 +/− 11.5 | 30.1 +/− 13.0 | 12.7 +/− 9.7 |
| Dorsal Attention (n = 16) | 31.7 +/− 12.1 | 31.9 +/− 12.0 | 2.2 +/− 3.0 |
| Executive Control (n = 36) | 39.5 +/− 15.8 | 40.8 +/− 16.0 | 4.5 +/− 5.5 |
| Somatomotor (n = 31) | 44.6 +/− 17.3 | 45.6 +/− 17.1 | 3.7 +/− 5.4 |
| Visual (n = 9) | 49.5 +/− 18.6 | 49.7 +/− 18.7 | 1.8 +/− 2.1 |
This table summarizes the percent volume change in each network caused by the lesion correction method. The average volume (ml) for each network of the 7-Network Yeo Atlas is provided for the 46 patients with cortical lesions. The limbic network was disproportionately lesioned compared to other networks due to the frontotemporal distribution of cortical lesions, as visualized in Fig. 4.
Measurements for the percent change in cortical volume include networks that have been impacted by the volume correction method. See column 2 of Table 4 for the number of paired (pre vs. post) volumes that were used to calculate each network's percent change in cortical volume.
