Figure 1 Patient selection from 66 TLE patients who underwent invasive monitoring and surgery. Epilepsy Research 2014 108, 448-458DOI: (10.1016/j.eplepsyres.2013.12.008) Copyright © 2013 Elsevier B.V. Terms and Conditions

Figure 2 (A–C) Source distributions of G6, G11, and G20 whose source clusters were exclusively in the resection volume. (D–F) The source distributions of B5, B10, and B12 whose sources were clustered inside and outside the resection volume. The resection volume is marked with green. Each red sphere represents an interictal spike source located inside the resection volume, and each yellow sphere represents an interictal spike source outside the resection volume.

Figure 3 Source distribution of G3 (A), G8 (B), G12 (C), and G13 (D). When the electrodes did not fully cover the resection boundary, interictal spike sources tended to be dispersed.

Figure 4 Source distribution of B2 (A), B3 (B), and B8 (C). The interictal spike source clusters of 3 patients with unfavorable outcomes were found in a single lobe. However, the sources were not concentrated in the resection volume, but dispersed around the resection boundaries.
