High-Dimensional Directed Network Analysis of Focal Epileptic Seizure
The evolution of directed brain networks from preictal (300 seconds before seizure onset) to postictal phases (300 seconds after seizure onset)
Patient 1
The diamond at electrode G37 is the SOZ identified by expert interpretation of EEG data. Nodes in light blue are the regions that did not belong to any clusters. Nodes in the same other colors (either dark blue, green, pink, red, purple, orange or yellow) denote different identified clusters of regions. All nodes in red color belong to the SOZ cluster. Grey arrows indicate the identified directed connections between regions. Anterioinferior electrodes preceded by an “X” were resected in a previous epilepsy surgery.
