Correlation matrix between clinical features and cortical structures. Upper: Clustering of cerebral cortical areas. Lower right: Clustering of clinical symptoms. Lower left: Correlation between structures and symptoms (green, negative correlation; red, positive correlation), which shows components of seizure semiology related to different early spread networks in varying degrees. *P < 0.05
