Number of the seizures and of the connections before and after ctDCS. Functional connectivity changes are shown in the whole band and in the specific frequency bands (theta, alpha, and beta). PT, patient; TOTAL, among all regions; epileptic focus, one of the two nodes of the changed connection is the epileptic macro-region; epileptic focus (%), percentage with respect to the TOTAL changed connections; DRE, drug-resistant epileptic patient.
