To minimize functional morbidity associated with brain surgery, new preventive approaches (also referred to as "prehabilitation") by using motor-imagery-based computer interfaces (MI-BCIs) can be utilized. To achieve successful MI-BCI performance for prehabilitation purposes, the characteristics of an electrocorticographic (ECoG) signal that is associated with overt motor function ("real...
determining the epileptogenic zone (EZ) from intracranial electroencephalography (iEEG) recordings is an important but nontrivial task. In this pilot study we demonstrate the usefulness of phasesynchronized phase-amplitude coupling constellations as a hybrid construct from well-established phase-amplitude and phase-phase coupling measurements. Also, we introduce a heuristic measure related to spectral...
The study was aimed at evaluating the changes in dynamical connectivity, between interictal, preictal and ictal condition, among signals derived from StereoEEG recordings in patients with Taylor's type focal cortical dysplasia (FCD type-II), by means of Partial Directed Coherence and indexes derived from graph theory. Results showed that seizures are characterized by an increased synchronization,...
