DOI: 10.1016/j.clinph.2018.04.253
Abstract: Introduction Recently, we showed that three parameters of seizure onset were pertinent in the comparison of scalp and intracranial EEG: latency (La, pattern (Pa, pattern concordance between scalp and intracranial), and location (Lo) concordance. Discrepancy… read more here.

DOI: 10.1016/j.clinph.2021.06.013
Abstract: OBJECTIVE A major challenge that limits understanding and treatment of epileptic events from mesial temporal structures comes from our inability to detect and map interictal networks reproducibly using scalp electrodes. Here, we developed a novel… read more here.

DOI: 10.1016/j.neuroimage.2021.118133
Abstract: Accurate epileptogenic zone (EZ) or seizure onset zone (SOZ) localization is crucial for epilepsy surgery optimization. Previous animal and human studies on epilepsy have reported that changes in blood oxygen level-dependent (BOLD) signals induced by… read more here.

DOI: 10.1038/s41598-025-24994-6
Abstract: Accurate localization of the seizure onset zone (SoZ) is critical for effective surgical treatment in drug-resistant epilepsy. Traditional SoZ biomarkers, such as interictal epileptiform discharges (IEDs), high-frequency oscillation (HFO) rate, and relative band power (RBP),… read more here.

DOI: 10.1097/wnp.0000000000001106
Abstract: Supplemental Digital Content is Available in the Text. Purpose: Scalp-EEG incompletely covers the frontal lobe cortex. Underrepresentation of frontobasal or frontomesial structures, fast ictal spreading, and false lateralization impede scalp-EEG interpretation. Hence, we investigated the… read more here.

DOI: 10.1111/epi.15541
Abstract: Low‐voltage fast activity (LVF) and low‐frequency high‐amplitude periodic spiking (PS) are the two most common seizure‐onset patterns in mesiotemporal lobe epilepsy, with different underlying mechanisms, pathology, and postsurgical outcome. The present work aims to investigate… read more here.
