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.

Seizure Onset Zone Identification From iEEG: A Review
Sign Up to like & getrecommendations! Published in 2022 at "IEEE Access"
DOI: 10.1109/access.2022.3182716
Abstract: This paper discusses the various methods of identifying the seizure onset zone (SOZ) from the intracranial electroencephalography (iEEG) data. Epilepsy, also known as seizure disorder, is a neurological condition caused due to disruption in the… read more here.

DOI: 10.1111/epi.16954
Abstract: Stereoelectroencephalography (SEEG) is being used more frequently in the pre‐surgical evaluation of children with focal epilepsy. It has been shown to be safe in children, but there are no multicenter studies assessing the rates and… read more here.

DOI: 10.1111/epi.17482
Abstract: Interictal spikes help localize seizure generators as part of surgical planning for drug‐resistant epilepsy. However, there are often multiple spike populations whose frequencies change over time, influenced by brain state. Understanding state changes in spike… read more here.

DOI: 10.1227/neu.0000000000002079
Abstract: BACKGROUND: Stereoelectroencephalography (sEEG) facilitates electrical sampling and evaluation of complex deep-seated, dispersed, and multifocal locations. Granger causality (GC), previously used to study seizure networks using interictal data from subdural grids, may help identify the seizure-onset… read more here.

DOI: 10.1371/journal.pcbi.1005953
Abstract: Epilepsy is one of the most common neurological disorders affecting about 1% of the world population. For patients with focal seizures that cannot be treated with antiepileptic drugs, the common treatment is a surgical procedure… read more here.

DOI: 10.3390/bioengineering9120769
Abstract: Successful surgery on drug-resistant epilepsy patients (DRE) needs precise localization of the seizure onset zone (SOZ). Previous studies analyzing this issue still face limitations, such as inadequate analysis of features, low sensitivity and limited generality.… read more here.

DOI: 10.3390/e22121415
Abstract: The design of a computer-aided system for identifying the seizure onset zone (SOZ) from interictal and ictal electroencephalograms (EEGs) is desired by epileptologists. This study aims to introduce the statistical features of high-frequency components (HFCs)… read more here.
