Identifying the Seizure Onset Zone using Intracranial EEG-fMRI
… an effective technique for identification of the seizure onset zone (SOZ) in patients with refractory epilepsy. Recent studies have shown that using intracranial electrodes (iEEG) combined with fMRI offers unique insight into changes in blood oxygen-level dependent (BOLD) responses associated with …

The negative BOLD response as a marker of the seizure onset zone
… people worldwide. For most individuals, these seizures can be controlled using medications, however nearly 1 in 3 people may need surgery to achieve seizure freedom. For this surgery to be successful, the brain region generating the seizures, which contains the critical seizure onset zone …

UNSUPERVISED CLASSIFICATION OF HIGH-FREQUENCY OSCILLATIONS IN NEOCORTICAL EPILEPSY AND CONTROL PATIENTS
… the brain areas responsible for generating their seizures can be localized. High-frequency (100-500 Hz) field-potential oscillations (HFOs) are emerging as a candidate biomarker for epileptogenic networks, but quantitative HFO studies are hampered by selection bias arising out of the need to …

The Interictal State In Epilepsy And Behavior
… to cure it. Patients with epilepsy have both seizures as well as another type of abnormal activity between seizures, known as interictal spikes. Interictal spikes have thus far been poorly researched, yet growing evidence supports an important role for them in epilepsy. In this project, we …

Computational Approaches To Epilepsy: Graph Networks For Localization And Multi-Model Approach For Prediction
… characterized by a lack of response to antiseizure medications. For these individuals, the primary remaining treatments are surgical intervention or neuromodulation. The success of these interventions depends mainly on solving two critical challenges: first, precisely localizing the seizure …

Investigation of High Frequency Oscillations in Epilepsy Using Computational Intelligence
… critically on the accurate delineation of the seizure onset zone (SOZ). High frequency oscillations (HFOs, 80 - 500 Hz) are proposed as putative biomarkers in epilepsy with their potentials of identifying the SOZ, either by augmenting or replacing the current preoperative evaluation modality …
