Background Continuous electroencephalography (CEEG) monitoring is used for detection of convulsive and nonconvulsive seizures and assessing the degree of encephalopathy in critically ill patients. A commonly seen encephalopathic pattern on CEEG is generalized periodic discharges with triphasic wave (TW) morphology. The underlying role and prognostic significance of TW in relationship to intracr...

Surgical treatment of epilepsy is a challenge for patients with non-contributive brain magnetic resonance imaging. However, surgery is feasible if the seizure-onset zone is precisely delineated through intracranial electroencephalography recording. We recently described a method, volumetric imaging of epileptic spikes, to delineate the spiking volume of patients with focal epilepsy using magnet...

Temporal lobe seizures have a significant chance to induce impairment of normal brain functions. Even after the termination of ictal discharges, during the post-ictal period, loss of consciousness, decreased responsiveness or other cognitive dysfunctions can persist. Previous studies have found various anatomical and functional abnormalities accompanying temporal lobe seizures, including an abn...

Intracranial electroencephalography (iEEG) is a neuroscience technique in which electrical recordings are made from electrodes making direct contact with the human brain. While patients with intractable epilepsy are being recorded with pre-operative iEEG, they can opt to participate in cognitive research tasks, thus giving cognitive neuroscientists access to unique and spatiotemporally rich dat...

The value and reliability of the combined results of skull radiographs, electroencephalography, echoencephalography, isotope angiography, and brain scanning in 147 patients suspected of having an intracranial space occupying lesions are analysed. The overall accuracy of the technique was 79%. No false negatives were found. The advantages of adopting the system proposed by the authors in everyda...
