Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Non-Invasive Functional-Brain-Imaging with an OPM-based Magnetoencephalography System.

PLoS ONE, 2020
A non-invasive functional-brain-imaging system based on optically-pumped-magnetometers (OPM) is presented. The OPM-based magnetoencephalography (MEG) system features 20 OPM channels conforming to the subject's scalp. We have conducted two MEG experiments

Detection of interictal epileptiform discharges using multiple bilateral insertions of a newly developed microcatheter‐compatible endovascular electroencephalogram electrode: A clinical feasibility trial

Epilepsia Open, EarlyView.
Abstract Objective To assess the feasibility, technical performance, and safety of a novel endovascular electroencephalogram (eEEG) electrode, EP‐01, designed for minimally invasive seizure localization in patients with drug‐resistant epilepsy. Methods This single‐center, prospective, exploratory trial enrolled five patients with drug‐resistant ...

Utility of repeat stereotactic EEG in pediatric patients with tuberous sclerosis

Epilepsia Open, EarlyView.
Abstract Objective Tuberous sclerosis complex (TSC) is a rare genetic disorder associated with early‐onset drug‐resistant epilepsy (DRE) secondary to intracranial tubers. Many patients undergo stereo‐EEG (sEEG) for seizure onset localization, sometimes requiring multiple sEEGs and subsequent epilepsy surgeries. Our objective was to evaluate the effects

Functional Brain Mapping Using Magnetoencephalography [PDF]

, 2000
We present our early experiences of magnetoencephalography (MEG) especially on evaluating normal value. Various evoked fields including somatosensory, auditory and visual were measured in healthy adult volunteers with a NEUROMAG (ELEKTA, Sweden).
