The Future of Intracranial EEG Recording in Epilepsy: a Technological Issue?
نویسندگان
چکیده
Intracranial EEG information used for epilepsy surgery has been provided from large widely spaced electrodes over a narrow bandwidth. However, over the last decades, research on animal and more recently on human, promoted by increased interest in developing high-density microelectrode arrays (MEA), has opened new windows for the comprehension of seizure origin and propagation at a submillimeter scale. From an electrophysiological perspective MEA demonstrate to be able to record local field potentials recordings and possibly single units in the mouse cortex. The limitations on the number of channels that can be recorded simultaneously may limit the number of microelectrodes that can be considered and consequently the extent of brain coverage. Thanks to improving microfabrication techniques, several prototypes of MEA are under development and investigation. They will certainly play an important role in the improvement of the understanding of the complicated and evolving concept of epileptogenesis and provide the development of new strategies regarding neurosurgical therapeutic issues. .

طبقه بندی حمله صرعی در سیگنال EEG با استفاده از سیستم استنتاج عصبی- فازی تطابقی
Background & Aims: Epilepsy is a brain disorder in which nerve cells receive abnormal inputs. This disease can lead to abnormal behaviors, feelings and symptoms such as loss of consciousness, which is called the seizure. Identification and classification of the epileptic seizure events in electroencephalographic signal against free seizure intervals plays an important role in clinical investiga...
متن کاملLocalization of epileptogenic zone in temporal lobe epilepsy by ictal scalp EEG
Our aim was to evaluate the ability to localize the epileptogenic zone in temporal lobe epilepsy (TLE) by ictal scalp electroencephalogram (EEG). Using simultaneous video recording, we analysed scalp EEG activity during ictal periods in 38 patients (30 patients with medial TLE (MTLE) and eight with lateral TLE (LTLE)). In 14 patients, intracranial ictal EEGs were recorded with depth electrodes,...
متن کاملElectroencephalography in Mesial Temporal Lobe Epilepsy: A Review
Electroencephalography (EEG) has an important role in the diagnosis and classification of epilepsy. It can provide information for predicting the response to antiseizure drugs and to identify the surgically remediable epilepsies. In temporal lobe epilepsy (TLE) seizures could originate in the medial or lateral neocortical temporal region, and many of these patients are refractory to medical tre...
متن کاملThree-dimensional intracranial EEG monitoring in presurgical assessment of MRI-negative frontal lobe epilepsy
Magnetic resonance imaging (MRI)-negative epilepsy is associated with poor clinical outcomes prognosis. The present study was aimed to assess whether intracranial 3D interictal and ictal electroencephalography (EEG) findings, a combination of EEG at a different depth, in addition to clinical, scalp EEG, and positron emission tomography-computed tomography (PETCT) data help to predict outcome in...
متن کاملUtility of Independent Component Analysis for Interpretation of Intracranial EEG
Electrode arrays are sometimes implanted in the brains of patients with intractable epilepsy to better localize seizure foci before epilepsy surgery. Analysis of intracranial EEG (iEEG) recordings is typically performed in the electrode channel domain without explicit separation of the sources that generate the signals. However, intracranial EEG signals, like scalp EEG signals, could be linear ...
