SEEG Investigation of Mood Dysregulation in Epilepsy

Using the novel analysis of stereo-electroencephalography (SEEG) recordings, this proposal will investigate the activity and connectivity of mood regulation circuits in subjects with suspe...

Investigating the Neuronal Bases of Epilepsy With Micro-electrode Arrays in Candidates for Epilepsy Surgery

This study aims to uncover the neuronal bases of epilepsy by recording the activity of single neurons in the brain of patients with epilepsy who are candidates for assessment with intracra...

Atlas of Human Cognition by SEEG (MAPCOG-SEEG)

The main objective of MAPCOG_SEEG is to create a database including brain recordings of cognition performed in clinical routine in patients during the pre-surgical SEEG assessment. This ai...

Improvement of the Accuracy of Spatial Representation of Invasive Exploratory Electrodes in Focal Epilepsy

Reconstruction software allows visualization of cortical structure in 3 dimensions, showing on a single picture the position of all the electrodes. The EEG signal of each recording plot of...

Electrohaemodynamic Activity in Epileptic Children : Combined Video-EEG and Near-infrared Spectroscopy (NIRS) Analysis

This study is designed to evaluate the contribution of multimodal high-resolution EEG-NIRS electrical and local haemodynamic analysis (HR-EEG, HR-NIRS) to spatial localization of epileptog...

Surgical techniques: Stereoelectroencephalography-guided radiofrequency-thermocoagulation (SEEG-guided RF-TC).

Stereoelectroencephalography-guided radiofrequency-thermocoagulation (SEEG-guided RF-TC) consists of coupling SEEG investigation with RF-TC stereotactic lesioning directly through the recording electr...

Classification of microadenomas in patients with primary aldosteronism by steroid profiling.

In primary aldosteronism (PA) the differentiation of unilateral aldosterone-producing adenomas (APA) from bilateral adrenal hyperplasia (BAH) is usually performed by adrenal venous sampling (AVS) and/...

High-frequency oscillations and spikes running down after SEEG-guided thermocoagulations in the epileptogenic network of periventricular nodular heterotopia.

Epilepsy associated with periventricular nodular heterotopia (PNH) is characterized by complex relationships between the heterotopic and the normotopic cortex during the interictal state and at seizur...

Frameless robot-assisted stereoelectroencephalography for refractory epilepsy in pediatric patients: accuracy, usefulness, and technical issues.

Stereoelectroencephalography (SEEG) is an effective technique to help to locate and to delimit the epileptogenic area and/or to define relationships with functional cortical areas. We intend to descri...

Quantitative Signal Characteristics of Electrocorticography and Stereoelectroencephalography: The Effect of Contact Depth.

Patients undergoing epilepsy surgery often require invasive EEG, but few studies have examined the signal characteristics of contacts on the surface of the brain (electrocorticography, ECOG) versus de...

Medical and Biotech [MESH] Definitions

An autosomal dominant inherited partial epilepsy syndrome with onset between age 3 and 13 years. Seizures are characterized by PARESTHESIA and tonic or clonic activity of the lower face associated with drooling and dysarthria. In most cases, affected children are neurologically and developmentally normal. (From Epilepsia 1998 39;Suppl 4:S32-S41)

Electrodes which can be used to measure the concentration of particular ions in cells, tissues, or solutions.

Therapy for MOVEMENT DISORDERS, especially PARKINSON DISEASE, that applies electricity via stereotactic implantation of ELECTRODES in specific areas of the BRAIN such as the THALAMUS. The electrodes are attached to a neurostimulator placed subcutaneously.

Electric conductors through which an electric current enters or leaves a medium. When inserted, usually surgically, they are referred to as implanted electrodes.

A syndrome characterized by the onset of isolated language dysfunction in otherwise normal children (age of onset 4-7 years) and epileptiform discharges on ELECTROENCEPHALOGRAPHY. Seizures, including atypical absence (EPILEPSY, ABSENCE), complex partial (EPILEPSY, COMPLEX PARTIAL), and other types may occur. The electroencephalographic abnormalities and seizures tend to resolve by puberty. The language disorder may also resolve although some individuals are left with severe language dysfunction, including APHASIA and auditory AGNOSIA. (From Menkes, Textbook of Child Neurology, 5th ed, pp749-50; J Child Neurol 1997 Nov;12(8):489-495)
