Interpretation of SEEG recordings

Neurophysiologie Clinique, 2018
The interpretation of SEEG recordings is a crucial step. It must be carried out by an epileptologist/neurophysiologist with sufficient training and qualification in this field. The objectives of the interpretation are to define the brain topography of interictal activities (irritative zone) and the epileptogenic zone, defined as the site of primary ...

Simultaneous SEEG-MEG-EEG recordings Overcome the SEEG limited spatial sampling

Epilepsy Research, 2016
During presurgical evaluation of pharmacoresistant partial epilepsies, stereoelectroencephalography (SEEG) records interictal and ictal activities directly but is inherently limited in spatial sampling. In contrast, scalp-EEG and MEG are less sensitive but provide a global view on brain activity.

Planning and management of SEEG

Neurophysiologie Clinique, 2018
Stereoelectroencephalography (SEEG) aims to define the epileptogenic zone (EZ), to study its relationship with functional areas and the causal lesion and to evaluate the possibility of surgical therapy. Planning of exploration is based on the validity of the hypotheses developed from electroclinical and imaging correlations.

A canonical visualization tool for SEEG electrodes

2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021
Stereoencephalographic (SEEG) electrodes are clinically implanted into the brains of patients with refractory epilepsy to locate foci of seizure onset. They are increasingly used in neurophysiology research to determine focal human brain activity in response to tasks or stimuli.

Thermocoagulation of the Ictal Onset Zone Using SEEG (Thermo-SEEG)

2018
Stereo-EEG (SEEG)-guided radiofrequency thermocoagulation (thermo-SEEG), is a stereotactic lesioning procedure in which the SEEG electrodes are used to deliver a radiofrequency current. This technique offers drug-resistant epileptic patients undergoing phase 2 investigations the possibility to benefit from lesions of the ictal onset zone without any ...

Basal temporal lobe epilepsy: SEEG electroclinical characteristics

Epilepsy Research, 2023
Temporal lobe epilepsy is the most common type of focal drug-resistant epilepsy. Seizures with predominant involvement of basal temporal regions (BTR) are not well characterized. In this stereo electroencephalography (SEEG) study, we aimed at describing the ictal networks involving BTR and the associated clinical features.We studied 24 patients ...

SEEG-guided thermocoagulations

Neurology, 2008
Intracranial stereotactic EEG recordings (SEEG) in presurgical epilepsy assessment are currently carried out in our department. The SEEG method generally used for exploration can also be used to perform radiofrequency thermocoagulations (RFTC) of the epileptic foci.

SEEG in Polymicrogyria: When and How?

2018
Polymicrogyria (PMG) is one of the most common malformations of cortical development (MCDs), with epilepsy affecting most patients. PMG-related drug-resistant epilepsy patients can be considered for surgery in well-selected cases. In this context, a comprehensive presurgical evaluation, often including stereo electroencephalography, is warranted to ...

La thermocoagulation multiple de foyers épileptogènes guidée par la SEEG (thermo-SEEG)

Neurochirurgie, 2008
In many patients with drug-resistant partial epilepsy, depth electrode recordings may be required to delineate the best region for cortical resection. We usually implant depth electrodes according to Talairach's stereoelectroencephalography (SEEG) methodology. Using these chronically-implanted depth electrodes, it is possible to generate radiofrequency

The Voyage of SEEG

Journal of Clinical Neurophysiology
Summary: It took 50 years for stereoelectroencephalography (SEEG) to cross the Atlantic. Conceived and designed before the advent of computers and modern technology, this method turned out to be perfectly suited to brain imaging and modern video and electrophysiological tools.
