The Anatomo-Electrical Network Underlying Hypermotor Seizures

Frontiers in Neurology, 2018
PurposeHypermotor seizures (HMS) can be triggered by different epileptogenic foci and thus common symptomatic networks generating HMS may exist among these patients. The goal of the present study was to investigate the specialized networks underlying HMS

Invasive epilepsy surgery evaluation [PDF]

, 2016
Intracranial EEG (iEEG) recordings are widely used for the work up of pharmacoresistant epilepsy. Different iEEG recording techniques namely subdural grids, strips, depth electrodes and stereoencephalography (SEEG) are available with distinct limitations

On the Volume Conduction Model Validation with Stereo EEG Data [PDF]

, 2019
Volume conduction can be defined as the transmission of electric potential and magnetic field generated by a primary current source of brain activation in the surrounding medium, i.e., the human head.

Computer Modeling of Radiofrequency Thermocoagulation (RF-TC) Using the Recording Intracerebral Electrodes Implanted for Stereo Electroencephalography (SEEG) Monitoring

Our objective was to use computational modeling to provide a full and comprehensible physical description of the electrical and thermal behavior during electroencephalography-guided radiofrequency thermocoagulation (SEEG-RF-TC), a minimally invasive procedure to destroy epileptic foci in the brain.

The relationship between morphological lesion, magnetic source imaging, and intracranial stereo-electroencephalography in focal cortical dysplasia

NeuroImage: Clinical, 2017
Magnetoencephalography (MEG) is a useful non-invasive technique for presurgical evaluation of focal cortical dysplasia patients. We aimed at clarifying the precise spatial relationship between the spiking volume determined with MEG, the seizure onset ...

Vulnerability of the frontal-temporal connections in temporal lobe epilepsy. [PDF]

, 2008
ObjectiveIn temporal lobe epilepsy (TLE), frontal-temporal connections are integral parts of the epileptogenic network. Although frontal-temporal gray matter abnormalities have been consistently demonstrated in TLE, white matter connections between these

Variability of cortico‐cortical evoked potentials in the epileptogenic zone is related to seizure occurrence

Annals of Clinical and Translational Neurology
Introduction Cortico‐cortical evoked potentials (CCEPs) were described as reproducible during trains of single‐pulse electrical stimulations (SPES). Still, few studies described a variability of CCEPs that was higher within the epileptogenic zone (EZ ...

The Effect of Vascular Segmentation Methods on Stereotactic Trajectory Planning for Drug-Resistant Focal Epilepsy: A Retrospective Cohort Study [PDF]

, 2019
Background: Stereotactic neurosurgical procedures carry a risk of intracranial hemorrhage, which may result in significant morbidity and mortality. Vascular imaging is crucial for planning stereotactic procedures to prevent conflicts with intracranial ...

Refining computer-assisted SEEG planning with spatial priors – A novel comparison of implantation strategies across adult and paediatric centres [PDF]

Objectives: Computer-assisted planning (CAP) allows faster SEEG planning and improves grey matter sampling, orthogonal drilling angles to the skull, reduces risk scores and minimises intracerebral electrode length.
