Safety of Simultaneous Scalp and Intracranial EEG and fMRI: Evaluation of RF-Induced Heating [PDF]
BioengineeringThe acquisition of electroencephalography (EEG) concurrently with functional magnetic resonance imaging (fMRI) requires a careful consideration of the health hazards resulting from interactions between the scanner’s electromagnetic fields and EEG ...

Intracranial EEG Substrates of Scalp EEG Interictal Spikes [PDF]
Epilepsia, 2005 Summary: Purpose: To determine the area of cortical generators of scalp EEG interictal spikes, such as those in the temporal lobe epilepsy. Methods: We recorded simultaneously 26 channels of scalp EEG with subtemporal supplementary electrodes and 46 to 98 channels of intracranial EEG in 16 surgery candidates with temporal lobe epilepsy.

Intracranial EEG in the 21st Century [PDF]
Epilepsy Currents, 2020 Intracranial electroencephalography (iEEG) has been the mainstay of identifying the seizure onset zone (SOZ), a key diagnostic procedure in addition to neuroimaging when considering epilepsy surgery. In many patients, iEEG has been the basis for resective epilepsy surgery, to date still the most successful treatment for drug-resistant epilepsy ...

Intracranial EEG Seizure-Onset Patterns
Pediatric Neurology Briefs, 2014 Investigators at Montreal Neurological Institute and Hospital, Canada, studied intracranial electroencephalographic seizure-onset patterns associated with different epileptogenic lesions, and defined high-frequency oscillation correlates of each pattern.

Long-Term Ambulatory Intracranial EEG. [PDF]
Stereotact Funct NeurosurgBackground: Long-term ambulatory intracranial EEG is beginning to transform epilepsy care by revealing new insights into seizure patterns and treatment responses over the course of months to years. The feasibility of such monitoring was initially demonstrated through a dedicated recording system.

Neurobiology of Disease, 2022 Objectives: Malformations of cortical development (MCDs) are common causes of drug-resistant epilepsy. The mechanisms underlying the associated epileptogenesis and ictogenesis remain poorly elucidated. EEG can help in understanding these mechanisms.

Zero-crossing patterns reveal subtle epileptiform discharges in the scalp EEG
Scientific Reports, 2021 Clinical diagnosis of epilepsy depends heavily on the detection of interictal epileptiform discharges (IEDs) from scalp electroencephalographic (EEG) signals, which by purely visual means is far from straightforward.

Imaging of focal seizures with Electrical Impedance Tomography and depth electrodes in real time
NeuroImage, 2021 Intracranial EEG is the current gold standard technique for localizing seizures for surgery, but it can be insensitive to tangential dipole or distant sources.

Heliyon, 2023 Background: Several cases of temporal lobe epilepsy (TLE) showing false lateralization of ictal scalp electroencephalography (EEG) have been reported. However, TLE with cavernous malformation indicating false lateralization of both ictal scalp EEG and ...
