Area of Science:

Neuroscience
Medical Imaging
Epileptology

Background:

Electroencephalography (EEG) is a long-standing tool for epilepsy characterization but lacks precise spatial localization of epileptiform activity.
Functional magnetic resonance imaging (fMRI) measures brain activity via blood oxygenation changes, offering high spatial resolution.

Purpose of the Study:

To explore the technical considerations and applications of simultaneous electroencephalography-functional magnetic resonance imaging (EEG-fMRI) for studying epilepsy.
To investigate the spatiotemporal mechanisms underlying epileptiform activity generation in the brain.

Main Methods:

Recording high-quality EEG simultaneously with fMRI to leverage the millisecond temporal resolution of EEG and millimeter spatial resolution of fMRI.
Discussing technical challenges and solutions for acquiring simultaneous EEG-fMRI data.

Main Results:

Simultaneous EEG-fMRI enables precise identification of the timing and location of interictal events.
This integrated neuroimaging technique enhances the investigation of brain activity patterns in epilepsy.

Conclusions:

Simultaneous EEG-fMRI represents a significant advancement for understanding epilepsy, offering improved spatiotemporal characterization of epileptiform activity.
The article reviews current applications, technical aspects, and future challenges for EEG-fMRI in human epilepsy research.
