What is EEG-fMRI?
EEG-fMRI is a technique that combines electroencephalography and functional magnetic resonance imaging to study brain activity.
How does this protocol help epilepsy patients?
It helps in localizing seizure onset and guiding neurosurgical treatment for patients who do not respond to medication.
What are the key steps in setting up EEG-fMRI?
Key steps include marking electrode positions, applying conductive paste, and connecting EEG equipment to the MRI scanner.
Why is artifact removal important?
Artifact removal is crucial for ensuring the accuracy and reliability of EEG data during analysis.
Can this protocol be used in research?
Yes, the protocol is designed for both clinical and research settings.
What is the significance of the 10-20 system?
The 10-20 system is a standardized method for placing EEG electrodes on the scalp to ensure consistency in recordings.
