Summary

The purpose of the study is to use a new method of high-density electroencephalogram (HD-EEG) recording to map brain areas important for movement, sensation, language, emotion, and cognition.

DIAGNOSTIC_TEST

High-density electroencephalogram (HD-EEG)

This study will focus on obtaining a special type of high-density scalp electroencephalography (HD-EEG) recordings in patients with neurological disorders (i.e., epilepsy, brain tumor, stroke, etc.) and appropriately matched controls. HD-EEG is a scalp EEG which uses up to 256 channels compared to the standard 21 channels used for routine clinical applications. The reason for using more channels to record is for more precise localization of epileptogenic foci and/or more precise mapping of brain functions. This type of EEG requires the use of patient's own MRI scan to precisely localize activity. Therefore, all patients and controls getting an HD-EEG will require a structural MRI scan.
