About this study

The purpose of this study is to assess the thalamus area of the brain using stereotactic electroencephalography (an EEG with deep electrode placement inside the brain) to better understand its role in the starting and spreading of epileptic seizure activity.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
