Read our Epilepsy research guide →Researchers are trying to better understand how epilepsy disrupts the way different parts of the brain communicate with each other. This study uses three types of brain recordings — surface recordings (EEG and MEG) and deeper electrode recordings (SEEG) — to map these brain networks at different levels of detail. The goal is to figure out which measurement methods best capture how the brain is working during epilepsy.
Current methods for detecting brain network problems in epilepsy have limitations, especially when using only non-invasive surface recordings. This study wants to find out which brain measurement techniques are most useful in practice, and whether information doctors see from deeper recordings can also be detected from safer, non-invasive surface recordings alone.

For patients: You will undergo brain recordings during your already-planned electrode implantation period. Researchers will simultaneously record your brain activity using three methods — two non-invasive surface recordings (EEG and MEG) and one deeper recording (SEEG) that your doctor is already placing for clinical reasons. For healthy volunteers: You will come for one brain imaging visit where researchers will record your brain activity using the two non-invasive surface methods only (EEG and MEG), with no additional risk or discomfort.
