How the brain works during sleep and wakefulness in epilepsy

Researchers want to understand how your brain's activity and communication patterns change when you're awake versus asleep, especially in people with epilepsy that doesn't respond well to medication. They'll use a technique called stereoelectroencephalography (SEEG)—thin electrode wires already placed in your brain as part of your epilepsy evaluation—to record your brain activity. They'll also gently stimulate small areas of your brain with tiny electrical pulses to map how different brain regions communicate with each other.

Sleep profoundly affects how excitable your brain is and how different brain regions talk to each other. By studying these changes in people with difficult-to-treat epilepsy, researchers hope to better understand what goes wrong in epilepsy and potentially improve how doctors predict which brain areas need to be treated.
