Investigating brain function in epilepsy patients using implanted electrodes
Human Intracranial Electrophysiology
NA · Dartmouth-Hitchcock Medical Center · NCT05529264
This study is testing how well different parts of the brain work in people with epilepsy who are getting ready for surgery, by using implanted electrodes to record brain activity while they do memory and attention tasks.

What this trial studies
This study enrolls patients with epilepsy who are undergoing evaluation for surgery and have electrodes implanted in their brains or on their scalps. Participants will engage in daily sessions that test various cognitive functions such as memory, language, and attention while their brain activity is recorded using Human Intracranial Electrophysiology (HIE). The study aims to understand the localization and function of the human brain by analyzing brain signals during specific tasks, alongside other physiological data. This research builds on previous studies conducted at Dartmouth-Hitchcock Medical Center.
Who should consider this trial
Good fit: Ideal candidates include adults aged 18 and older with a diagnosis of refractory epilepsy undergoing intracranial EEG recording.
Not a fit: Patients with additional neurological or psychiatric conditions that may interfere with the study are unlikely to benefit.
Why it matters
Potential benefit: If successful, this study could enhance our understanding of brain function and improve treatment strategies for epilepsy.
How similar studies have performed: Previous studies using similar electrophysiological methods have shown promise in understanding brain function, indicating potential for success in this approach.
