How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
No phase is listed for this study, so it is still research and not care your own doctor can give you.
Status: Enrolling by invitation. It is only taking people the trial team invites. You cannot sign up for this one directly.

The short version
This study looks at how a common brain mapping tool affects the brain during surgery.
Who this trial is for. This study is for people who are having brain surgery to treat epilepsy or to remove a brain tumor. It studies a tool called electrocortical stimulation, or ECS, which surgeons use during surgery to find the parts of the brain that handle movement and speech.
Where it stands. This trial has not reported results. The team is measuring how ECS affects brain cells at the spot being stimulated. They are also measuring how it affects the brain areas used for speech and language. In some people, the surface of the brain will also be cooled a little. The source says this is painless and does not harm how the brain works. The answers are not in yet.
What this means, and what it doesn't
What it could mean: ECS has been used for decades, but how it works is still not well understood. The people running this study hope that better understanding could lead to shorter surgeries and better care in the future. People in the study do simple tasks like reading words or naming pictures. That is much like the testing already done during a hospital stay. If you are facing brain surgery for a tumor or for epilepsy, you could ask your care team about this study.
What it doesn't mean: This does not mean ECS mapping is being improved for you right now. A trial is a test, not a proven treatment. Joining a study is not a guarantee that it will help you. It is not a promise of a cure. Whether anyone can take part is decided by the trial team, not by us.
