- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Signals were measured in people during surgery, but this is not a treatment or a test you can get.
The short version
Brain signals recorded during surgery looked different depending on the type of tumor.
What was studied. Doctors recorded electrical signals from the brain surface during surgery in 100 people. Some were having tumor surgery. Others were having surgery for epilepsy or for deep brain stimulation.
What they found. Averages taken across the whole brain did not tell the tumor types apart. But signals measured spot by spot changed with how close the tumor was and how much tumor sat nearby. These patterns differed by tumor type, and signals also looked off in brain tissue that looked normal on scans.
What this means, and what it doesn't
What it could mean: Brain signals might one day help show how far tumor cells reach. That could add to what scans already show. Right now it is a research idea, not part of care.
What it doesn't mean: This is not a treatment, and no one was treated based on these signals. The recordings were taken during surgery people were already having. This is early research in a small group, far from everyday care. It is not a promise of a cure.
