- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This is a way to record data from surgery, not a treatment a patient can get.
The short version
Doctors found a reliable way to mark the brain spots they test during awake surgery.
What was studied. Doctors tried a new way to mark those brain spots on a scan taken before surgery. They tested it on Ninety spots in 19 patients having awake brain tumor surgery.
What they found. Two raters marked the spots on their own, and their marks lined up well. For 87% of the spots, the two marks were less than 2.5 mm apart. Tumor size, skull opening size, and a returning tumor did not change how well they agreed.
What this means, and what it doesn't
What it could mean: This is a research tool, not a treatment. It lets different teams record brain mapping: Finding out which parts of your brain do which jobs, like speech or movement. A scan before an operation can do it. It can also be done during one. Then small spots are tested with a tiny electric current. See the glossary data the same way. Over time that could build better maps of what each brain spot does.
What it doesn't mean: This does not mean a new treatment. It is not a cure, and it does not promise one. The study only tested a way to record and share data from surgery. It does not change the care a patient gets today. It is an early step, tried in one small group.
