- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was only tested in rabbits, not in people.
The short version
Scientists built a soft sensor that could warn surgeons when they press too hard on the brain.
What was studied. Researchers built a soft device that rests on the surface of the brain. They tested it during surgery in rabbits that had brain tumors removed.
What they found. The device tracked pressure, temperature, and brain signals during surgery. Pressure higher than 80 kPa caused brain injury that did not heal. Brain scans and a tissue stain confirmed that damage. The device also stuck to the brain gently and came off without hurting it.
What this means, and what it doesn't
What it could mean: Right now there is no direct way to measure how hard surgeons press on the brain. If this device works in people, it could give surgeons that number during surgery. That might help them avoid harming healthy brain tissue.
What it doesn't mean: This does not mean a new treatment is coming. The work was done in rabbits, not in people. No patient can get this device today. It does not treat or shrink a tumor, and it is not a cure. Much more testing in people would be needed first.
