- Tested in people
This was tested in people. That is the most reliable kind of research we share.
It used brain signals recorded from people, but it is not a treatment yet.
The short version
A new computer method read hand movements from tumor-affected brains more accurately.
What was studied. Researchers recorded brain signals from people with gliomas in the brain's movement area. The people made hand gestures while a computer learned to read the signals.
What they found. The new method, called PACT, used signals from healthy brains as a guide. It read the gestures more than 10% more accurately. The tumor-affected signals also came to look more like healthy brain signals.
What this means, and what it doesn't
What it could mean: Brain tumors can scramble the signals that devices use to read movement. This method may help such devices work better for people with a tumor. That could matter for future tools that turn thoughts into motion.
What it doesn't mean: This is not a treatment and it is not a cure. The authors call it a proof of concept. It was a test of computer methods on recorded brain signals. No one got a working device to use in daily life. Tools like this are still far from everyday care.
