This was tested in people. That is the most reliable kind of research we share.
This is one case seen in a person, and the benefit is not proven yet.
The short version
During one woman's brain surgery, a monitor showed her brain activity drop all at once.
What was studied. Doctors wrote up one patient. A 28-year-old woman had surgery to drain fluid buildup in her brain, caused by a tumor. Her brain waves were watched during the surgery with a simple two-channel monitor.
What they found. Twice during the surgery, her heart raced and her blood pressure shot up. Each time, brain activity fell sharply on both sides of her brain. Her heart and blood pressure settled within 15 min, her brain waves took 55 min, and she was close to normal within 4 h.
What this means, and what it doesn't
What it could mean: Watching brain waves during this surgery might give an early warning sign. But the doctors who wrote this up say the extra value is not proven. A sudden surge in heart rate and blood pressure already tells the team to stop and pull back.
What it doesn't mean: This is one patient, written up as a single case. The authors say it is only the second case like it ever published. It does not show that brain wave monitors help patients do better. It is not a new treatment, and it is not a cure. It does not change the care you would get today.
