Brain-Computer interface aims to stop epileptic seizures before they start

This early study at Mayo Clinic tests a new implantable device called the Brain Interchange System in up to 8 people with drug-resistant epilepsy. The device records high-speed brain signals and can deliver targeted electrical stimulation to prevent seizures. Unlike current systems that react after a seizure starts, this one aims to detect warning signals and stop seizures before they happen. For now, the study only checks if the device works as intended, not whether it actually controls seizures.
