Scientists from the group of Dr. Tonio Ball at the Cluster of Excellence "BrainLinks-BrainTools" and the Bernstein Center Freiburg have developed a new system, which allows doctors to map brain surface activity with minimal patient cooperation.
The researchers implanted electrocorticography electrodes on the brain of the patients and filmed them while they were performing everyday movements. Concurrently, their brain activity was recorded and synchronized with the video.
AdvertisementLater, the researchers correlated brain activity to specific movements and actions and then compared it with traditional mapping methods. Results indicated that such an approach would be effective in mapping brain surface activity.
This could help patients with drug-resistant epilepsy in whom surgical ablation is the best treatment to alleviate their seizures.
