In a proposed device, two of the new chips would be embedded in a chassis located outside the head. Each chip could monitor electrical activity from 64 electrodes located into the brain while simultaneously delivering electrical stimulation to prevent unwanted seizures or tremors. Credit

Device fine-tunes treatment by stimulating and and recording electric current in the brain at the same time. A new neurostimulator developed by engineers at the University of California, Berkeley, can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and Parkinson’s.
The device, named the WAND, works like a “pacemaker for the brain,” monitoring the brain’s ele...
