In order to find new and better ways to treat neurological diseases, scientists have created a wireless ‘pacemaker for the brain’ that monitors brain’s activity and stimulates electric currents simultaneously.

Researchers at University of California, Berkeley, have created a device called WAND that works like a ‘pacemaker for the brain’, as they call it. The device works similar to a heart pacemaker, monitoring brain’s electrical activity and stimulating electric current in brain simultaneously if it detects something wrong. It thus provides a better treatment for neurological diseases like Parkinson’s and epilepsy.
