Brain 'pacemaker' increases memory by 15% in 25 patients
A brain implant, which sends electrical impulses like a pacemaker in heart, has been reported by UPenn neuroscientists to improve word recall by 15% in 25 epilepsy patients. The technology monitored neural activity in real-time using electrodes. It triggered a small electrical pulse when the patient seemed to forget the word, thereby improving performance in the memory-based task.
