An electronic brain implant is being developed that has the potential to reverse memory loss.
The device is designed to replicate the function of the hippocampus, one of the first regions of the brain to be damaged by Alzheimer’s disease.
Using a small array of electrodes, it effectively “translates” neural memory signals into a form suitable for long-term storage.
So far the implant has only been tested on animals, but an early study of nine patients who already had electrodes implanted in their brains to control epilepsy indicated the system was likely to work with 90% accuracy.
