Combining virtual reality and non-invasive deep-brain electrical stimulation, researchers have improved healthy individuals’ spatial memory – the kind that helps you remember where you left the car keys. The approach has great potential for treating cognitive decline due to disease or injury without drugs or surgery.

EPFL researchers have combined virtual reality, non-invasive brain stimulation and advanced brain imaging techniques to improve spatial navigation in healthy participants. The study is a first step in addressing dementia in an aging population without medication or surgery.
