“The deep brain stimulation implant, developed by researchers at Stanford University, aims to boost activity between the regions responsible for consciousness learning, memory, thinking and problem solving.

During early trials, five people with brain injuries reported they were able to concentrate, read, remember, drive properly and get through the day without napping.

The therapy proved so effective that researchers had trouble completing the final phase of the study, which was to switch off the device for three random participants – after two of the patients declined.”
