There are over 10 million people in the world with TBI (traumatic brain injury). These people have trouble remembering newly-formed memories. New works suggests a device implanted in the brain to help patients find their memories by using electric shocks. Trauma happens for many reasons. For example, several neurons can be damaged and the axons can separate from various neurons.
Researchers at the University of Pennsylvania have started tests on patients to try to find the memory control location. They are also zapping the brain of the patients in some areas of the brain, trying to figure out where to focus the device on.
