Over the last five years, the U.S. Defense Advanced Research Projects Agency has been experimenting with devices intended to restore the memory-generation capacity of people with traumatic brain injuries.

This resulted in a device that monitors the brain’s electrical activity and provides a boost whenever signals are too weak to form memories.

Studies showed that memory retention improved as much as 37 percent in the patients who used the device.

The device was only tested on epileptic patients who already had electrodes implanted in their brains to monitor seizures.

As the device requires brain surgery in order to be used, it is unlikely that it will be on the consumer market any time soon
