The US military wants to treat shell-shocked soldiers with memory loss

Two teams are testing electrical stimulation in epilepsy patients

Brain implants could also help people who have lost memory after strokes

One day, such implants may even be used to 'share memories' with others

From the Vulcan mind meld to Professor Dumbledore's Pensieve, there are countless ways in which people share memories in fictional films and TV shows.

But such fantastical ideas could soon become a reality, using electrodes implanted in the brain.

Neuroscientists have already begun trialling implants that boost memory loss, and in the future they believe these implants could be used to replicate memories in the brains of others.
