Human memory

The US and Japanese team found that the brain "doubles up" by simultaneously making two memories of events.

One is for the here-and-now and the other for a lifetime, they found.

It had been thought that all memories start as a short-term memory and are then slowly converted into a long-term one.

Experts said the findings were surprising, but also beautiful and convincing.

'Significant advance'

Two parts of the brain are heavily involved in remembering our personal experiences.

The device, called neuroprosthetic, is mainly aimed at people suffering from Alzheimer’s or some kind of brain trauma.

Before telling you more about the device, let me tell you something about Kernel, which was started earlier this year with an aim to build the world’s first neural prosthetic for human intelligence enhancement. The money behind the company comes from tech entrepreneur Bryan Johnson who sold his payments company to PayPal for $800 million and started a venture fund.
