Rules of memory rewritten in study described as "beautiful, elegant and extremely impressive"

the human brain

What really happens when we make and store memories has been unravelled in a discovery that surprised even the scientists who made it.

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.

The genetic variants for happiness are mainly expressed in the central nervous system and the adrenal glands and pancreatic system.
