Summary:
Our brains lose the ability to link related memories as we age. Scientists genetically restored this brain function in middle-aged mice and identified an FDA-approved drug that achieves the same thing. The study suggests a new approach for combating middle-aged memory loss and a possible early intervention for dementia.

FULL STORY
Our brains rarely record single memories -- instead, they store memories into groups so that the recollection of one significant memory triggers the recall of others connected by time. As we age, however, our brains gradually lose this ability to link related memories.

Now UCLA researchers have discovered a key molecular mechanism behind memory linking. They've also identified a way to restore this brain function in middle-aged mice -- and an FDA-approved drug that achieves the same thing.

Published in Nature, the findings suggest a new method for strengthening human memory in middle age and a possible early intervention for dementia.

FR is good for triggering memories:)

so there is a gene that down regulates the ability of the brain to link memories.
why is it there?
