科学家或已知道抹除记忆的方法

 

Or what if you could alter unpleasant memories so they're no longer upsetting? Or create entirely² new memories of events that never occurred? 

 

It sounds like the stuff of science fiction, but according to a new documentary that premiered in the US recently, scientists have discovered how to do just that - and more. 

 

"Memory Hackers," from PBS's NOVA documentary strand³, looks at cutting edge research into the nature of memory, and how it might be manipulated for mankind's benefit. 

 

"For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays it intact," say the film's makers⁴. 

 

"But now, researchers are discovering that memory is far more malleable⁵, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms⁶ that can explain and even control our memories."

 

Among the documentary's subjects is Jake Hausler, a 12-year-old boy from St. Louis who can remember just about every single thing he has experienced since the age of 8. 

 

Jake is the youngest ever person to be diagnosed with Highly Superior Autobiographical Memory, which makes it difficult for him to distinguish between trivial and important events from his past.

 

"Forgetting is probably one of the most important things that brains will do," says Andre Fenton, a prominent neuroscientist who is currently working on a technique to erase⁷ painful memories. "We understand only the tip of the iceberg⁸ when it comes to human memory."
