"One thing that we're really intrigued by is that this is a selective erasure," Tsien says. "We know that erasure occurred very quickly, and was initiated by the recall itself."

"But people are very interested in devising a way where you could come up with a drug to expedite a way to do that," he says. That kind of treatment could change a memory by scrambling things up just in the neurons that are active during the specific act of the specific recollection. "That would be a very powerful thing," Mayford says.

But the puzzle is an incredibly complex one, and getting to that point will take a vast amount of additional research. "Human memory is so complicated, and we are just barely at the foot of the mountain," Tsien says.

When memories will be edited in humans. Nothing will be as it used to be in human existence, no pun is meant here

Wow, you'd have to be very careful not to think of any good memories while you're on the drug though, eh?
