Scientists Erase Specific Memories In Mice

Ostracus writes "It sounds like science fiction, but scientists say it might one day be possible to erase undesirable memories from the brain, selectively and safely. After exposing mice to emotionally powerful stimuli, such as a mild shock to their paws, the scientists then observed how well or poorly the animals subsequently recalled the particular trauma as their brain's expression of CaMKII was manipulated up and down. When the brain was made to overproduce CaMKII at the exact moment the mouse was prodded to retrieve the traumatic memory, the memory wasn't just blocked, it appeared to be fully erased."

    undesirable for whom? While this might positively applicaple for e.g. victims of rape there are tons of possible missuses which really should be feared.

    All memory of Goatse could be erased! That has to count for SOMETHING.

    No, it's not happening. That's insane. Besides, I'm sure there would be some after effects like brain damage.

    I tell you where else this would be a positive thing - in erasing the memory of good books/films/video games, so that you can experience them all again as if for the first time. I would love to be able to re-experience the magic of reading some of my favorite fiction as if for the first time.

    Lister: What for?
    Holly: Well, if you erase all the Agatha Christie novels from my memory bank, I can read 'em again tonight.
    Lister: How do I do it?
    Holly: Just type, "Holmem. Password override. The novels Christie, Agatha." Then press erase.
    Lister: I've done it.
    Holly: Done what?
    Lister: Erased Agatha Christie.
    Holly: Who's she, then?
    Lister: Holly, you just asked me to erase all Agatha Christie novels from your memory.
    Holly: Why should I do that? I've never heard of her.
    Lister: You've never heard of her because I've just erased her from your smegging memory.
    Holly: What'd you do that for?
    Lister: You asked me to!
    Holly: When?
    Lister: Just now!
    Holly: I don't remember this.

    Well, technically it is a form of brain damage. Though I'm sure it'd be on par with, say, a night of heavy drinking.

    "Shift."--you put the closing quote after the period.
