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."

    being wiped by the cia, the nsa or homeland security, we've got the link to prove it.

    ah, i feel vindicated. one of my paranoid thoughts is that people have their memories wiped of certain things they've done, knowing that science has reproduced it in mice means time travelers from the future could easily have been doing it for years now.

    well, just as soon as the time machine gets proved to be possible. quantum physics is dangerously close to that with 'particles being everywhere all at once, until observed.' how can a quantum particle like a photon be everywhere all at once, until observed, unless time travel is also possible on the quantum level.
