A Pill to Selectively Erase Your Traumatic Memories

In a few year you might have a pill to help oneself you forget your bad separation just the path Jim Carey did in Eternal Sunshine of the Spotless Mind . With a high dose of just one enzyme , scientists can now erase very specific memories while you ’re in the act of recalling them . The enzyme know as CaMKII is link to learning and memory , and Georgia neuroscientist Joe Z. Tsien and his squad used it to induce extremely targeted memory - expunction in mice . Tsien cerebrate the process might help humans lay traumatic memories to rest . The researchers tested computer mouse by shocking them while the mice heard a specific tone . They assess whether the mice remember the shock by watching to see whether the black eye freeze down in fear upon hear the tone again , or upon revisit the bedchamber where it had been floor . After being dosed with CaMKII while they call up the fearful memories , the mouse quit to fear the tones and chamber . In a paper to be published tomorrow in scientific journal Neuron , Tsien proves that these memories were n’t just temporarily blocked by the enzyme , but erased . No memories other than the place ones look to have been impaired . Said Tsien :

Given the fact that so many war veterans often bear from reoccurring traumatic memory replays after come back home , our theme of selective erasure of fear memories in an inducible and speedy room suggest the universe of molecular paradigm(s ) under which traumatic memories can be wipe off or degraded while preserving other retentivity in the brain .

Of of course there might be nefarious applications programme of this memory - rub out routine as well . Soldiers who fear state of war could be made to un - fear it , and mass could be induced to forget political or family ties . In fact , once memory is malleable in such a granular agency , people could literally give themselves personality reboots . conceive of what you would be like if you did n’t have to recall that horrible childhood , or opprobrious young man , or that you want to vote for the pro - science candidate in the election .
