Remember all those dumb things you did when you were young that you'd like to forget you did? Have an ex-wife that's so aggravating you'd give anything to completely forget she even exists? Want to forget that you were dumb enough to vote for Barack Obama ... not just once, but twice? Are you a veteran with PTSD and would give anything to replace those hellish memories with more pleasant ones? Well, some day that may be possible.

[...] Researchers from the Massachusetts Institute of Technology (MIT) say the discovery could help people suffering from post-traumatic stress disorder (PTSD) by replacing "fearful" memories with more positive associations.

The gene, Tet1, has been found to play a critical role in memory extinction by controlling a small group of other genes that are necessary for the process. ...

Don't look to see this new discovery reach the treatment stage anytime soon. In years past it often took the FDA around 7 years or so to approve a new drug. In the case of this new gene discovery, much research still needs to be done, then a drug developed to activate it, then it goes to the FDA for approval. Even if the FDA agrees to fast-track the drug ... which it probably would for PTSD, it's still years away before we'll see a drug in the market that affects the Tet1 gene, if then.

However, while we're on the topic of brains, here's a couple of brain images to think about (click image to enlarge):
