Would you take pills to forget bad memories of your past? That's what new research from the University of Georgia may eventually promise.  (Source: Wired)
With new medicine you may soon be able to choose to wipe your memories -- but is it a choice you want to make?

Scientists are gaining impressive new insight into the brain and nervous system of late.  New experiments in neuron signaling could one day return movement to victims of paralysis.  And the next generation of computer controllers are already tuning in to our brain waves.  New technology even promises to reverse memory loss.

Now a radical new technology may dramatically alter life as we know it.  The Georgia College of Medicine has invented a chemical treatment that molecularly wipes traumatic or intense memories.  The chemical, successfully tested on lab mice, could be adapted to human physiology according to research and could one day be available to treat a variety of psychological ailments or even for elective use.

The approach targets a specific chemical in the brain.  This chemical, a protein, plays a crucial role in the formation of memories.  When recalling a specific painful event, a drug developed by the researchers overloads this mechanism, causing an excess of the protein to be produced.  This causes the brain to overload and chemically wipe all trace of the negative memory, without any apparent physiologically harmful side effects.

Scientists say that the treatment could be applied to humans and could one day wipe memories of traumatic events, a common cause of psychological problems.  While the researchers caution that memories are an important part of the learning process, they also acknowledge that some memories cause the mind more harm than good.

Dr. Joe Tsien, of the Brain and Behaviour Discovery Institute in Georgia comments, "First of all I should emphasise the methodology is not applicable to the human clinical situation yet.  However, it does suggest molecular paradigms which we can explore to perhaps achieve the same kind of effects in humans - but those are probably years or decades away."

He comments that war veterans, "often suffer from reoccurring traumatic memory replays after returning home".  A pill version of the memory wipe chemical could one day eliminate these traumatic flashbacks.

The new medicine bears uncanny parallels to the fictional movie "Eternal Sunshine of the Spotless Mind" in which Kate Winslet and Jim Carrey play two characters formerly in love who decide to wipe their memories of each other.

Dr. Joe Tsien warns, though, that if the treatment should ever be adapted for the human physiology, people should use it with caution.  He describes that most memories are useful, but a few can be harmful. "If one got a bad relationship with another person, hoping to have a pill to erase the memory of that person or relationship is not the solution.  (But) while memories are great teachers and obviously crucial for survival and adaptation, selectively removing incapacitating memories, such as traumatic war memories or an unwanted fear, could help many people live better lives."

The scientists used a special chamber to test the memory wipe.  A sound would play and mice would receive a mild, slightly painful shock.  The mice became alarmed when they would hear the noise.  Giving the mice the "memory protein" alpha-CaMKII, also found in humans, when the mice were not hearing the sound did nothing, apparently because the mice were not accessing the memory.  However, when the researchers played the sound and administered excess levels of the protein, the memory of the mice was wiped.  This was evidenced by repeated trials which showed the memory wiped mice to be unafraid of the sound when normal mice started panicking.

While many may be curious of how the new technology might affect life, Dr. Tsien reminds that it will take time to adapt to the human physiology.  He states, "No one should expect to have a pill do the same in humans any time soon, we are barely at the foot of a very tall mountain."

And yet, the new research takes the prospect of human memory wipes from the realm of fiction to ongoing research, and in doing so raises key social, moral, and ethical quandaries.

This can be turned by criminals to use it to wipe evidence of their traumatized victim?
For example, will such a drug be powerful enough to wipe the memory of a witness whom witnessed the murder and hence be exploited by the killer?
Perhaps a criminal can force-feed such a drug to the victim of rape?

Until an actual human trial we will have no idea how deep and accurate this really it.

Bob may remember Jack robbing him but just can't recall how. Or something like that.

The real can of worms is when they start injecting memory...

not taken into account....

the recency of the memory. i'm sure something that happened in the past 24 hours is a lot more volitile than a memory from 24 years ago.

it would seem very delicate to extricate 1 negative memory from ages past without causing loss of other memories adjacent to it (either chronologically or categorically).

i remain unconvinced. may i remind you the human mind is the only animal species with a cerebral cortex; and that mind is infinately more complex than that of a purely instinctive creature--such as a labrat.

Dr: Do you know who you are?
???: No.
Dr: You are Subject01.
Subject01: I am Subject01.
Dr: Do you remember anything?
Subject01: No.
Dr leaves the room.
Dr: We have sucsess sir.
???: Now beging the retraining.

Well it seems that my point was missed as I was rated down on that post. So I will say it more clearly. Our memories are part of who we are good, bad/tramatic or other. If we start messing with them we run the risk of losing who we are. Just take a look at someone with advanced alzheimers, the cases that I have seen they are not the same person as before.

actually i believe your comment was rated down because of the very awkward spelling errors.

Actually the rat has a cerebral cortex. In fact, rats and mice share far more stretches of DNA with humans than dogs or cats. 85% of the DNA in humans and rats are the same and 90 percent of genes linked to diseases are the same. This is why rats are used for medical research.

It's only illegal if you get cought.

And if your smart enough to get around getting cought, more power to you.

as far as i'm concerned this is a biological weapon and related research should be terminated.

it's one thing to understand how the brain works, its another to alter it in ways that could be used as a weapon. i can't believe this is actually happening.

Don't worry Samus, the human mind is extremely more complex than a mouse, so it may not work at all. Moreover, notice that the mouse had to be actively undergoing the trigger for the memory (the sound) for this to work. There is only a small window of opportunity framed around when the animal is actively trying to remember.

A good question is whether this is erasing the memory, or the trigger. There are some cases of trama that have multiple triggers, which is why it takes years of treatment and figuring out what all the triggers are and learning to control them/overcome them. They should try to have multiple triggers going at once and then see if they are jsut erasing one of them. there is countless numbers of tests that would have to be done before this could ever be thought of being used on humans.

Also, one thing i think of is that there is protien writing going on from the drug. It's not preventing anything, but altering. We have no idea if the trigger was just turned into something else (a different sound, a site, a smell?) that will manifest itself later on in an unpredictable way. This is very dangerous indeed.

It is spelled "caught".

And what a terrible attitude to have. Rapists will love this pill. They can wipe any memory of what they did from their victims if this delivers as promised.

Or if you get caught.

While theoretically possible, that scenario is completely impractical. This would require a criminal to steal a hard-to-find, very expensive drug, force the victim/witness to take it, and hope it actually works properly.

Simply putting a bullet in the witness/victims head is so much cheaper, easier, and has a much higher chance of success. Why try new, exotic methods when the tried and true ones work just fine?
