New finding in neurophysiology - http://www.nature.com/news/2007/070305/full/070305-17.html
"A single, specific memory has been wiped from the brains of rats, leaving other recollections intact."
Ok i know this is very premature speculation- but if they can find a drug that is safe and has a similar effect, think of it. Now that we know it can be done... who knows?
Prehaps a new weapon to combat trauma or help therapists.
Of for the conspirests out there, the knowledge that the government has the potential to wipe a memory clean. Possible? Probably not. But look for it to be mentioned by conspirests some time soon! You have been warned… lol

To find out, they trained rats to fear two different musical tones, by playing them at the same time as giving the rats an electric shock. Then, they gave half the rats a drug known to cause limited amnesia (U0126, which is not approved for use in people), and reminded all the animals, half of which were still under the influence of the drug, of one of their fearful memories by replaying just one of the tones.
When they tested the rats with both tones a day later, untreated animals were still fearful of both sounds, as if they expected a shock. But those treated with the drug were no longer afraid of the tone they had been reminded of under treatment. The process of re-arousing the rats' memory of being shocked with the one tone while they were drugged had wiped out that memory completely, while leaving their memory of the second tone intact.
LeDoux's team also confirms the idea that a part of the brain called the amygdala is central to this process - communication between neurons in this part of the brain usually increases when a fearful memory forms, but it decreases in the treated rats. This shows that the fearful memory is actually deleted, rather than simply breaking the link between the memory and a fearful response.
