Researchers working at MIT have successfully manipulated the content of a rat's dream by replaying an audio cue that was associated with the previous day's events, namely running through a maze (what else). The breakthrough furthers our understanding of how memory gets consolidated during sleep but it also holds potential for the prospect of "dream engineering."
Working at MIT's Picower Institute for Learning and Memory, neuroscientist Matt Wilson was able to accomplish this feat by exploiting the way the brain's hippocampus encodes self-experienced events into memory. Scientists know that our hippocampus is busy at work replaying a number of the day's events while we sleep a process that's crucial for memory consolidation. But what they did not know was whether or not these "replays" could be influenced by environmental cues.
To see if this could be done, Wilson and his team trained a group of rats to run through a maze using two distinct audio cues. The rats quickly learned that the tones were helpful; one sound indicated that food could be found by going left, while the other sound indicated that a food reward awaited them on the right. And while the rats were doing this, the neuroscientists were recording their neural activity.
Later, while the rats were sleeping, the researchers once again recorded the neural activity of their brains. Using correlative analysis, Wilson confirmed that the rats were dreaming of their maze navigating exploits from the day before.
But when the researchers played the audio cues from the experiment, they noticed a very interesting thing: the rats would dream about the section of the maze previously associated with the audio cue. The experiment demonstrated that the content of a rat's dream can be biased by re-activating certain memories while they're asleep.
Looking ahead, the researchers believe that this simple example of dream engineering could open up the possibility of more extensive control of memory processing during sleep and even the notion that selected memories could be either enhanced, blocked, or modified. Wilson is also aiming to develop new approaches to learning and behavioral therapy through similar kinds of cognitive manipulation.

Also, interesting name, Dvorsky... But I'd hate to have it as a nickname, as in, "That LibWhacker fella over there, been divorced ten times. So everyone calls him Dvorsky."
Obama has been stroking people’s cortex too long already.
"..and then we hung out at the docks..you caressed my tail, and I knew you had the right mites for me"
Also, “Lathe of Heaven”. Good book, so-so video adaptations. Notable for being published way back in 1971.
Good one Hoss.
Historic revisionists will get a thrill up their legs if they could one day do this...
Not only would historic revisionists love to do this, but current politicians would like to see this happen. Certain people would implant notions that they should vote for Obama, for example. You know that is what they would like to do with this sort of thing.
Too cute. Gotta show that one to my wife.
That from Dreams from my father?????
If he'd been a Ferengi, he would have caressed his ears.
Look up all the warnings about nuro sci overwelming evidence that at least 1 of an elete group in a government program in colorado went wrong namly the joker in the batman shooting ...
Already been there, done that.
Where do you think ideas of alien abduction come from?
Wait until they discover the cue that releases vague deep stored ancestral memory that leads people to believe they’ve been reincarnated.
And folks think we live in interesting times now.
I used to do this to my sleep-talking brother all the time.
It was hilarious!
I mean really, who has life threatening memory disorders?
Democrats have life-threatening memory disorders. They can’t remember that you cannot appease murderous dictators, nor that command economies always steal from the population until the resultant suffering and impoverishment is no longer bearable and the country in question undergoes a cataclysmic collapse, nor that slapping monsters on the wrist does not deter those monsters, etc. And it’s threatening our life!
