Scientists Insert a Synthetic Memory Into the Brain of a Sleeping Mouse
the_newsbeagle writes: Scientists are learning how to insert fake memories into the brain via precise electrical stimulation (abstract). In the latest experiment, they gave sleeping mice a synthetic memory that linked a particular location in a test chamber to a pleasurable sensation. (At least they gave the mice a nice memory.)
The researchers first recorded the electrical signals from the mice's brains while the mice were awake and exploring the test chamber, until the researchers identified patterns of activity associated with a certain location. Then, when the mice slept, the researchers watched for those neural patterns to be replayed, indicating that the mice were consolidating the memory of that location. At that moment, they zapped a reward center of the mice's brains. When the mice awoke and went back into the chamber, they hung around that reward-associated location, presumably expecting a dose of feel-good.

Very early in the research, but man would this be a cool alternative to education. Take a nap, ready to start your PhD Thesis.

First when K flashes Beatrice after she saw her "husband" inhale the sugar water, and later at the morgue, when K instructs the clean up crew to give the coroner a happy memory.

Things like this will never get exploited by opportunistic Intelligence Agencies.
Let's sit back and watch them scramble over themselves to justify why they need this tech.
Yes slightly offtopic, but I bet they are funding the research.
It doesn't seem like what they did is really creating a "synthetic memory". It's taking an existing memory, and attaching (or perhaps even just re-enforcing) an emotion to it...
The memory of the place is the same, they just remember enjoying it more than they did at the time.
As a human you could do the same thing by visiting a famous place, then reading a really good story set there. Your own recollections of the place would have a fonder cast if you were even more excited about having been there.

Wake me when they can zap a mouse and it can get to someplace it's never been before.
This, along with the already known way to simply wipe-out certain memories, can go a long way towards establishing the "Right To Be Forgotten". Your ex, for example, may be able to obtain a court order for you to undergo the procedure to remove your memories of all the good times you had together...
Or, if that seems too draconian, have those memories replaced by your taking a hike or flying a kite...
In Soviet Washington the swamp drains you.
Why only when they remember bad things? After all, if they are a Bad Person(TM) then they don't deserve to do the things they enjoy like listening to Beethoven.
If I have been able to see further than others, it is because I bought a pair of binoculars.
So stupid. Can you imagine hanging around a place waiting for a pleasure signal? Animals are so... wait a second, got to check the FaceTwitterSlashFark feed... nothing new, darn. Anyhow, animals are so... ooh, new update!
Developing habits is arguably the most important form of education there is.
It's not just about eating your veggies and going to the gym; habits intrude on things which we normally think of as the domain of rational thought. If you hear somebody who disagrees with you do you rationally weigh his arguments or automatically dismiss them? What determines which of these alternatives you choose is habit.

Can someone zap the pleasure centers in my brain while I'm looking at a picture of a treadmill? Or better yet, am ON a treadmill?
Occasionally living proof of the Ballmer peak.
Didn't /. run an article on this before? Wait a minute, am I maybe part of the experiment...?
The IRS is funding this research with the hope of getting tax payers to look forward to paying their taxes, more often, larger, bigger, huger! Pretty soon you'll want to shovel your money into the IRS pockets so that you can feel that pleasure. It will be better than sex, better than chocolate. There will be a resulting reduction in world obesity and population.
