"Two months ago, history was made when [scientists] were able to put a memory directly into a mouse. This is the first time in history it has been done — it's something right out of science fiction. What they did was, they looked at the hippocampus of a mouse, and tape-recorded impulses as it learned a task. That's the gateway for memory: All memories first go through the hippocampus. They tape-recorded the impulses. Then they gave it a chemical which made the mouse forget the task. Then they took this tape-recording, shot it back into the mouse, and the mouse immediately knew how to do the task.

"This is the first time it has been demonstrated that you can actually tape-record a memory and then reinsert the memory into a mouse and have the mouse perform the task that it previously forgot. The implications of this are enormous. ... It means that memories, in principle, might be tape-recorded and then shot right back into your brain or somebody else's brain."

If I'm not mistaken they played it back in the same mouse, with the same exact neuronal pattern. I'm not sure it would have worked if replayed into another mouse.

Obviously, that's the next step in the research. Record a memory from Mouse A, play it back into Mouse B's brain, and test B to see if it has the knowledge of A.

I'm hardly a scientist and i can't watch the video right now, but how do they know the forgetfulness compound was completely effective?
