On a somewhat related note, I had a professor who was a working psychiatrist who related to us some stories from his days as a lab assistant in the 70's and he said that they'd managed to prove that memory floats around in a liquid state for up to an hour and circulates throughout the brain.
The experiment involved putting rats on an elevator that took them to a platform that would shock them if they left the elevator. Apparently if you do this to a rat, and within a certain amount of time, cut open it's head and extract some liquid or another (I think he said they were taking RNA, but I know nothing about biochemistry) and inject it into the head of another rat the receiver would hide in the elevator once it took him to the electrified platform.
I have no idea how well I've accurately stated this information, it was shared rather loosely as an anecdote, he didn't get into specifics, and I'm not capable of comprehending them at any real depth as it is...but it still was interesting.
