Can we transfer information directly from one brain to another? And then link multiple brains into a hive-mind like the Borg? Could acquire new information without having actually to learn it? Experiments on rats seem to suggest that we can transfer memories from one brain to another, even when linking them over the internet.

I’m back again! I remembered reading something about transferring memories from brain to brain

Today 21:30   

Cho

OK, go on 😏😏

Manuel

There was this experiment with rats, connected through the internet 😱😱

Today 21:34   

Cho

That was a while ago already, in 2013 IIRC                                

Today 21:35   

Manuel

Yes, indeed, so this seems to show that we can already “write” new information into the brain, right?

Today 21:35   

Cho

Well, let me unpack that experiment for you before answering  

Today 21:37

Cho

They didn’t just link two rat brain and then let one rat learn something, which was then uploaded to an untrained rat

Today 21:37

Manuel

No?

Today 21:38   

Cho

No. They trained one group of rats to press a lever if a light went on, and the other one if they got an electrical stimulus in the brain

Today 21:40   

Cho

Then they made the first rat do its task, measured the brain output, and triggered an electrical stimulus in the second

Today 21:40   

Manuel

And that isn’t the same as uploading and downloading information from one brain to the other?

Today 21:40   

Cho

It’s more Pavlov with electricity. You train a rat to react to an input, then link that to the output of another rat

Today 21:41   

Cho

That’s not really uploading and downloading information.                

Today 21:41   

Manuel

Ah, ok I think I see what you mean

Today 21:41   

Cho

And this is about a simple kind of behavior like pressing a lever, not something complex like a memory  😉

Today 21:42

Manuel

So people who are afraid of being remote-controlled through a chip can rest easy?

Today 21:44   

Cho

There is far more going on in the brain than just electrical impulses, triggering trained behavior. Mind control trough brain interfaces are not going to happen anytime soon

Today 21:45   

Manuel

Thank you for your time, this has been most instructive! 🧐🧐

Today 21:45   

Cho

Did you know they already tried this in the ’60 through brain extracts?

Today 21:46   

Manuel

WHAT 😲😲😲😲😲😲😲😲

Today 21:48   

Cho

They would train rats, extract parts of their brains, and then inject them into untrained rats                                                            

Today 21:49   

Manuel

Now you’re just messing with me … 😅😅

Today 21:48   

Cho

Oh no, I’ll give you a link. It seemed to work too …
