Scientists shrank mice's brains and replaced the missing tissue with human 'organoids': Scientists have devised a new way to incorporate human brain tissue into living mice, opening the door to new research.

Insane headline. Is it as insane as what it suggests? Are the two separate types of brain matter actually able to work with each other, or is it just as a way to see how it reacts within the body to various stimuli?

My first thought is that it could be used for more accurate testing of future meds/treatments meant for humans. For example, Alzheimer’s.

Yeah that was my imagining. The title just sounded sci fi asf

That one isnt sci fi asf, but this one is.

Fascinating.

Yea I’m not really sure how I feel about it. I mean, I know it isn’t feeling pain but it’s feeling “something” to change course. It’s creepy haha

Should have read "...opening the doors to more useless torture."

Theres a sci fi plot here that ends up with uplifted rats who dont take kindly to human BS.

And its almost as plausible as the Planet of the Apes prequels, as rodents are also Euarchontaglires. To be fair, however, two points against this would be:

  1. Other apes share a gene critical to human intelligence (which requires other genes to really manifest) which only appeared about 14 to 15 million years ago...which is well after our split from Glires

  2. I'm not sure what type of brain tissue they're incorporating or if the body would even avoid rejecting it successfully in all cases or in situations in which introduce brain tissue would increase cognition. Not only that, I believe that brain structure and not only brain tissue affects what we consider to be intelligence

Unique-Coffee5087 | 13 hours ago

The structural aspect is important. Also, they didn't just throw a bunch of brain cells in there, but organoids. I think those are already structured clusters of neurons, and so they might not be prone to reorganize themselves to integrate well with the native mouse brain

But I really haven't kept up with any of this kind of stuff in the news, and so I might not be understanding the significance of the organoid thing very well.

I appreciate the response regardless.

Every time i post in here, i get downvoted to hell for some reason, so this is a nice change of pace

Mindless0ne | 5 hours ago

giving them human brain tissue? - just see if they don't start experiments of their own, or my name isn't Slartibartfast.
