Neuroscientists in the US have successfully adapted mice to have functioning human cells inside their own brains.
The researchers hope that potential treatments for psychiatric and neurodevelopmental diseases that only occur in humans could now be tested on the laboratory rodents.
While mice with brains that are partly human might sound like a Kafkaesque experiment, the scientists said these are not "mice that think like humans".
The animals are genetically engineered - and surgically altered - so that some of their brain tissue is human.
...
First, they genetically-engineered mice to develop almost none of their own cerebral cortex – that is the outer layer of the brain sometimes referred to as "grey matter". It handles higher-level thinking, memory and senses.
The researchers then used skin cells taken from humans and "reprogrammed" them, so they grew into pieces of brain-like tissue.
These are structures called organoids – they are not whole brains grown in dishes, more collections of connected, living cells.
When these organoids were implanted into the mouse brain the cells divided and organised themselves into the animal's existing brain circuitry, connecting with the rest of the mouse's brain and spinal cord.
The cortex of the implanted mice is not perfect - normal cortex forms organised, structured layers. And as neuroscientist Dr Ilary Allodi put it, scans of these human-mouse brains look "a bit messy".

Well, that will increase the IQ of the DNC’s Useful Idiots
There’s no need for that. We have enough mouse brains exhibited by many who are supposed to be human.
Finally the Secret of NIMH will become a reality.
Someone really should make a movie about all this.
Male or Female ?
old news... Mouse sized brains have been around forever. ...and here these guys are thinking theyre all that...
This could put a new twist on the old question: “Are you a man or a mouse?”
An abomination!
It’s analogous to when people ask me if I am a northerner or a southerner. I say ‘ah oo no, I grew up in maryland just outside of DC.’ My wife who grew up in soviet michigan calls me a confused southerner.
As I read this, I too wondered to myself if this could help leftists.
I catch a lot of mice around the homestead. Predictable. Offer free food and SNAP! goes the trap. They’re dead.
There’s a lesson or a parable or something in this.
Mouse brain matter will not help the leftists. They are already susceptible to free stuff. SNAP! goes the trap.
This will advance cheese production.
Now they can point, click and chew gum all at the same time!
What could possibly go wrong?!
