This is some serious crazy science awesomeness!!
Researchers have grafted human brain cells into the brains of mice!
They then tested learning and memory in the mice.
The mice outperformed their non-human-cell-enhanced counterparts!
This shows that it's kinda less about the size of the brain in relation to the body, and more about what's going on in the human brain at a microscopic level.
One of the reasons that the mice could've gotten smarter is because human brain cells are just more efficient.
Cause we're da best!
The researchers said:
"This is incredibly interesting work which strongly suggests that human astrocytes are indeed enhanced in their ability to control synapses compared to mouse astrocytes. They have not shown that the astrocytes are expressing their normal gene profile, and the enhanced cognitive performance could be because of the persisting precursor cells."
Basically all that means is humans rule!!
We wanna put human brain cells into dogs so we can have super smart buddies who can cuddle and watch TV with us and actually understand what's going on!
C'mon, science, get on it!
