Human Neurons Continue to Migrate After Birth.
Scientistis used to think that neurons in the human brain were pretty much set in place before birth.
In 2011, The University of California, San Francisco researchers found a few small groups of neurons still migrating after birth.
Now, new research has uncovered a mass migration that continues up to 3 months after birth.
These neurons are migrating to the cerebral cortex, the part of the brain responsible for advanced cognition.
It happens at the same time infants begin interacting with their environment.
The vast late migration is not seen in other mammals.
Researchers believe this may contribute to the uniqueness of complex human cognition.
