The human brain is not a single organ, but two separate systems that evolved independently before fusing together, according to groundbreaking new research. … Armed with the knowledge of how hindbrain cells uniquely form, the team has successfully turned human stem cells into becoming functional hindbrain motor neurons in a lab for the first time.
Haven’t we known this for about 3/4 century?
We knew the forebrain and hindbrain were different. This research shows that the difference is OLD, and likely from when the brain was more distributed. They also found that, while they function in almost the same way, they are built from different genetic tool kits.
Basically, we knew there was a difference. This explains what the difference is and how to work around the problems it has created.
