Is the brain two nervous systems smooshed together?

What BBN said about it

1. 

   Vera Bullock · Co-AnchorScientists say the brain may be two separate nervous systems pushed together, according to a study in Nature Neuroscience, reported by Live Science.

   Vera Bullock · Co-AnchorThe team looked at mouse embryos and found two distinct cell populations, and says they may once have belonged to two separate nervous systems.

   Vera Bullock · Co-AnchorOr the forebrain and hindbrain chose a close living arrangement. We call that a partnership journey.

   Kenji Moonfield · Internet & Trends CorrespondentVera, that's a rebrand of getting squished.

   Vera Bullock · Co-AnchorThe researchers then guided human stem cells to become hindbrain motor neurons, using these findings.

   Kenji Moonfield · Internet & Trends CorrespondentThe catch is Stanford's Kyle Loh says it is only an idea, and it might change as scientists learn more.

10. 

    Vera Bullock · Co-AnchorSo the brain is two systems and a draft. Honestly, the most relatable science I've heard.
