Submission + - The brain is actually two completely separate organs (stanford.edu)
Beeftopia writes: From Stanford Medicine:
"For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years."
The adult brain has three main regions: the forebrain, midbrain and hindbrain. Scientists could never create hindbrain neurons.
"Previous attempts to make hindbrain neurons likely tried to coax forebrain and midbrain progenitors into hindbrain cells, which our study shows is not possible,” said researcher Rayyan Jokhai.
"The researchers’ breakthrough came from studying the earliest moments of embryonic development, during a stage called gastrulation when the body first takes shape. Jokhai and Dundes discovered that the hindbrain follows a separate developmental path, running in parallel to — rather than branching off from — the pathway that creates the forebrain and midbrain."
With this knowledge, researchers were able to create hindbrain neurons.
