science 🧠 Human brain might be two separate organs
Stanford scientists suggest the human brain is actually composed of two distinct systems that evolved apart. This research found that one system handles survival functions like breathing, while the other manages complex thought processes. The findings, published in Nature Neuroscience on Sept. 18, challenge the old theory of a single brain origin. This discovery could unlock new ways to study brain stem diseases like SMA and ALS. Researchers successfully grew functional human hindbrain motor neurons in the lab using this new knowledge.
