Stanford researchers report evidence that the human brain develops from two separate cellular systems, indicating it may function as if it were two organs formed from ancient nervous systems with different roles. The work describes different developmental origins for parts associated with the hindbrain.
The study also enables scientists to grow human hindbrain neurons in the laboratory. Outlets highlight that this advance can support new ways to study conditions that involve the brainstem and related neural pathways, including ALS and spinal muscular atrophy. Across the coverage, the central angle is the developmental and evolutionary implication of a “two-part” brain, alongside the experimental value of being able to cultivate relevant neurons for further research.
