Your brain may be one organ today, but scientists have uncovered a hidden split that may date back more than 500 million years

New research suggests the human brain develops from two distinct cell populations. These groups follow separate paths from early embryonic development stages. This finding challenges long-standing assumptions in neuroscience and evolutionary history. Scientists used this discovery to create functional hindbrain motor neurons in the lab. This breakthrough offers a new model for studying neurological diseases like ALS and SMA.
