California, Sept. 19 -- A new study led by Stanford Medicine has revealed that the human brain develops from two distinct groups of embryonic cells, challenging the long-held understanding that the entire brain originates from a single common population of precursor cells.

The findings could transform scientists' understanding of brain development and provide new opportunities to investigate neurological diseases affecting the brainstem.
