How to make a brain: new experiments challenge existing picture

Scientists have long assumed that a single type of starter cell builds the entire brain, but exciting new research suggests it actually takes two different types of precursor cells to create this complex organ. One type of cell forms the hindbrain - responsible for vital functions like heartbeat and breathing - while another generates both the forebrain and midbrain, which handle higher-order thinking. The study, published in Nature Neuroscience, challenges our fundamental understanding of brain development and reveals how these two cell populations are strictly committed to their designated regions. Beyond the theory itself, the researchers have discovered an efficient way to coax stem cells into becoming hindbrain motor neurons, which could accelerate research into devastating diseases like ALS.
