Scientists make significant brain breakthrough — and it could change how humans treat diseases

Researchers at Stanford University have upended fundamental assumptions about human brain development, revealing today what humans consider a single organ is actually two entirely separate systems that evolved independently.The breakthrough discovery, published in Nature Neuroscience, demonstrates the forebrain and midbrain develop from completely different progenitor cells the hindbrain, contradicting the longstanding belief that all brain tissue originates from one master parent cell.The finding emerged whilst scientists attempted to solve a persistent laboratory mystery: whilst cells from the frontal brain regions could be cultivated with relative ease, brain stem cells proved nearly impossible to grow in laboratory conditions.Through...
