Do we really have two brains? Stanford research offers a surprising answer

A new study led by Stanford Medicine found that the brain is "two separate organs adjacent to one another". The finding, published in the journal Nature Neuroscience on September 18, 2026, claims to help improve research into "devastating neurological diseases". Scientists have struggled for decades to grow certain types of brain cells in the laboratory, but Stanford University's latest research opens the doors to studying brain-stem related diseases, such as spinal muscular atrophy spinal muscular atrophy (also known as SMA) and amyotrophic lateral sclerosis (also known as ALS or Lou Gehrig’s disease) and amyotrophic lateral sclerosis (also known as ALS or Lou Gehrig’s disease).
