Stanford Scientists Challenge Long-Held Theory Of Brain Development

Their findings indicate that the forebrain and hindbrain follow separate developmental pathways during embryonic formation, challenging a long-standing understanding of how the brain develops.

Researchers at Stanford Medicine say they have uncovered evidence that the human brain developed from two distinct cellular origins rather than from a single developmental source.

Their findings indicate that the forebrain and hindbrain follow separate developmental pathways during embryonic formation, challenging a long-standing understanding of how the brain develops.

💡
The two regions perform very different roles. The hindbrain controls essential automatic functions such as breathing and heart rate, while the forebrain supports complex abilities including language, reasoning and other higher cognitive functions.

Scientists say the discovery could improve laboratory models of brain development by allowing researchers to study the two regions more accurately in cell cultures.

This could eventually support research into neurological disorders, including diseases such as ALS and spinal muscular atrophy. Evolutionary analysis suggests the two brain regions can be traced to a distant common ancestor more than 500 million years ago, offering a new perspective on the evolution and development of the human brain.
