Lab-grown brain models gain a sense of place
Researchers at the University of California, Irvine, have successfully engineered lab-grown brain organoids that exhibit regional identity, mimicking the front or back of the human cerebral cortex. This breakthrough provides a new model for studying brain development and neurodevelopmental disorders.
Why it matters
This advancement offers a powerful tool for understanding complex brain organization, which could lead to better treatments for developmental conditions.

DOI: 10.1016/j.stem.2026.07.014 The human brain is often described as one of the most complex structures in biology, and much of its power comes from how it's organized. Its outer layer, the cerebral cortex, is not one uniform sheet. As the brain develops, it divides into distinct areas that each take on different jobs, from movement and vision to memory, language and social understanding.
Scientists call this process "arealization," and they believe it underpins much of what the brain can do. It may also help explain what goes wrong in some conditions that affect brain development.
