According to scientists, organoids with pea size of human brain tissue may offer a way to study the biological beginnings of a wide variety of brain conditions, including autism, bipolar disorder and schizophrenia.

Scientists say that organoids with pea size from human brain tissue can offer a way to study the biological beginnings of a wide variety of brain conditions, including autism, bipolar disorder and schizophrenia.

By the time the fetus reaches the age of 6 months, it produces electrical signals that are recognized as brain waves. And clusters of lab-grown brain cells known as organoids appear to follow a similar schedule, researchers reported Thursday [19659009] in the journal Cell Stem Cell. "With these organoids in this period of six to nine months, then [the electrical patterns] starts to look a lot like what you would see with a premature baby," says Alysson Muotri, director of the Stem Cell Program at the University of California, San Diego.

The finding suggests that organoids may help scientists learn the earliest stage of human brain development and may reveal the earliest biological origins of problems such as schizophrenia and autism.

But the presence of human brain waves at the plate is likely o will also draw attention to the ethical issues surrounding this type of search.

Brain organoids (popularly known as "mini-brains") start out as just a few stem cells on a plate.

can grow into pea-sized spheres and begin to look like human brain tissue.
