Scientists say that pea-sized human brain tissue organoids could provide an opportunity to study the biological origins of a variety of brain diseases, including autism, bipolar disorder, and schizophrenia.

Scientists say that pea-sized human brain tissue organoids may provide a way to study the biological origins of a variety of brain diseases, including autism, bipolar disorder, and schizophrenia.

When a fetus is 6 months old, it generates electrical signals that are recognizable as brainwaves.

And clusters of human brain cells known as organoids appear to follow a similar schedule, researchers report Thursday ] in the journal Cell Stem Cell.

"After these organoids range from six to nine months, [the electrical patterns] looks like a premature baby," says Alysson Muotri, director of stem cell program at the University of California, San Diego ,

The results suggest that organoids can help scientists study the earliest phase of human brain development and may reveal the earliest biological origins of problems such as schizophrenia and autism.

But the presence of human-like brainwaves in a bowl will probably also pay attention to the ethical issues that affect this species of re search.

Brain organoids (commonly referred to as "minibrains") begin as few stem cells in a shell.

However, with the right support from researchers, they can grow into peas the size of a pea and begin to look and behave like human brain tissue.
