Stem Cells to Brain Models: The Science of Brain Organoids

What are brain organoids? In this video, Insoo Hyun, Director of the Center for Life Sciences at the Museum of Science, explains these pea-sized models of the developing human brain. Created from stem cells, they can help us understand brain development and brain diseases through tests and research. However, they don’t have consciousness: the only have 2 to 3 million cells, whereas the human brain has 100 billion cells. What questions do you have about brain organoids?
