Scientists Grow Working Human Brain Circuits


Researchers at the Stanford University School of Medicine have successfully grown the first-ever working 3D brain circuits in a petri dish. Writing in the journal Nature, they say the network of living cells will allow us to study how the human brain develops.

Scientists have been culturing brain cells in the lab for some time now. But previous projects have produced only flat sheets of cells and tissue, which can’t really come close to recreating the three-dimensional conditions inside our heads. The Stanford researchers were especially interested in the way brain cells in a developing fetus can join up together to create networks.

“We’ve never been able to recapitulate these human-brain developmental events in a dish before,” senior author Sergiu Pasca, MD said in a statement.

Studying real-life pregnant women and their fetuses can also be ethically and technically tricky, which means there’s still a…
