From the Ted Talk by Sergiu P. Pasca: How we're reverse engineering the human brain in the lab

Unscramble the Blue Letters

Most of the work that I’ve shown you so far has been in one specific brain rieogn. But to really understand circuits, we actually need to build more ccpilmaoted brain circuits. And so to do this, six years ago, we came up with a new approach to build hmaun circuits cealld an assembloid. Assembloids are essentially blocks of tuisse that we build in a dish from multiple organoids put together. When we put two brain organoids together, we discovered something really fnaicaitsng. First, they fesud to each other. But then they started to communicate, and brain cells from one side started to slowly migrate onto the other side and form cictrius, much like they would in the atcaul brain. In fact, we can even watch them live as they move from one side to the other. I still remember how we were in the lab in absolute awe when we saw for the first time how human cells undergo this peculiar jumping behavior.

Original Text

Most of the work that I’ve shown you so far has been in one specific brain region. But to really understand circuits, we actually need to build more complicated brain circuits. And so to do this, six years ago, we came up with a new approach to build human circuits called an assembloid. Assembloids are essentially blocks of tissue that we build in a dish from multiple organoids put together. When we put two brain organoids together, we discovered something really fascinating. First, they fused to each other. But then they started to communicate, and brain cells from one side started to slowly migrate onto the other side and form circuits, much like they would in the actual brain. In fact, we can even watch them live as they move from one side to the other. I still remember how we were in the lab in absolute awe when we saw for the first time how human cells undergo this peculiar jumping behavior.
