This pencil-eraser-sized mass of cells is something called a brain organoid.

这团橡皮大小的细胞被称为类脑器官。

Similarly, a brain organoid allows us to study different types of brain tissue, but can't think.

同样，类脑器官能帮助我们研究不同类型的大脑组织，但是它并不能思考。

A brain organoid has the same tissue types as a full-sized brain, but isn't organized the same way.

类脑器官虽然拥有与正常大脑相同的组织类型，但组织的方式却不相同。
