A research team in Japan has successfully recreated key human neural circuits in the laboratory using tiny, multi region brain models called assembloids. These structures are grown from induced pluripotent stem (iPS) cells and are designed to mimic how different parts of the human brain connect and communicate.

Using this system, the scientists showed that the thalamus plays a central role in shaping specialized neural circuits within the human cerebral cortex. The study was published in the journal Proceedings of the National Academy of Sciences of the United States of America.
