Scientists at the University of Wisconsin-Madison have 3D-printed brain tissue that works and grows just like the real thing. Their mind-blowing breakthrough revolves around novel tissue structures that are strong yet thin enough for neurons to grow on them and communicate. 

Growing brains in a lab may sound like a sci-fi plot, but the team is very serious about turning their discovery into a platform for future studies. With further R&D, it’s thought the tissues could be used to develop treatments for neurological disorders like Parkinson’s or Alzheimer’s. 

“This could be a hugely powerful model to help us understand how brain cells and parts of the brain communicate,” enthused Zhang Su-Chun, a professor of neuroscience and neurology at UW–Madison. “It could change the way we look at stem cell biology, neuroscience, and the pathogenesis of many neurological and psychiatric disorders.”
