These Mini-Brains Could Lead to Huge Possibilities
Although they sound like one of Frankenstein’s creations, mini-brains are real. Mini-brains, also known as organoids (organ buds), are laboratory grown bundles of cells. The three-dimensional structures come from human stem cells.

Scientists use mini-brains to help study brain development as well as to understand various diseases such neurological disorders. Researchers also hope to one day use the mini-brains to test experimental drugs; thus reducing the need for laboratory animals.
Scientists are currently using two-dimensional brain models for their research. However, two-dimensional models fail to replicate the complexity of neural circuits necessary for research.
