Mini-brains grown in a lab show neural activity like preterm babies

September 09, 2019

Miniature brains grown in a lab exhibit remarkably similar activity to preterm babies’ brains. This dispels the idea that human brains need to develop in a womb or be connected to other organs to function. Scientists have long been trying to grow realistic models of human brains to better understand how our brains work and make it easier to test new treatments for neurological disorders.
