Mini-brains grown in a lab are pushing ethical boundaries

Earlier this year, US team announced they had grown a mini-brain with neural activity similar to that seen in a preterm infant. The ability to feel or experience the world around them, may be just around the corner — and all the ethical implications it brings.

3-D human 'mini-brains' shed new light on major mental illness

Using human stem cells, researchers create 3-D model of the brain to study a mutation tied to schizophrenia, bipolar disorder and depression.

New "Mini-Brains" Could Put Thousands of Lab Animals Out of Work

Researchers at Johns Hopkins Bloomberg School of Public Health have produced tiny brains made of human neurons and cells. These mini-brains could radically change how drugs are tested, replacing the many animals currently being used for neurological scientific research.
