Scientists create mice with part-human brains

Researchers hope to shed light on conditions such as schizophrenia, epilepsy, cerebral palsy, intellectual disability and rare forms of dementia

Researchers have created mice with half-human brains in an effort to understand and develop new treatments for disorders such as schizophrenia, epilepsy, cerebral palsy, intellectual disability and rare forms of dementia.

The scientists transplanted lab-grown human brain cells into animals that were engineered to be born without a cortex or hippocampus. This made space for the human tissue to grow inside the rodents’ skulls.
