Mice engineered with human brain cells spark breakthrough in brain disease research
TL;DR Summary
Stanford researchers transplanted human brain organoids into mice with greatly reduced cortex, enabling human cells to integrate with the mouse brain and circuits. The animals showed largely normal behavior, offering a potential new model for studying human brain disorders and testing treatments, but the work does not make mice think like humans and raises significant ethical questions about animal cognition and welfare.
