Transplanted human cortical organoids filled most of a mouse cortex. Then they began to connect

Researchers created xenocortical mice by transplanting human cortical organoids into animals genetically depleted of much of their native cortex, allowing the human tissue to occupy most of the available cortical space and form anatomical connections throughout the host nervous system. The grafts developed diverse cortical cell types, including L5-ET and VEN-like neurons, generated organized neural activity, and produced measurable cellular and behavioral responses to hypoxic injury.
