Brain Organoid Transplants and Cracking the Autism Code

Researchers have successfully transplanted human cortical organoids into specially engineered mice lacking most of their cerebral cortex, allowing the human tissue to integrate into the mouse nervous system and improve motor function. This breakthrough, termed "xenocortication," provides a new way to study human brain development and neuropsychiatric conditions by making previously inaccessible biology experimentally accessible. The study highlights the significant neuroplasticity of the developing nervous system and has sparked discussions about the need for international oversight of such research.
