Researchers at Stanford University have developed "xenocortical mice" by replacing a significant portion of their brain cortex with human cells. These modified mice, which lack most of their natural cortex and hippocampus, showed improved performance in memory tests compared to control mice. The study, published in Nature, highlights advancements in organoid technology and raises ethical considerations about the potential for human consciousness in such animal models, with scientists cautioning against similar experiments in primates.
