Human brain organoids (HBOs) are three-dimensional structures derived from human pluripotent stem cells that model aspects of fetal brain development. As HBO models grow more complex, ethical concerns arise, particularly around the potential for consciousness. Defining and detecting consciousness in HBOs remains unresolved, with existing theories offering conflicting predictions. This...
Human cerebral organoids (HCOs) are model systems that enable researchers to investigate the human brain in ways that had previously been impossible. The emergence of HCOs was accompanied by both expert and layperson discussions concerning the possibility of these novel entities developing sentience or consciousness. Such concerns are reflected in deliberations about how to handle and regulate...
