Im Labor gezüchtete winzige ‚Gehirn‘ könnten bewusst werden und Schmerzen fühlen – und wir sind nicht bereit. Das Labor-Gehirngewebe ist zu einfach, um das Bewusstsein zu erleben, aber im Verlauf der Innovation fragen sich Neurowissenschaftler, ob es Zeit ist, die Ethik dieser Forschungslinie noch einmal zu besuchen.

„Scientists are getting closer to growing human brains in the lab, and it’s spurring an ethical debate over the welfare of these lab-reared tissues.
The debate surrounds „[brain organoids](https://www.livescience.com/minibrains-brain-organoids-explained),“ which are sometimes mistaken for sci-fi-inspired „[brains in boxes](https://sf-encyclopedia.com/entry/brain_in_a_box).“ However, these small assemblies of brain tissue grown from stem cells are too simple to function like a real human brain. As such, scientists have assumed brain organoids lack consciousness, which has led to lax research regulations.
Some scientists, however, take a different view.
„We feel that in the fear of hype and science-fiction inspired exaggeration, the pendulum has swung far too far in the opposite direction,“ [Christopher Wood](https://orcid.org/0000-0002-5517-9496), a bioethics researcher at Zhejiang University in [China](https://www.livescience.com/tag/china), told Live Science in an email. In a perspective piece published Sept. 12 in the journal [Patterns](https://www.sciencedirect.com/science/article/pii/S2666389925002132), Wood and his colleagues argued that technological advances may soon lead to the creation of conscious organoids.
The authors say regulations regarding the use of organoids should be reviewed. It would be unethical for a conscious organoid to experience its own thoughts and interests, or to feel pain, said [Boyd Lomax](https://bioethics.jhu.edu/people/profile/lomax-boyd-phd/), a neuroscientist at Johns Hopkins University.“
But somehow bringing me to the life and knowing that I will die is ethical? I think we cant let ethics to stop the scientific progression and must continue research on that topic. We all have consciousness and we all die one day so does these brains. It just doesnt matter
Honest question. Do we even know where and how consciousness works in the brain? If yes, we can avoid it and continue with the research. If not, imo we should still do this before we play god on brains.
Just sheer horror of being „awoken“ from the void just to be a lab subject in a dish is sending shivers down the spine
Ah sweet, man-made horrors beyond my comprehension.
