Study Notes
Podcast Summary: Consciousness in Lab-Grown Brains
- Lab-grown mini-brains (cerebral organoids) are being studied
- Made from stem cells, creating 3D balls of brain tissue
- These structures are similar to developing human brains in certain ways
- Madeline Lancaster, a researcher, grew a brain organoid in 2010
- Organoids currently can't grow exceeding a centimeter
- They lack the complex internal structures of fully developed brains
- Researchers are exploring the ethical concerns about lab-grown brains becoming conscious
- Anil Seth, a neuroscientist, believes it's possible for organoids to develop consciousness
- The complexity could be similar to humans, but our understanding is limited
- How to determine consciousness in organoids is a significant challenge
- The real challenge is that they are isolated mini-brains lacking natural behaviour
- Measuring electrical activity is compared to conscious states in humans
- Assessing human consciousness is complex, using electrical activity and brain imaging
- New ethical guidelines are needed for this emerging technology
Ethical Concerns
- If organoids experience suffering, that raises concerns in the scientific community
- There is no definitive way to assess the consciousness of organoids
- Organoid technology is rapidly developing
- Ethical frameworks need to be developed proactively for future concerns
- A committee of the National Academies is examining ethical issues in organoid technology
- Jeantine Lunshof, a philosopher, believes its premature to regulate organoid research
- Many aspects, like the origin of cells, are already subject to regulation
- The organoids’ appearance resembling mini-brains may influence moral judgements
