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
