Episode Summary: Dr. Michael Levin talks about cognition manifesting at scales beyond brains, including in cells and tissues via bioelectric networks; analog vs. digital coding in biology; how bioelectric patterns guide development and regeneration (e.g., in planarians); creation of novel life forms like xenobots and anthrobots; philosophical ideas on a "platonic space" of mathematical patterns influencing biology; evolutionary trade-offs in regeneration and implications for regenerative medicine.
About the guest: Michael Levin, PhD is a biologist and computer scientist who directs the Allen Discovery Center at Tufts University, focusing on bioelectricity, regeneration, and cognition in non-neural systems.
Discussion Points:
Cognition isn't limited to brains; tools from neuroscience reveal learning, memory, and goal-directed behavior in cells and tissues.
Bioelectricity acts as "cognitive glue," enabling collective intelligence in non-neural systems, predating multicellular life.
Analog coding in development uses slow voltage patterns across cells, contrasting fast digital spikes in neurons.
Planarians regenerate perfectly due to bioelectric "memories"; altering patterns creates stable two-headed worms without genetic changes.
Regeneration trade-offs: Mammals prioritize quick healing over full regrowth due to infection risks and load-bearing needs.
Xenobots (from frog cells) and anthropots (from human cells) self-assemble, replicate, and heal tissues, revealing untapped cellular potentials.
Patterns in biology may stem from a "platonic space" of mathematical truths, not just evolution or physics.
Neuroscience studies mind scaling, not just neurons; diverse intelligences could exist in non-cellular systems.
