Melanoma conversion is all-or-none at animal level despite population variation

In tadpoles with disrupted bioelectric signaling: different reagents produce 0-100% conversion rates in populations, but individual animals are entirely converted or entirely normal—collective decision-making phenomenon.

Claims (2)

claim

Bioelectric signaling is a primary modality for coordinating cells into morphogenetic collectives
supports
Voltage gradients and gap-junctional communication coordinate large-scale anatomical decisions in development and regeneration, prefiguring neural coordination.
Collective intelligence exists on a spectrum across biology from cells to organisms
supports
Authors argue no sharp distinction exists between familiar animal cognition and collective behavior in cells/tissues; same principles apply across scales and substrates.

community

Bioelectric morphogenesis & anatomical intelligence
members_of
Levin-led research showing bioelectric signals encode and control anatomical goal states in living systems.
Bioelectric state as morphogenetic collective decision
members_of
Cellular bioelectric patterns encode organ identity and developmental decisions at population level, demonstrated through drug/ion channel interventions that toggle phenotypes in all-or-none fashion (Levin group, 2009-2017).

Methods (2)

method

Ion Channel Misexpression and Chemical Activation
supports
Experimental technique to induce bioelectric state changes and measure consequences for collective decision-making (morphogenesis, cancer, organ formation).
Machine Learning-Based State Space Modeling
supports
AI-discovered pathway models that reconstruct decision landscapes and enable prediction of novel interventions in collective decision-making systems.
