claim:pattern-memory-in-planaria-can-be-re-written-non-genetically-via-transient-modification-of-membrane-potential-leading-to-permanent-changes-in-target-morphologyPattern memory in planaria can be re-written non-genetically via transient modification of membrane potential, leading to permanent changes in target morphology.
Summarizes the two-headed planarian phenomenon.

- Experimental evidence that organism-scale goals can be rewritten through physiological signals without genetic modification; demonstrates bioelectricity as cognitive medium.
- Testable by computational modeling and experimental perturbation of specific bioelectric circuits.
- Key empirical result demonstrating a sharp distinction between the cellular machine and the data it uses, analogous to false memory inception
- Planaria maintain memories and re-imprint them from tail fragments onto newly regenerating brains.finding0.826Example of memory dynamics during extreme regeneration.
- Interpretive claim explaining planarian robustness as top-down morphogenetic intelligence.
- Transient bioelectric perturbation with ion channel drugs/RNAi permanently alters the number of heads regenerated even in subsequent rounds without further treatment, demonstrating bioelectric pattern memory.
- Key evidence that morphogenetic memories are stored in bioelectric circuits and are rewritable via transient voltage state modifications; memory persists across multiple regeneration cycles.
- Demonstrates that anatomical outcomes can be reprogrammed at the bioelectric level independently of DNA, inverting the software/hardware metaphor
