Claims (1)
claim
- The subject of memories and preferences is not fixed but undergoes radical substrate remodeling during lifetime; demonstrated by metamorphosis, regeneration, and bioengineering examples.
Hypotheses (1)
hypothesis
- Hypothesis that memories can persist and be reimprinted on new substrates during metamorphosis, regeneration, and brain replacement; tested in planaria and butterflies.
Communities (3)
community
- Gap junctions and bioelectric signals encode body-plan and memory patterns across radical biological transformation.
- Transient bioelectric manipulation persistently alters head number and patterning despite wild-type genetics in planaria.
- Investigates how memory persists across decapitation and brain regeneration in planarians, questioning substrate of consciousness.

- Worms trained before decapitation re-acquire the memory after regenerating a new brain, showing transfer of information across tissues.
- Cited empirical result supporting persistence of self/memory through structural regeneration.

- Evidence that memory and anatomical form are tightly linked; information processing enables integration of behavioral and morphological change.
