Claims (3)
claim
- Morphogenesis is an example of basal cognition, a collective intelligence of cells navigating morphospace.associated_withAsserts that developmental biology can be understood through the lens of problem-solving and cognitive concepts.
- Planarian head number can be permanently altered by re-writing bioelectric prepatterns.
- Summarizes the two-headed planarian phenomenon.
Concepts (5)
concept
- Bioelectricityassociated_withimplementsProposed 'cognitive glue' common to both neural and developmental collective intelligence; implemented by ion channels and electrical synapses.
- patternsrelated_toDesigns containing a repeating motif
- Bioelectric pattern memoriesextendsStable voltage distributions that encode target morphologies and can be re-written, functioning as memory in cellular collectives.
- Homeostatic Setpointassociated_withLarge-scale organizational target that organisms maintain despite changes to parts; enables flexible achievement through multiple molecular mechanisms.
- Regenerationassociated_withBiological process demonstrating morphogenetic memory and goal-directed anatomical problem-solving; salamanders regrow exact organs and stop when correct structure is complete.
Findings (3)
finding
- Empirical evidence that memories persist through regeneration; challenges substrate-dependence of identity.
- 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.
- Wounds on deer antlers are remembered and reproduced in subsequent years at the same location.supportsDeer farmers observed that a wound on a branched antler results in ectopic tine at that location next year, long after the original antler fell off, indicating spatial pattern memory.
