Gap junction blockade stochastically induces heads of other planarian species in genetically wild-type worms.

Temporary disruption of gap junctions causes planaria to reconstruct heads appropriate to other species, revealing latent morphospace attractors.

concept

Gap Junctions
supports
Cellular connections that enable bioelectric communication; form bioelectric networks underlying morphogenetic control and can be manipulated experimentally via molecular reagents.
Wiping of ownership information by gap junctions
supports
Gap junctional coupling erases origin metadata of signals, causing cells to experience false physiological memories, binding them into a larger Self.
