Just to clarify my position. I am not negating the possible importance of microtubule contributions, oscillations, quantum properties, etc. They are likely important. But, for the narrow question of "what's the origin of bioelectric patterns", none of those are strictly speaking necessary. We need to get past the common claim that "we don't know where they come from" and that some mystery is necessary upstream or else it doesn't work. Mathematical properties of networks involving *only* gated ion channels and gap junctions are sufficient to give interesting self-organizing patterns with all kinds of cool computational properties. Ion channel activity, with nothing else added, in a set of connected cells can set up patterns ab initio from symmetry breaking and amplification. Like Turing Patterns in chemical media: you don't need upstream factors to get interesting bioelectric patterns. Lots of papers showing this on https://t.co/aEc2CYUwyD and by others. But again, that doesn't mean that the real case isn't more complex than this minimal version, and it's entirely likely that other aspects of physics impinge on it in living cells - all these things likely work together. The fields we're looking for are whichever ones give maximal control over the morphogenetic outcome. Whatever is the most tractable control interface. For now, that has been pure bioelectric modification via ion channel targeting - we make eyes, limbs, repair birth defects, normalize tumors, etc. in vivo (in whole-body animal model systems) by managing those. At some point, it may become more tractable to do this via targeting of cytoskeleton or EM dynamics or quantum interfaces. I'm open to all of that!! The more tools the better. But I've not seen any applications where large-scale growth and form in embryogenesis, regeneration, etc. can be controlled that way yet. Hopefully that work expands and offers additional handles on this process; regenerative medicine can use as many different interfaces as we can find.
