- Proteins that set membrane potential; function as transistors with historicity, forming the hardware of bioelectric networks.
- Cellular machinery controlling resting potential and voltage dynamics; manipulable via drugs or optogenetics to modulate morphogenetic outcomes.
- Pharmacological modulation of ion channels (e.g., barium for K+ channels) used to perturb morphogenesis.
- Experimental techniques to alter Vmem and gap junction states, enabling functional studies of bioelectric pattern memory.
- Misexpression of a single ion channel induces complete ectopic eye formation in gut endoderm of vertebrates.finding0.734Setting cells to an eye-like bioelectric prepattern via ion channel manipulation creates fully formed eyes in abnormal locations, where the master gene Pax6 is insufficient.
- Ion channels enable electrical communication in bacterial communities (Prindle et al. 2015)finding0.689Bacteria use similar bioelectric mechanisms to metazoans to coordinate collective behavior.
- Ectopic eyes induced by ion channel misexpression; if few cells injected, they recruit unmanipulated neighbors to produce normal-sized eyes—collective recruitment competency.
