Findings (4)

Bacterial biofilms exhibit bioelectrically-coordinated oscillatory growth patterns, with a negative feedback loop similar to the vertebrate segmentation clock (Liu et al. 2015, Chou et al. 2022)Shows that collective physiological oscillations in bacterial communities resemble mechanisms in animal development.
Bacterial biofilms use membrane potential dynamics to organize metabolism and memory across communities.Prokaryotes exhibit bioelectric signaling for proliferation control and spatial integration, analogous to pre-neural patterning in animals.
Ion channels enable electrical communication in bacterial communities (Prindle et al. 2015)Bacteria use similar bioelectric mechanisms to metazoans to coordinate collective behavior.
Membrane voltage acts as a coarse-grained parameter subsuming many ion channel combinations.Cells generalize over ion channel microstates via macrovariable Vmem, enabling repurposing of responses for novel stimuli.
