Bioelectricity—the study of electrical signals and gradients in living organisms—has quietly gained ground as one of the most fascinating and potentially game-changing fields in biology and medicine. Professor Michael Levin is at the forefront of this paradigm shift. His research explores how bioelectric fields guide the formation of organisms and potentially offer avenues to combat diseases like cancer or spur regenerative growth, all by “speaking” directly to cells’ collective intelligence.
In this blog post, we will expand on a video interview with Prof. Levin to explore how bioelectric signals function as a “cognitive glue” for our bodies. You will also read about how bioelectricity can transform our understanding of cancer treatment, limb regeneration, and even broader philosophical questions about consciousness and collective intelligences. Below, you will find:

Let’s dive in.
Introduction: Why Bioelectricity Matters
Bioelectricity refers to the electrical potentials and ion flows across cell membranes that, together, form gradients or fields within tissues. Historically, we associate electric signals in the human body with nerve impulses—action potentials traveling along neurons. However, Prof. Michael Levin’s work extends much deeper than classical neuroscience. He believes—and has demonstrated experimentally—that non-neural cells also use bioelectric signals to coordinate higher-level structures.
In other words, cells communicate with each other in ways similar to how neurons communicate in our brains. This offers new insights into how single cells coordinate to build complex organs like hearts, limbs, or entire organisms. If we can learn to manipulate these bioelectric signals (“software”), we might steer cells toward desired outcomes: regenerating tissues, preventing tumors from forming, or even telling cells to create anatomical structures that do not usually form.
Why should we care? Current medicine often focuses on the “hardware” level—targeting individual genes or proteins—to fix medical problems. This approach, while powerful, can be extremely complicated and time-consuming. By shifting our focus to bioelectric states, we might tap into a higher-level control system that orchestrates cellular activities more holistically. The implications, from regenerative medicine to cancer therapy, are enormous.
Bioelectricity as Cognitive Glue
How Cells “Mind-Meld”
One of Levin’s central analogies is that bioelectricity is a cognitive glue—a mechanism that integrates individual cells into a larger, goal-directed collective. He draws a parallel with the human brain: neurons share electrical signals through synapses to become a unified mind. Likewise, non-neural cells can be electrically coupled through gap junctions, channels that allow ions and other small molecules to flow directly from cell to cell.
When cells are connected through these gap junctions, a phenomenon akin to a “mind-meld” can occur. Each cell is no longer an isolated unit. Rather, the boundary between “self” and “external environment” shifts so that the entire network of cells shares certain electrical states. Think of it as multiple individuals pooling their perceptions into one cohesive perspective. This allows for group-level decision-making and memory storage, which is exactly what happens in a complex organ or in embryonic development.
Levin emphasizes that this “mind-meld” can scale upward or downward. A cell that “disconnects” from its neighbors electrically can revert to a more primitive state of self-interest, ignoring the body’s greater purpose. This has critical relevance to cancer, as we’ll see below.
Voltage Gradients and Goal-Directed Development
Beyond simple connectivity, bioelectric signals encode goal states or blueprints for tissues and organs. Levin’s lab uses fluorescent dyes and other molecular sensors to visualize the voltage gradients across cells. In tadpoles or planarian flatworms, these “voltage maps” precede the actual physical formation of limbs, eyes, or neural tissues. They are like the outlines or “electric faces” that appear well before the cells themselves arrange into recognizable structures.
Researchers can manipulate these voltage states to “reset” the goals the tissue is trying to achieve. Strikingly, by changing the bioelectric pattern in certain planarian flatworms, Levin’s group has induced the worms to grow two heads instead of one—and those changes can persist in subsequent regenerations. This doesn’t require altering the DNA (the hardware). Instead, it is a top-down instruction that the collective of cells obeys because they are attuned to shared electrical signals.
Cancer Through a Bioelectric Lens
The Standard (Hardware) Approach vs. the Bioelectric (Software) Approach
Cancer is the second leading cause of death globally, and the primary interventions—chemotherapy, radiation, surgery—are sometimes effective but also come with significant side effects. Traditional oncology mostly sees cancer as a genetic disease: a set of gene mutations that cause uncontrolled cell growth. The approach is: “Find the broken genes, fix or destroy the cells.”
Levin’s perspective redefines the central question about cancer. Instead of seeing tumor cells purely as “broken hardware,” he posits that cancer arises when certain cells electrically disconnect from the body’s bioelectric “mind-meld.” Once these cells lose that connection, they behave like single-celled organisms—focusing on individual survival rather than the collective good. Metastasis, then, can be viewed as these “rebel” cells roaming the body, ignoring the organ-level blueprint.
Forcing Tumor Cells to Rejoin the Collective
In frog models, Levin’s lab has shown a remarkable phenomenon: even if they inject potent oncogenes (genes known to trigger cancer), tumors can be prevented or even reversed by forcing the cells to remain in the correct electrical state. In other words, you do not necessarily have to get rid of the oncogene; you just have to keep the cells connected to the shared bioelectric pattern. If they must remain integrated, they “remember” they are part of a larger organ and stop proliferating recklessly.
This opens up a potentially groundbreaking therapeutic avenue. Instead of trying to kill tumor cells (with all the collateral damage that entails), a clinician might “electrically re-educate” them, much like a teacher guiding a misbehaving student back into the fold. If future research confirms this approach’s viability in humans, we could see a fundamental change in how we treat cancers—potentially with fewer of the toxic side effects associated with existing treatments.
Regenerative Medicine and Morphogenesis
Planaria and Two-Headed Worms
Planarian flatworms are famous for their extreme regenerative abilities. Cut them into hundreds of pieces, and each piece can regenerate into a complete worm. Prof. Levin’s lab has exploited this property to show that specific bioelectric manipulations can “rewire” the planarian’s pattern memory. Worms can be induced to grow two heads, and amazingly, when you cut those new heads off, the worms can regenerate two-headed structures again.
In a conventional, strictly genetic framework, this should not happen unless you’ve altered the worm’s DNA. But the worms remain genetically normal. What changes, Levin argues, is the bioelectric circuit—comparable to flipping a software-level toggle that says, “Grow a second head.” The fact that this persists across multiple rounds of regeneration strongly suggests that tissues can store “pattern memories” outside the genome.
Bioelectric Pre-Patterns: The “Face” Before It Forms
Using fluorescent voltage dyes, Levin’s group can visualize “electric faces” in developing organisms. Before a tadpole’s face actually forms, you can see an electrical pattern that demarcates where the eyes, mouth, and other facial features will appear. Changing these patterns can trigger the formation of additional eyes or other morphological anomalies—without editing the DNA.
Such results highlight that classical genetics is necessary but not sufficient to fully explain morphogenesis (the origin of forms). Genes provide the “hardware” (e.g., the ion channels, receptors, proteins), but the software of bioelectric signals orchestrates how those genes and proteins are deployed in space and time.
The Hardware-Software Analogy in Biology
DNA as Hardware, Bioelectricity as Software
A computer analogy frequently arises in these discussions. We often talk about DNA as if it is the “software” of life. However, Levin suggests flipping that script. In many ways, the genome is more like the hardware—it encodes the proteins and molecular structures that enable cells to do their jobs. By contrast, the “software” is the collective electrical states that can be rewritten without changing the underlying hardware.
Think of it this way: if you want a computer to execute a new program, you do not necessarily have to redesign the CPU or the motherboard (the hardware). You just run a new piece of software. Similarly, if you want cells to form a two-headed worm instead of a one-headed worm, or if you want them to grow an extra eye, you might just change the bioelectric pattern—the top-level instructions that the cells collectively read.
The Limitations of a “Purely Genetic” View
The complexity of living organisms has often led researchers to believe that controlling something like limb regeneration or organ formation requires painstaking micromanagement of every gene or signaling pathway. This is akin to trying to program a complex movement in a robot by specifying the motion of every motor and hinge in excruciating detail.
Yet, the “bioelectric software” approach allows a top-down method. Instead of micromanaging every cell, you present a new “goal state” to the tissue via electrical signals. Then the system’s inherent intelligence does the rest. It is the difference between training a rat to ride a tiny bicycle with treats and punishments, versus trying to mathematically compute which neurons must fire in which sequence to move every muscle. The training method capitalizes on the animal’s built-in capacity for learning; likewise, controlling bioelectric states capitalizes on cells’ built-in capacity to form coherent structures.
Beyond the Genome: Where Are Forms “Stored”?
Latent Space and Evolution’s “Pointers” to Math
One of the most philosophically intriguing aspects of Levin’s work is the question: Where do these patterns come from originally, and how do cells know how to build them? Traditional evolutionary biology suggests natural selection shapes forms over millions of years. Yet even simple systems appear to do things that seem far more sophisticated than random accumulation of mutations.
Levin invokes the idea that evolution often “finds pointers” into a space of possible forms—a “Platonic realm” of mathematics and geometry. For instance, once you have a certain arrangement of ion channels, you might already be able to access entire sets of logic functions (like NAND gates in electronics), which exist in the abstract rules of computation. In that sense, evolution does not have to invent new geometry or new mathematics each time—it just has to discover the physical embodiment (i.e., the hardware configuration) that taps into those preexisting possibilities.
Synthetic Biobots and New Possibilities
Levin’s lab, along with other collaborators, has created “xenobots” and “anthrobots” from frog or human cells, respectively—living cellular aggregates that can move, heal, and even exhibit never-before-seen behaviors like kinematic self-replication. These forms are not coded for by the frog or human genome in the usual sense; they emerge once certain cells are placed in new configurations that expose alternative patterns.
This “latent space” metaphor means there could be many more morphological or behavioral possibilities locked inside our cells than we ever see in standard embryonic development. Like a plant that usually grows a flat green leaf, but under an insect’s influence forms a bizarre, spiky gall, the full repertoire of shapes and tissues might be enormous. By actively tinkering with bioelectric states, scientists might unlock entirely novel forms—offering vast potential in regenerative medicine, synthetic biology, and understanding life’s adaptability.
Consciousness, Intelligence, and the Wider Universe
Could There Be a Planetary Mind?
Levin’s approach to cognition is decidedly unconventional. He frames cognition not as a binary—where brains are conscious but cells (or nonliving systems) are not—but as a spectrum. If cells can exhibit rudimentary memory, decision-making, and goal-directedness, then perhaps these capacities scale up and down. After all, single-celled bacteria can form electrical networks that improve their collective feeding strategy.
This line of reasoning naturally leads to big-picture speculation about a Gaia-like planetary mind. Could the entire planet—its biosphere, geological cycles, weather patterns—form a large-scale intelligence? Levin’s stance is refreshingly empirical: Maybe, but we would need to do experiments to test if such a larger-scale system can learn or exhibit coherent goal-directed behavior. Observing the planet’s processes from the outside might never conclusively reveal if there is “consciousness”; we would need interventions (e.g., attempts to “train” an ecosystem) to see if it can adapt in a goal-directed way.
The Spectrum of Cognition, From Cells to Societies
A key takeaway is that Levin does not pigeonhole cognition into “has or has not.” Instead, cognition is distributed along a continuum. When cells remain electrically connected, they become part of a larger agent whose cognitive light cone—the range of what it can detect, remember, and act upon—expands. Conversely, when cells disconnect (like in cancer), they may devolve into more single-minded, self-serving units.
This scaling can continue. Human neurons form a brain, which in turn forms an individual with complex motivations. Individuals can then form social networks or societies, which may exhibit emergent, group-level intelligence of their own. Whether there is a “topmost” level or if it extends to the entire planet or the universe is an open question—one that challenges both scientific methods and philosophical assumptions.
Practical Implications: Toward a New Ethical and Medical Horizon
- Cancer Treatments
- Instead of destroying tumor cells with harsh treatments, we might be able to “re-educate” them electrically to rejoin the body’s “collective intelligence.” This approach could reduce toxicity and side effects, though it still requires years of research to confirm effectiveness in humans.
- Organ and Limb Regeneration
- Bioelectric manipulation might guide cells to regrow limbs or organs lost due to injury. Salamanders are a natural example of robust regeneration, and Levin’s insights may help us replicate this in mammals. If you can set the correct “target morphology,” cells might do the intricate work of rebuilding on their own.
- Birth Defect Prevention and Correction
- Because bioelectric patterns appear before physical traits, identifying abnormal voltage gradients in early development may allow us to prevent or correct certain birth defects long before they become irreversible.
- Synthetic Biology and Machine Learning
- By treating tissues as “collective intelligences,” we can design living machines (like xenobots) that perform tasks like targeted drug delivery, environmental remediation, or wound healing. These living constructs might be more adaptable than any traditional, mechanical robot.
- Philosophical and Ethical Considerations
- Expanding our concept of “cognition” and “intelligence” beyond nervous systems has ethical ramifications. Are there new boundaries regarding what forms of life or synthetic organisms deserve moral consideration? We already grapple with animal welfare and environmental ethics. Bioelectricity-based intelligence broadens the conversation.
Conclusion: The Road Ahead
Prof. Michael Levin’s work challenges multiple fronts of modern science:
- Medicine and Cancer Research: Shifting from a purely genetic or immunological model of cancer to one where bioelectricity plays a central role could reshape oncology and reduce our reliance on harsh treatments.
- Developmental Biology: The discovery of “electric faces” and the induction of new heads and organs via voltage manipulation demands that we revise our gene-centric view of morphogenesis.
- Philosophy of Mind: By framing cognition as existing on a continuum and relying on shared electrical states, Levin’s view blurs traditional boundaries around conscious minds. Could there be collective intelligences above or below our scale?
- Ethics: Once we accept that even cells have a rudimentary intelligence, our ethical perspective on life—whether it is single cells, synthetic organisms, or vast ecosystems—needs to broaden.
It is too early to say if and when these ideas will revolutionize clinical practice or give us dramatic powers of tissue regeneration. Scientific progress requires replication, refinement, and proof in human models. Yet the horizon looks promising. The potential to “tell” cells to regrow an arm, fix a heart valve, or rejoin the body after becoming cancerous is an astonishing leap from what medicine can accomplish today.
Ultimately, bioelectricity is more than just a novel scientific field—it is also a profound invitation to see life differently. No longer can we think of ourselves as just mechanical or genetic machines with a narrow environment. Instead, each of us is a symphony of cells, integrated into one cohesive whole by shared electrical signals and memories. And if that synergy of mind and body can exist within us, who is to say it does not exist on larger scales?
Michael Levin’s paradigm shift underscores that biology might be about communicating with, rather than commanding, the collective intelligence inherent in living systems. The hope is that by “talking” to cells in their native electrical language, we will open new frontiers in healing, regeneration, and an understanding of consciousness itself.
Final Thought or Call to Action
If you find Levin’s ideas compelling, keep an eye on emerging research in bioelectricity. Consider supporting interdisciplinary labs that combine developmental biology, computer science, and bioengineering. Read widely across fields—philosophy, complex systems, neuroscience—to appreciate the sweeping implications of “goal-directed” tissues. By expanding our scientific understanding of cells as information-processing agents, we also expand our sense of ethical responsibility and creative possibility for our shared future.
