A 159-step auditable open-quantum-system chain links cerebral metabolism to a coherence-protected information channel in the myelinated axon at 310 K (V148)

For decades, the human brain has been understood primarily as a biological machine powered by chemical reactions. Neurons fire, sending electrical signals along insulated wires called axons to communicate thoughts, sensations, and commands. The insulation, a fatty layer known as myelin, acts like the plastic coating on an electrical cable, ensuring these signals travel fast and do not leak. However, a newer and more controversial idea has begun to take shape: that this biological insulation might do more than just guide electricity. Some researchers now suggest that myelin could also act as a waveguide for light and other forms of radiation, potentially allowing the brain to process information in ways that go beyond simple chemistry. This raises a difficult question for physics: can the warm, wet, and chaotic environment of a living brain sustain the delicate, synchronized states required for such advanced processing? In the world of quantum physics, these synchronized states are incredibly fragile and usually collapse instantly when exposed to heat, a problem known as decoherence.

A new study by independent researcher Alfonso Mendoza Orellana tackles this question directly, proposing a detailed, step-by-step model of how a single segment of a myelinated nerve fiber might function as a protected information channel at body temperature. The research does not claim to have built a physical device or measured these effects in a living human yet; instead, it constructs a massive, transparent simulation consisting of 159 distinct logical steps. This chain of calculations links the energy produced by the brain's metabolism to the behavior of ultra-weak light particles, or photons, and sound-like vibrations, known as phonons, within the nerve's structure. The goal was to see if, under specific physical conditions, these components could work together to transfer information with near-perfect accuracy without relying on the most famous and difficult quantum phenomenon: entanglement, where two particles become inextricably linked across space.

The model begins with the energy source. The brain consumes oxygen and glucose to generate power, and the study calculates that a typical amount of brain tissue produces enough energy to support a tiny but steady stream of light emission. This light, which is naturally emitted by biological tissues, enters a microscopic cavity formed by the layers of the myelin sheath. The researchers describe this space as a Casimir cavity, a confined gap where the rules of quantum mechanics create a specific pressure that helps organize the environment. Inside this cavity, the light interacts with vibrations in the structure. The study simulates how these light particles and sound vibrations convert into one another, a process that happens with high efficiency. Crucially, the model shows that this conversion is not random; it is tightly controlled by the surrounding water molecules, which the researchers suggest can form ordered, coherent domains that act as a stable medium for the information to travel through.

As the simulation progresses through its 159 steps, it introduces a series of checks and balances designed to protect the information. The model includes a mechanism that acts like a filter, ensuring that only signals with the correct timing and phase are allowed to pass. This filtering process is described as a phase-locking dial, which keeps the system synchronized. The information then moves through a final stage designed to transfer the state of the system perfectly from one end of the nerve segment to the other. In the results of this simulation, the system achieves a global efficiency of nearly 97 percent, meaning that almost all the information put into the channel arrives at the other end intact. The study reports that the system can hold a vast amount of data, estimated at four trillion bits, and can fill a billion bits of this capacity in just over nine milliseconds.

A key finding of this work is what the system does not rely on. While many theories about quantum biology focus on entanglement, this simulation explicitly shows that the system functions without it. Instead, the researchers found that the resource driving the process is phase coherence, a state where the waves of light and sound move in perfect unison. The simulation indicates that the connection between the light and the water molecules is so weak in terms of entanglement that it is effectively zero, yet the information transfer remains robust. This suggests that the brain might use a different, perhaps more practical, quantum mechanism to process information than previously thought. The study also rules out the idea that this process requires the brain to be cold or isolated; the entire chain operates successfully at 310.15 Kelvin, which is the standard temperature of the human body.

The researchers are careful to frame these results as a theoretical proof of concept rather than a confirmed biological fact. The numbers and outcomes presented are the result of a computer simulation that strictly follows the laws of physics as currently understood, specifically using equations that describe how open systems interact with their environment. The model is designed to be fully auditable, with every constant, formula, and value logged in a public database for others to inspect and test. The study concludes that it is physically possible for a myelinated axon to operate as a thermodynamically funded information channel at body temperature, provided the specific conditions of the model are met. To move from a simulation to a confirmed reality, the author proposes several testable predictions, such as looking for specific patterns in brain waves in healthy people versus those with early-stage multiple sclerosis, where the myelin sheath is damaged. If these patterns appear or disappear as the model predicts, it would provide strong evidence that this complex, quantum-inspired mechanism is indeed at work in the living human brain.
