• Using clinical MRI, researchers observed the first indications of a macroscopic quantum entangled state formed by proton spins of water molecules in the living human brain. • By introducing an entanglement witness technique—originally proposed for quantum gravity research—into neuroscience, the team discovered that entanglement signals of proton spins are surprisingly synchronized with Heartbeat-Evoked Potentials (HEPs). • The study provides strong experimental indications that human consciousness, cognition, and brain computational processes are based on non-classical quantum mechanics, confirming that the entanglement-based signals fade away when the subject falls asleep. [Quantum Biology Society] Whether human brain functions, especially consciousness and cognition, are merely the result of classical electrical and chemical signal exchanges between brain cells, or the result of computations akin to a quantum computer based on quantum mechanical principles, has been one of the hottest debates in modern science. While the dominant argument has been that quantum effects would instantly break down in a macroscopic, hot, and wet environment like the brain, a recent study directly capturing strong indications of macroscopic quantum entanglement in the living human brain is exciting the global scientific community. The paper "Experimental indications of non-classical brain functions," published entirely free of charge in the Journal of Physics Communications, contains these remarkable achievements. A research team led by Christian Matthias Kerskens and David López Pérez from the Trinity College Institute of Neuroscience (TCIN) in Dublin, Ireland, successfully conducted this groundbreaking experiment. ■ Quantum Gravity Research Techniques Open the Door to Neuroscience To detect quantum effects in the macroscopic environment of the brain responsible for cognitive functions, the researchers made an unconventional attempt by applying an entanglement witness protocol—originally proposed for quantum gravity research—to clinical magnetic resonance imaging (MRI) of a living human body. MRI measures the proton spins of bulk water in the brain; the researchers highly saturated the magnetization to minimize classical single quantum coherence (SQC) signals, selectively capturing only the target zero quantum coherence (ZQC) signals. ■ Quantum Entanglement in the Brain Synchronized with the Heartbeat The observation results were astonishing. The network of fluid spins (proton spins of bulk water) inside the brain interacted with each other, showing indications of a specific entangled state, and these entanglement-based signal bursts were surprisingly synchronized with the heartbeat-evoked potentials (HEPs) induced by the subject's heartbeat. These pulsating signals could not be explained by any existing classical MRI contrast techniques. ■ Entanglement Signals Disappear as Consciousness Fades Even more interestingly, these quantum entanglement-related signals appeared strongly only when the subjects were in a state of conscious awareness. When the subjects' consciousness faded, such as when falling asleep, the signals invariably and gradually disappeared. This is a strong experimental indication that macroscopic water proton spins related to brain physiology are mediating entanglement through unknown brain functions, further suggesting that the foundation of human brain computational processes and consciousness could be strictly non-classical. This research leaves open the possibility that the human brain operates effectively like a highly complex quantum computer, and it is expected to bring a groundbreaking paradigm shift in neuroscience, psychology, medicine, and the development of next-generation artificial intelligence in the future.
