Kerskens and López Pérez adapted a method from quantum gravity experiments to investigate brain functions, hypothesizing that if known quantum systems (proton spins of 'brain water') interact with an unknown system and entanglement occurs, the unknown system must also be quantum in nature12. Using advanced Magnetic Resonance Imaging (MRI) techniques, they detected signals resembling heartbeat-evoked potentials (HEPs), which are typically not observable through conventional MRI methods34. These signals correlated with conscious awareness and short-term memory performance, suggesting that certain cognitive processes may operate through quantum mechanisms56.

The study's findings suggest a potential link between quantum entanglement and consciousness-related brain functions. Researchers observed that zero quantum coherence (ZQC) signals, designed to minimize classical signals and enhance detection of quantum correlations, appeared only under specific conditions related to conscious awareness.12 This observation supports the hypothesis that certain cognitive processes may be fundamentally non-classical, challenging traditional views of brain function based solely on classical physics. The researchers propose that consciousness itself might mediate entanglement in the brain, opening up new avenues for understanding the nature of human cognition and awareness.34

The researchers employed advanced Magnetic Resonance Imaging (MRI) techniques to detect signals that conventional MRI methods typically cannot observe12. A key component of their methodology was the use of a witness protocol based on zero quantum coherence (ZQC), which was designed to minimize classical signals and enhance the detection of potential quantum correlations2. This innovative approach allowed the team to identify signals resembling heartbeat-evoked potentials (HEPs) in most parts of the brain13. The temporal appearance of these signals was particularly noteworthy, as they correlated with conscious awareness and short-term memory performance, providing further evidence for the potential role of quantum processes in cognitive functions23.

The potential discovery of quantum processes in brain functions could revolutionize our understanding of consciousness and cognitive performance. If confirmed, these findings may explain the brain's ability to outperform supercomputers in tasks involving unforeseen circumstances or novel learning scenarios12. The implications extend beyond neuroscience, potentially influencing the development of advanced quantum computers and bridging the gap between neuroscience and quantum computing2. This research opens up exciting avenues for exploring the intersection of these fields, suggesting that future studies of brain functions may need to incorporate principles from both neuroscience and quantum mechanics to fully grasp the complexities of human cognition3.
