Experimental indications of non-classical brain functions

Recent proposals in quantum gravity have suggested that unknown systems can mediate entanglement between two known systems, if and only the mediator itself is non-classical. This approach may be applicable to brain, where speculations about operations consciousness cognition a long history. Proton spins of bulk water, which most likely interfere with any brain function, act as systems. If an exists, then NMR methods based on multiple coherence (MQC) witness. However, there are doubts today's signals contain correlations general, specifically environment. Here, we used witness protocol zero (ZQC) whereby minimised classical circumvent detection limits for correlation. For short repetitive periods, found evoked parts temporal appearance resembled heartbeat-evoked potentials (HEPs). We those had no correlates contrast. Similar HEPs, signal depended conscious awareness. Consciousness-related or electrophysiological NMR. Remarkably, these appeared local properties magnetisation were reduced. Our findings suggest witnessed mediated by consciousness-related functions. Those functions must operate non-classically, would mean
