Abstract
The entanglement phenomenon plays a central role in quantum optics and in basic aspects of quantum mechanics and quantum field theory. We review the dissipative quantum model of brain and the role of the entanglement in the brain-mind activity correlation and in the formation of assemblies of coherently-oscillating neurons, which are observed to appear in different regions of the cortex by use of EEG, ECoG, fNMR, and other observational methods in neuroscience.
Highlights
We review the general features of the dissipative quantum model of brain and the role played by entanglement and quantum field theory (QFT) phase correlations in modeling brain functional activity
The theoretical and experimental successful developments were due in a substantial way to the structure of QFT, which is characterized by the existence of infinitely many unitarily inequivalent representations of the canonical commutation relations (CCR) [3,4]
These representations describe physically different state spaces or phases of the system, and their existence allows the possibility of the spontaneous breakdown of symmetry, which in turn implies the dynamical formation of long-range correlations [5,6,7,8]
Summary
We review the general features of the dissipative quantum model of brain and the role played by entanglement and quantum field theory (QFT) phase correlations in modeling brain functional activity. That such a network of anatomical neuronal links appears to be not fully responsible for the observed patterns of neuronal oscillation, which seem to be generated instead by some other “sort” of nervous organization, by “simultaneous, cooperative activity of millions of neurons spread throughout expanses of the cortex”, in Freeman’s words [14] Cutting or damaging those anatomical links, “higher and higher degree of malfunctioning should be observed” [1], which is not commonly observed: “Bioelectrical waves in the brain can be stopped by treatment with cold, electric shock, or drugs, without loss of memory after recovery, and memory is not lost after many ablation experiments or when a brain is sliced in many directions so that certainly some pre-existent networks are destroyed. The formalism presented in Appendix A makes explicit the mentioned difference between the QFT analysis and other preceding studies
