quoteFreeman and Vitiello (2008) clarified that their model "describes the brain, not mental states."
claimThe application of quantum field theory in the Freeman and Vitiello model serves to explain why classical behavior emerges at the level of brain activity.
claimPessa and Vitiello (2003) addressed additional effects of chaos and quantum noise in the context of quantum approaches to consciousness.
claimThe Freeman and Vitiello model identifies regimes of stable behavior, such as phases and attractors, and transitions between them, analogous to classical thermodynamics arising from quantum statistical mechanics.
referenceFamiliar models of neuronal assemblies, such as those reviewed by Anderson and Rosenfeld (1988), are mostly formulated without invoking well-defined elements of quantum theory, with the exception of the approach by Umezawa, Vitiello, and others.
claimDissipation leads to finite lifetimes of vacuum states, representing temporally limited memory, and generates a genuine arrow of time for the system while inducing entanglement with the environment (Alfinito and Vitiello 2000; Alfinito et al. 2001).
claimFreeman and Vitiello (2006, 2008) identified electric and magnetic field amplitudes and neurotransmitter concentrations as potential neurobiologically relevant observables.
referenceVitiello (1995) describes how the interaction of a system with its environment causes a doubling of the collective modes of the system, yielding infinitely many differently coded vacuum states and allowing for many memory contents without overprinting.
referenceThe article 'Quantum Approaches to Consciousness' surveys several quantum-based theories of consciousness, including those proposed by Henry Stapp, Umezawa and Vitiello, Beck and Eccles, Penrose and Hameroff, dual-aspect approaches (Pauli, Jung, Bohm, Hiley), and models characterizing mental features using quantum formal structures (Aerts and colleagues).
quoteFreeman and Vitiello (2008) stated: "neurons, glia cells, and other physiological units are not quantum objects in the many-body model of brain."
referenceThe quantum field theory approach to brain states, originally proposed by Ricciardi and Umezawa, has been refined by researchers including Stuart et al. (1978, 1979) and Jibu and Yasue (1995), with recent progress incorporating effects of dissipation, chaos, and quantum noise by Vitiello (1995) and Pessa and Vitiello (2003).
claimThe Freeman and Vitiello model views brain states as classical states.

claimFreeman and Vitiello (2006, 2008, 2010) studied neurobiologically relevant observables such as electric and magnetic field amplitudes and neurotransmitter concentration to describe brain states.
claimVitiello (2012) posits that the emergence of self-similar, fractal power-law distributions is intimately related to dissipative quantum coherent states.
claimThe approach to modeling neuronal assemblies developed by Umezawa, Vitiello, and others is an exception to standard models because it incorporates quantum theory.
referenceSabbadini and Vitiello (2019) provide a review with technical background on the application of quantum field theory to brain activity.
claimPessa and Vitiello (2003) addressed the effects of chaos and quantum noise within the context of quantum field theory approaches to the brain.
claimVitiello (1995), Pessa and Vitiello (2003), and Vitiello (2012) advanced the quantum field theory approach to brain states by incorporating effects of dissipation, chaos, fractals, and quantum noise.
claimDissipation leads to finite lifetimes of vacuum states, representing temporally limited memory, as demonstrated by Alfinito and Vitiello (2000) and Alfinito et al. (2001).
claimFreeman and Vitiello (2010) and Freeman and Quian Quiroga (2013) found evidence for non-equilibrium analogs of phase transitions and power-law distributions of spectral energy densities of electrocorticograms.
claimFreeman and Vitiello (2008) clarified that the quantum field theory model of the brain describes the brain itself, not mental states, correcting previous confusion between mental and material states.
referenceSabbadini and Vitiello explored entanglement and phase-mediated correlations in quantum field theory as applied to brain-mind states in their 2019 paper published in Applied Sciences.
claimFreeman and Vitiello (2016) proposed a method to explicitly include mental states in their model of brain activity in their final joint paper.
referenceVitiello (2001, 2002) provides nontechnical accounts of the quantum field theory approach to brain states.

claimThe specific mechanism for how resonating structures communicate and achieve shared resonance remains unknown in the theories proposed by Freeman, Vitiello, Hunt, and Schooler.
claimFreeman and Vitiello apply many-body quantum field theory, originally developed in condensed matter physics, to describe long-range coherent brainwaves.
