claimQuantum-inspired approaches to consciousness utilize formal features from quantum physics to address psychological phenomena without requiring the full framework of quantum mechanics or quantum field 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.
claimQuantum field theory describes the emergence of classical behavior in brain activity by identifying regimes of stable behavior, such as phases and attractors, and the transitions between them.
claimQuantum field theory allows for a large number of bosons to condense into a highly stable ordered state, providing a derivation of ordered states in many-body systems.
claimUmezawa proposed that dynamically ordered states in quantum field theory represent coherent activity in neuronal assemblies, which is necessary to make encoded content consciously accessible.
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.
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.
claimSpontaneous symmetry breaking in quantum field theory occurs when the ground state (or vacuum state) of a system is not invariant under the full group of transformations providing the conservation laws for the system.
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.
referenceVitiello (2001, 2002) provides nontechnical accounts of the quantum field theory approach to brain states.
claimQuantum field theory deals with systems with infinitely many degrees of freedom, where the algebra of observables admits multiple Hilbert-space representations that are not unitarily equivalent to each other.

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.
claimGeneralized quantum approaches exist that address psychological phenomena using formal features of quantum theory, such as non-commuting operations or non-Boolean logic, without utilizing the full framework of quantum mechanics or quantum field theory.
claimThe approach initiated by Hiroomi Umezawa uses quantum field theory to describe the emergence of classical activity in neuronal assemblies through symmetry breaking, offering a more sophisticated framework than standard quantum mechanics.

claimThe quantum field theory approach to brain modeling avoids the restrictions of standard quantum mechanics in a formally sound way.
claimQuantum field theory yields infinitely many representations of the commutation relations that are inequivalent to the Schrödinger representation of standard quantum mechanics.
referenceRicciardi and Umezawa (1967) proposed using the formalism of quantum field theory to describe brain states, specifically focusing on memory as inequivalent representations of vacuum states in many-particle systems.
referenceThe quantum field theory approach to brain states, originally proposed by Ricciardi and Umezawa, has been refined by researchers including Stuart et al.

claimThe quantum field theory approach to brain modeling contains conceptual ambiguities regarding the distinction between mental and material states.

perspectiveWalter Jackson Freeman and Giuseppe Vitiello envision that mental activity can be explicitly explained within the context of quantum field theory.
claimRicciardi and Umezawa proposed a quantum brain model in 1967 based on the quantum field theory (QFT) of many-body systems to describe the nonlocality of brain functions, specifically memory storing and recalling.
claimIn the 1960s, Luigi M. Ricciardi and Hiroomi Umezawa suggested using the formalism of quantum field theory to describe brain states, with a specific emphasis on memory.

referenceIn quantum field theory, inequivalent representations can be generated by spontaneous symmetry breaking, which occurs when the ground state (or vacuum state) of a system is not invariant under the full group of transformations providing the conservation laws for the system.
claimThe quantum field theory approach to memory posits that memory states are represented as states of many-particle systems, specifically as inequivalent representations of vacuum states of quantum fields.
claimThe term 'quantum cognition' refers to a research area that addresses psychological phenomena using formal features employed in quantum physics without involving the full framework of quantum mechanics or quantum field theory.
