Consciousness Viewed in the Framework of Brain Phase Space Dynamics, Criticality, and the Renormalization Group

چکیده
To set the stage for viewing Consciousness in terms of brain phase space dynamics and criticality, I will first review currently prominent theoretical conceptualizations and, where appropriate, identify ill‐advised and flawed notions in Theoretical Neuroscience that may impede viewing Consciousness as a phenomenon in Physics. I will furthermore introduce relevant facts that tend not to receive adequate attention in much of the current Consciousness discourse. As a new approach to conceptualizing Consciousness, I propose considering it as a collective achievement of the brain' s complex neural dynamics that is amenable to study in the framework of state space dynamics and criticality. In Physics, concepts of phase space transitions and the Renormalization Group are powerful tools for interpreting phenomena involving many scales of length and time in complex systems. The significance of these concepts lies in their accounting for the emergence of different levels of new collective behaviors in complex systems, each level with its distinct ontology, organization and laws, as a new pattern of reality. The presumption of this proposal is that the subjectivity of Consciousness is the epistemic interpretation of a level of reality that originates in phase transitions of the brain‐body‐environment system. 1. Introduction. The metaphysical tradition, prevailing in the West since the 17th Century, views reality as objective in the sense of being accessible and, in principle, knowable to all observers. The study of mental phenomena such as beliefs, desires, thoughts, hopes, fears and conscious states of subjective experience, generally, conflicts with this position: it excludes the region of reality to which these subjective phenomena belong. Yet, as we know well from personal experience, these phenomena do exist. To accommodate this fact, Searl [122] proposed that the phenomena of subjectivity are realized in the brain as an Ontology to which we have epistemic access in the form of the features of our subjectivity. Expanding on this view, the subjectivity of the Mental is not merely an epistemological fact; rather the epistemic access points towards a (physical) ontology whose intrinsic properties (ontic states) are epistemically accessible as the features of subjectivity (for ontic and epistemic states, see Section 3.3). Thus, the central goal of this essay is to introduce a point of view that the Ontology of the Subjective is constituted within the framework, and under the auspices, of the laws of Physics and Biology. Emphatically, this is not to advocate a "naturalistic dualism" in the manner envisaged, …

Time-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
متن کاملProposed Renormalization Group Analysis of Nonlinear Brain Dynamics at Criticality
Perception is characterized by the formation of spatiotemporal patterns of neural activity that embody mental categories of the material events provided by the senses. The patterns are constructed by modifications of the background activity, which is maintained and self-regulated at criticality, such that all frequencies and wavelengths coexist in neural activity, from the atomic level to the w...
متن کاملOn Neural Substrates of Cognition
Recent experiments with highresolution brain imaging techniques provide an amazing view on the complex spatio-temporal dynamics of cortical processes. There is ample of evidence pointing to frequent transitions between periods of large-scale synchronization and intermittent desynchronization at alpha-theta rates (period length of 0.1 s to 0.25s). These observations have been interpreted based o...

Background and Aim: Traumatic brain injury is one of the leading causes of mortality and disability in young adults. Epigallocatechin-3-gallate, the antioxidant compound of green tea, has been proposed to have antioxidant and anti-inflammatory properties. This study evaluates the potential effects of epigallocatechin-3-gallate on the early clinical outcome and serum S100B levels (biomarker for ...
متن کاملRenormalization of Nonequilibrium Systems with Critical Stationary States.
We introduce the general formulation of a renormalization method suitable to study the critical properties of nonequilibrium systems with steady states: the dynamically driven renormalization group. We renormalize the time evolution operator by computing the rescaled time transition rate between coarse grained states. The obtained renormalization equations are coupled to a stationarity conditio...
