VII. Our Earthuman Ascent: A Major Evolutionary Transition in Individuality
4. Conscious Integrated Information Knowledge
Kim, Hyoungkyu and UnCheol Lee. Criticality as a Determinant of Integrated Information in Human Brain Networks. Entropy. 21/10, 2019. As this well quantified perception of a deep, evolutionary relation between sentient awareness and knowledge content grows in validity and employ, University of Michigan Medical School, Center for Consciousness Science researchers advise that a further feature seems to be an optimum state of critical poise between a more or less orderly condition. As being found everywhere from quantum physical bases to natural and social phases (see Critical Complementarity) cerebral phenomena likewise proceed to fine tune themselves in this way. A concurrent, independent paper Emergence of Integrated Information, Complexity, and Consciousness at Criticality (Sina Khajehabdollahi, herein) comes to the same finding.
Integrated information theory (IIT) describes consciousness as integrated across differentiated knowledgeable systems. However, in a complex dynamic brain, the optimal conditions for integrating information have not been elucidated. In this study, we propose that network criticality, a balanced state between a large variation in functional configuration and a large constraint on structural configuration, may be the basis of the emergence of an integrated information. We tested these hypotheses with a whole brain network model and high-density electroencephalography (EEG) during various levels of human consciousness under general anesthesia. The EEG study demonstrated an explicit relationship between criticality, and level of consciousness. (Abstract excerpt)

As another example of how these malleable IIT insights have gained much employ, University of Munich and Oxford University postdoc computational scholars scope out a generalization so as to give it even broader veracity.

Integrated Information Theory is one of the leading models of consciousness. It aims to describe both the quality and quantity of the conscious experience of a physical system, such as the brain, in a particular state. In this contribution, we propound the mathematical structure of the theory, separating the essentials from auxiliary formal tools. We provide a definition of a generalized IIT which has IIT 3.0 of Tononi et al, as well as the Quantum IIT introduced by Zanardi et. al. as special cases. This provides an axiomatic definition of the theory which may serve as the starting point for future investigations and as an introduction for new researchers. (Abstract)
Koch, Christof. The Feeling of Life Itself. Cambridge: MIT Press, 2019. The veteran neuroscientist (search) is now is President and Chief Scientist of the Allen Institute for Brain Science in Seattle. A decade after his Consciousness book, this edition continues to affirm that a form of sentient awareness pervades and vivifies human and animal realms and much beyond. But any purely computational basis or machine-like embodiment is ruled out. In collaborator with Giulio Tononi (search), the core theme is an exposition of his popular Integrated Information Theory (IIT), which as the section reports, traces a parallel path of personal awareness and complex knowledge. (This 2010s version is a quite fulfills Pierre Teilhard’s 1930s evolutionary pairing of complexity and consciousness, whom Koch lauds in his earlier work.) The Global Neuronal Workspace model is then reviewed along with double detail and image hemispheres, which altogether seem to infer a waxing worldwide Uber-Mind. In closing, Koch notes that this tandem ascent well recovers a 21st century scala naturae, once again from deep substance to human acumen.
Koch, Christoph and Florian Mormann. The Neurobiology of Consciousness. Zewail, Ahmed, ed. Physical Biology: From Atoms to Medicine. London: Imperial College Press, 2008. In an affirmation of David Chalmers’ contention, Caltech neuroscientists affirm that sentient awareness is most characterized and distinguished by its informational content. See also Giulio Tononi herein.
The most promising candidate for such a theoretical framework is the information integration theory of consciousness. It posits that the most property of consciousness is that it is extraordinarily informative. (392) Based on these and other considerations, the theory claims that a physical system can generate consciousness to the extent that it can integrate information. (392)
Kriegel, Uriah and Kenneth Williford, eds. Self-Representational Approaches to Consciousness. Cambridge: MIT Press, 2006. Forthcoming in May, this work will argue that consciousness always involves some form of self-awareness, which is said to go beyond and improve on reductive theories. Check the publisher’s website.
Kriegeskorte, Nikolaus and Jorn Diedrichsen. Peeling the Onion of Brain Representations. Annual Review of Neuroscience. 42/407, 2019. Columbia University and Western University, Ontario neurotheorists open by noting that the brain’s capability to compose, retain and refer to cognitive remembrances of external phenomena has long been debated. The issue is here cast in favor of informational memories via a nested, layered model. The chapter closes with a caveat that brains are not conventional computers. While they do contain stored content, some dynamic (enactive) system may yet be in effect.
The brain's function is to enable adaptive behavior in the world by processing information. The concept of representation links the information processed by the brain back to the world. Although disputed, making the connection between brain activity and what it represents requires knowing which aspects of brain activity matter, how the code works, and how it computes adaptive behavior. In this review, we argue that representation provides a useful link between dynamics and function and suggest which aspects of brain activity should be analyzed to achieve a representational understanding. We peel the onion of brain representations in search of layers (aspects of brain activity) that are involved in computation. (Abstract excerpt)
Lagercrantz, Hugo and Jean-Pierre Changeux. On the Emergence of Consciousness. Lagercratnz, Hugo, et al, eds. The Newborn Brain: Neuroscience and Clinical Applications. Cambridge: Cambridge University Press, 2010. Lagercrantz is professor of pediatrics and neonatology at Karolinska Institute, Stockholm, and Changeux, an Institut Pasteur, Paris, neuroscientist. In this especial volume, these leading researchers, aided by the global workspace model of Bernard Baars and Stanislas Dehaene, can trace a nested, ascendant scale of sentience across a life span from its fetal phase before birth through younger years and onto adulthood. The quickening fetus is newly realized to be in a state as if asleep, but also with an REM dreaming mode (see Schwab, Karin, et al Chaos 19/015111, 2009). An early formative factor are episodic cerebral “waves” that produce millions of new neurons. See also by the authors “The Emergence of Human Consciousness: From Fetal to Neonatal Life” in Pediatric Research (65/3, 2009). But a profound extrapolation might then accrue from these studies. The process of human birth, in which the fetus takes an active role, is stated to be a similar transition as awakening from sleep. Might our imminent EarthKinder “nativity singularity” be seen and facilitated by an intentional attempt to individually and collectively awaken and come to a palliative vision and senses?
The First Awakening. Upon delivery, the newborn baby, who has taken an active part in the process, wakes up for the next few hours. The eyes are wide open with usually large pupils and it may cry. After a couple of hours it usually falls asleep again being awake the following days for only short periods of time, i.e., from 7% to 10% of the circadian cycle. The delivery from the mother’s womb thus would cause a first awakening of the infant from a “resting” or sleeping state in utero. (387)
Lombardi, Olimpia and Cristian Lopez. What Does “Information” Mean in Integrated Information Theory? Entropy. 201/12, 2018. As a current example of how this ITT model is gaining wide avail, University of Buenos Aires and University of Lausanne quantum physicists (search each) propose ways to finesse and include this vital instructional complement of aware knowing consciousness.
Integrated Information Theory (IIT) intends to provide a principled theoretical approach able to characterize consciousness both quantitatively and qualitatively. By starting off with the fundamental properties of experience itself, IIT develops a framework that relates those properties to the physical substratum of consciousness. One of the central features is the role that information plays. In this paper, we will conceptually analyze the notion of information underlying ITT. We argue that information should be understood in the light of a causal-manipulabilist view, such that information must be involved in causal links in order to be precisely defined. (Abstract edits)

An introduction to a commemoration of the 100th anniversary of the publication of Texture of the Nervous System of Man and the Vertebrates by the Spanish neuroscientist Santiago Ramon y Cajal which established modern brain research. As Marijuan surveys the conference papers what is evident circa 1999 is a gradated evolutionary enhancement of cerebral structure and capacity with an attendant increase in self-awareness or consciousness. This proceeds by an iterative “complex adaptive system.”
Mashour, George, et al. Conscious Processing and the Global Neuronal Workspace Hypothesis. Neuron. 105/5, 2020. This is a latest update by American, Dutch, and French neuroscientists including Jean-Pierre Changeux and Stanislas Dehaene on this school of thought, actually, whence local brain areas such as evaluative systems, long-term memory, perceptual systems, motor actions, and attention gather together in a common place from which knowing, responsive awareness can then arise. The paper compares this approach with Integrated Information Theory (see herein) and other ideas. A well-funded program to study both main views Neuroscience Readies for a Showdown Over Consciousness Ideas by Philip Ball in Quanta (March 6, 2019). As one may consider, it will not be either/or but a meld with each group bringing vital features to join in synthesis. In any event, these insightful methods assume a conscious ecomsos, as Christoph Koch avers, which seems made and meant to ascend into our creative sentience.
We review the central tenets and neuroanatomical basis of the global neuronal workspace (GNW) hypothesis, which attempts to account for the main scientific observations regarding the elementary mechanisms of conscious processing in the human brain. The GNW hypothesis proposes that, in the conscious state, a non-linear network ignition associated with recurrent processing amplifies and sustains a neural representation, allowing the corresponding information to be globally accessed by local processors. We examine this hypothesis in light of recent data that contrast brain activity evoked by either conscious or non-conscious contents, as well as during conscious or non-conscious states, particularly general anesthesia. We also discuss the relationship between the intertwined concepts of conscious processing, attention, and working memory. (Abstract)

The University of Toronto and University of Paris neuroscientist team of Mateos, Richard Wennberg, Ramon Guevara and Jose Perez Valazquez (search each) continue their insightful project to quantify and quality how our day and night sentience and somnolence can indeed be traced to neural attributes for this purpose.
We seek general principles of the structure of the cellular collective activity associated with conscious awareness. Analysing brain recordings in conscious and unconscious states, we followed initially the classic approach in physics when it comes to understanding collective behaviours of systems composed of a myriad of units: the assessment of the number of possible configurations (microstates) that the system can adopt, for which we use a global entropic measure associated with the number of connected brain regions. Having found maximal entropy in conscious states, we then inspected the microscopic nature of the configurations of connections using an adequate complexity measure, and found higher complexity in states characterised not only by conscious awareness but also by subconscious cognitive processing, such as sleep stages. Our observations indicate that conscious awareness is associated with maximal global (macroscopic) entropy while the microscopic view captures the high complexity in physiological unconscious states (sleep) where there is information processing. As such, our results support the global nature of conscious awareness, as advocated by several theories of cognition. (Abstract)
