In this Opinion article, we discuss how integrated information theory accounts for several aspects of the relationship between consciousness and the brain. Integrated information theory starts from the essential properties of phenomenal experience, from which it derives the requirements for the physical substrate of consciousness. It argues that the physical substrate of consciousness must be a maximum of intrinsic cause–effect power and provides a means to determine, in principle, the quality… Expand

Figures and Topics from this paper

Mechanism Integrated Information
TLDR
It is shown that the new information measure introduced recently captures three postulates of IIT—existence, intrinsicality and information—and is unique, and also satisfies the remaining postulates—integration and exclusion—and creates the framework that identifies maximally irreducible mechanisms. Expand
Predictive processing as an empirical theory for consciousness science
TLDR
It is proposed that progress in consciousness science will best be achieved by elaborating systematic mappings between physical and biological mechanisms, and the functional and phenomenological properties of consciousness. Expand
What Is Consciousness? Integrated Information vs. Inference
  • J. Cooke
  • Computer Science, Medicine
  • Entropy
  • 2021
TLDR
The proposal of consciousness as inference overcomes the shortcomings of Integrated Information Theory, particularly in the case of conscious perception. Expand
What it is like to be a bit: an integrated information decomposition account of emergent mental phenomena
Abstract A central question in neuroscience concerns the relationship between consciousness and its physical substrate. Here, we argue that a richer characterization of consciousness can be obtainedExpand
What Might Interoceptive Inference Reveal about Consciousness?
The mainstream science of consciousness offers a few predominate views of how the brain gives rise to awareness. Chief among these are the Higher-Order Thought Theory, Global Neuronal WorkspaceExpand
Making Sense of Consciousness as Integrated Information: Evolution and Issues of Integrated Information Theory
The purpose of this article is to provide an overall critical appraisal of Integrated Information Theory (IIT) of consciousness. We explore how it has evolved and what problems are involved in theExpand
A Traditional Scientific Perspective on the Integrated Information Theory of Consciousness
TLDR
This paper assesses two different theories for explaining consciousness, focusing on Integrated Information Theory (IIT), which says that consciousness is integrated information (as ϕMax) and says even simple systems with interacting parts possess some consciousness. Expand
The Interstitial Pathways as the Substrate of Consciousness: A New Synthesis
This paper considers three classes of analyses of the nature of consciousness: abstract theories of the functional organization of consciousness, and concrete proposals as to the neural substrate ofExpand
The Limits to Machine Consciousness
  • S. Kak
  • Psychology, Computer Science
  • Journal of Artificial Intelligence and Consciousness
  • 2021
TLDR
It is argued that consciousness is more than an epiphenomenon and assuming it to be a separate category is consistent with both quantum mechanics and cognitive science. Expand
Ten Testable Properties of Consciousness
  • C. Tyler
  • Medicine, Psychology
  • Frontiers in Psychology
  • 2020
This article develops a view of consciousness in the context of a new philosophical approach that invokes the concept of emergence, through which the operative principles of each level ofExpand

Contentless Consciousness and Information-Processing Theories of Mind
Functionalist theories of mind sometimes have viewed consciousness as emerging simply from the computational activity of extremely complex information-processing systems. Empirical evidence suggestsExpand
From the Phenomenology to the Mechanisms of Consciousness: Integrated Information Theory 3.0
TLDR
Integrated Information Theory of consciousness 3.0 is presented, which incorporates several advances over previous formulations and arrives at an identity: an experience is a maximally irreducible conceptual structure (MICS, a constellation of concepts in qualia space), and the set of elements that generates it constitutes a complex.

An information integration theory of consciousness
  • G. Tononi
  • Psychology, Medicine
  • BMC Neuroscience
  • 2004
TLDR
The information integration theory accounts, in a principled manner, for several neurobiological observations concerning consciousness, including the association of consciousness with certain neural systems rather than with others; the fact that neural processes underlying consciousness can influence or be influenced by neural processes that remain unconscious; the reduction of consciousness during dreamless sleep and generalized seizures. Expand
Consciousness as Integrated Information: a Provisional Manifesto
  • G. Tononi
  • Biology, Medicine
  • The Biological Bulletin
  • 2008
The integrated information theory (IIT) starts from phenomenology and makes use of thought experiments to claim that consciousness is integrated information. Specifically: (i) the quantity ofExpand
Consciousness cannot be separated from function
TLDR
It is argued that any neurobiological theory based on an experience/function division cannot be empirically confirmed or falsified and is thus outside the scope of science and a 'perfect experiment' illustrates this point. Expand
How rich is consciousness? The partial awareness hypothesis
TLDR
It is argued that the empirical evidence for phenomenal consciousness without access is equivocal, resulting either from a confusion between phenomenal and unconscious contents, or from an impression of phenomenally rich experiences arising from illusory contents. Expand
Integrated information theory of consciousness: an updated account.
  • G. Tononi
  • Psychology, Medicine
  • Archives italiennes de biologie
  • 2012
TLDR
An updated account of integrated information theory of consciousness (IIT) is presented and some theoretical considerations about the relationship between information and causation and about the relational structure of concepts within a quale are presented. Expand
Integrated information theory of consciousness: an updated account.
  • G. Tononi
  • Medicine
  • Archives italiennes de biologie
  • 2012
TLDR
How liT accounts for empirical findings about the neural substrate of consciousness, and how various aspects of phenomenology may in principle be addressed in terms of the geometry of information integration are summarized. Expand
Measuring Integrated Information from the Decoding Perspective
TLDR
The novel practical measure Φ* is derived by introducing a concept of mismatched decoding developed from information theory that is properly bounded from below and above, as required, as a measure of integrated information. Expand
Information integration without awareness
TLDR
This work suggests that consciousness holds an enabling role in establishing integrative mechanisms that can later operate unconsciously, and in allowing wider-range integration, over bigger semantic, spatiotemporal, and sensory integration windows. Expand
