Decrease and recovery of integrated information Φ during anesthesia and sleep on human functional magnetic resonance imaging.

Neuroscience of Consciousness 2025 Keiichi Onoda, Satoru Miyauchi, Shigeyuki Kan et al.

Integrated information theory (IIT) offers an axiomatic framework based on phenomenological properties, allowing the quantification and characterization of consciousness through a measure known as Φ. According to IIT, Φ reflects the level of consciousness and is expected to decrease with loss of consciousness, although empirical data supporting this claim remain limited. In this study, we...

Exploring complex and integrated information during sleep.

Neuroscience of Consciousness 2024 Keiichi Onoda, Hiroyuki Akama 2 citations

The Integrated Information Theory is a theoretical framework that aims to elucidate the nature of consciousness by postulating that it emerges from the integration of information within a system, and that the degree of consciousness depends on the extent of information integration within the system. When consciousness is lost, the core complex of consciousness proposed by the Integrated...

Complex of global functional network as the core of consciousness.

Neuroscience Research May 1, 2023 Keiichi Onoda, Hiroyuki Akama

Finding the neural basis of consciousness is challenging, and the distribution location of the core of consciousness remains inconclusive. Integrated information theory (IIT) argues that the posterior part of the brain is the hot zone of consciousness, especially phenological consciousness. The IIT has proposed a "main complex", a set of elements determined such that the information loss in a...

Collapse of local circuit integrated information Φ during NREM sleep

Keiichi Onoda

Abstract Clarifying the mechanisms underlying the emergence of consciousness remains a fundamental challenge in modern neuroscience. Integrated Information Theory (IIT) provides a mathematical framework derived from the phenomenological properties of consciousness as its axioms. IIT proposes that consciousness is identical to a system’s intrinsic cause-effect information structure, quantified...
