One in a series of talks from the 2019 Models of Consciousness conference. Camilo Miguel Signorelli Department of Computer Science, University of Oxford Empirical evidence regarding neural studies of consciousness and conscious perception is mainly unknown in fields such as physics and mathematics, or sometimes even misunderstood by many scientists inside the own field of consciousness research. A critical survey of these experiments reveals different aspects and dynamical features among...

One in a series of talks from the 2019 Models of Consciousness conference. Sean Tull Department of Computer Science, University of Oxford Integrated Information Theory (IIT), developed by Giulio Tononi and collaborators, has emerged as one of the leading scientific theories of consciousness. At the heart of IIT is an algorithm which, based on the level of integration of the internal causal relationships of a physical system in a given state, claims to determine the intensity and quality of...

One in a series of talks from the 2019 Models of Consciousness conference. Stuart Hameroff Center for Consciousness Studies, University of Arizona, Tucson, Arizona The Penrose-Hameroff ‘Orchestrated objective reduction’ (‘Orch OR’) theory suggests consciousness arises from ‘orchestrated’ quantum superpositioned oscillations in microtubules inside brain neurons. These evolve to reach threshold for Penrose ‘objective reduction’ (‘OR’) by E=h/t (E is the gravitational self-energy of the...

One in a series of talks from the 2019 Models of Consciousness conference. Sir Roger Penrose Mathematical Institute, University of Oxford A common scientific view is that the actions of a human brain could, in principle, be simulated by appropriate computation, and even that it may not be too far into the future before computers become so powerful that they will be able to exceed the mental capabilities of any human being. However, by using examples from chess and mathematics, I argue, that...

One in a series of talks from the 2019 Models of Consciousness conference. Xerxes Arsiwalla Institute for Bioengineering of Catalonia Barcelona, Spain Theories of consciousness such as Integrated Information Theory (IIT) and its various approximations are grounded on intrinsic information and causal dynamics. However, what seems to be missing or at least is not explicitly addressed in this framework is the role of meaning. One could argue that conscious experience not only generates...

One in a series of talks from the 2019 Models of Consciousness conference. Adam Barrett Sackler Centre for Consciousness Science, University of Sussex, UK Integrated Information Theory (IIT) has gained a lot of attention for potentially explaining, fundamentally, what is the physical substrate of consciousness. The foundational concepts behind IIT were extremely innovative, and it has been very exciting to see certain predictions being upheld in experiments. However, many problems have been...

One in a series of talks from the 2019 Models of Consciousness conference. Johannes Kleiner, Institute for Theoretical Physics, Leibniz University of Hannover. The goal of this talk is to discuss the mathematical basis of models of consciousness, most notably the question of which mathematical structure one is to use to describe experience in any formal theory. This question is inextricably linked with the conceptual basis of models of consciousness. After briefly reviewing the various...
