If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

In this talk we outline an approach to consciousness science that combines insights from Integrated Information Theory (IIT) and the mathematical formalism of Partial Information Decomposition (PID), which we term Integrated Information Decomposition (ΦID). Through this approach, we lay out a formal argument relating consciousness and causal emergence in any given system based on their respective information-theoretic compositions — providing a principled answer to the long-standing dispute on the relationship between consciousness and emergence. Furthermore, leveraging the empirical tractability afforded by ΦID, we build a revised measure of integrated information, ΦR, and argue that a multi-dimensional description of information dynamics based on ΦR and related quantities may provide a principled way to compare the neural basis of different aspects of consciousness. The ‘modes of consciousness’ outlined by ΦID establish a common space for mapping the phenomenology of different conscious states, which as an example we explore through the concept of selfhood. Overall, Integrated Information Decomposition yields rich new ways to explore the relationship between information, consciousness, and emergence in a way that is mathematically rigorous, empirically driven, and ontologically innocent.
