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 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.

This presentation will discuss the physical and computational substrates of consciousness as suggested by Integrated World Modeling Theory (IWMT). I will first review how neural synchrony may entail marginalization over Bayesian networks, implementing the implicit calculations of joint beliefs and establishment of marginal message-passing regimes within a predictive processing context. I will describe how association cortices may correspond to shared latent (work)spaces within an autoencoding framework, potentially structured according to principles of geometric deep learning. Along these lines, I will further describe how Scott Aaronson’s “expander graph” critique of Integrated Information Theory may actually provide surprisingly strong support for the use of Phi in identifying necessary (but not sufficient) conditions for realizing potentially conscious systems. I will then discuss how IWMT’s original proposal of the realization of consciousness via alpha-synchronized subnetworks may have contained an error, with subjective experience potentially entailed by beta-complexes generating inferences at faster speeds with more restricted scopes. Finally, time permitting, I will present a model of how pleasure and pain may correspond to conflicting predictions within these subnetworks, potentially suggesting mechanisms by which such processes could be modified with relatively low-tech interventions.
