I assume that [phenomenal] consciousness is a property physical processes can have, and that it involves pre-reflective auto-sensitivity (PRAS), which is related to the much-discussed pre-reflective self-consciousness [3,4]. I then argue that PRAS requires conscious processes to be directly and causally sensitive to their own inner causation as such, and not merely to their own trajectories of physical states as ordinarily understood. That causal sensitivity is therefore metacausation. Metacausation here is where instances of causation are themselves, directly and in their own right, causes or effects. Metacausation (aka higher-order causation) is rarely discussed at all, and has apparently not previously been linked to consciousness. But the proposal is yet more radical as I merely use "causation" to mean microphysical dynamism. I assume (anti-Humeanly) that the universe's law-governed unfolding is a dynamism irreducible to sheer regular patterning over spacetime of familiar physical quantities (masses, charges, fields, curvatures, etc.). Furthermore, I strongly reify dynamism: spatiotemporally specific instances of it are a ``new'' realm of fundamental physical quantities, themselves dynamically interacting in their own right with other quantities (familiar or new). That dynamic interaction is a new level of dynamism, namely metadynamism, with its own laws explicitly mentioning dynamism instances. As causation is just dynamism, metacausation is metadynamism. The poster summarizes the arguments (revising earlier versions [1,2]) and sketches initial formalization steps for metadynamism. It also indicates how metadynamism might be co-opted to enrich other consciousness theories, notably IIT and Orch-OR.

Pedro Mediano - Moving beyond integration and differentiation in measures of neural dynamics
One in a series of talks from the 2019 Models of Consciousness conference. Pedro Mediano
Department of Computing, Imperial College London
In a seminal series of papers, Tononi, Sporns, and Edelman (TSE) introduced the idea that the neural dynamics underlying conscious states are characterised by a balance of integration and differentiation between system components. This idea remains prevalent in consciousness research today, influencing theoretical and experimental work.
Such work has faced a number of challenges. For example, distinct measures designed to measure such a balance behave very differently in practice,
making it hard to choose which is the "right one", and dynamics of conscious and unconscious brains defy some of the predictions of this framework. We argue that these problems arise, at least in part, from the non-specific nature of the concepts of integration and differentiation.
Here, we present a revised mathematical theory of neural complexity: we introduce a new measure, called O-information, that quantifies the balance between redundancy and synergy within a system, and is more effective than TSE’s original measure at describing phenomena where large-scale correlation and short-scale independence coexist; and develop a formalism to decompose different "modes" of information dynamics, providing an exhaustive taxonomy of redundant and synergistic effects. These developments allow us to place previous measures within a common framework and explain their their similarities and differences.
