Resumo(s)
The present work fuses insights from the Integrated Information Theory of Consciousness (IIT), the Communication through Coherence Hypothesis (CTC) and the Critical Brain Hypothesis (CBH) into a coherent understanding of the information dynamics of integrated oscillatory networks. Assuming their proposals to hold, the prediction that positive degrees of consciousness causally affect synchronisation of neural oscillators is tested against computationally modelled data gathered from Neuropercolation Models. An intimate relationship between dynamical susceptibility, oscillatory coherence and causal irreducibility is presented. Confirming the prediction of causal interaction between integrated information and synchronisation, an account of the essential role that falls to consciousness in the efficacious establishment of long-range cortical coherence is offered. The thoughtprovoking contributions of IIT are appreciated with a discussion on its implications for the related disciplines of self-organising systems and critical brain dynamics, its challenges for future consolidation of its formalism into a consistent theory being outlined.
