Epigenetics and Bruxism: from Hyper-Narrative Neural Networks to Hyper-Function

摘要

This article develops a biosemiotic ' hyper-narrative model ' for the purposes of investigating emergent motor behaviors. It proposes to understand such behaviors in terms of the following associations: the organization of information acquired from the environment, focusing on narrative; the organizational dynamics of epigenetic mechanisms that underly the neural processes facilitating the processing of information; and the evolution of emergent motor behaviors that enable the informational acquisition. The article describes and explains these associations as part of a multi-ordered and multi-causal generative principle of biological phenotype emergence that supersedes the theory of the arbitrary coding of life. Preceeding from narrative's operations in a biological dimension, the article presents scientific research dealing with the associations of action-oriented organization of narrative information and underlying psychological and physiological dynamics and depicts the relations with a distributed multi-directional mapping dynamic. The article presents the explanatory implications of such a hyper-narrative dynamic model on an example of emergent motor behaviors - bruxism. Central to this discussion is the exploration of the possible mechanisms of emergence and etiopathogenesis of bruxism, based on its neurobiology. The article takes the perspective that complex systems dynamics themselves with a tendency to narrative form are found not to be underlain merely by arbitrary coded mechanisms but, rather, biological neural networks (e.g. neuro-epigenetic network) that render context-dependent bio-informational mapping analogous to that of the narrative possible.
