-This chapter explores the complex and dynamic nature of the masticatory system through the lens of modern physics and biology, framing it as a "Complex System." Such systems are characterized by their components' interaction and the emergence of behaviors that are not easily predictable through linear analysis. The chapter delves into the theory of "Complex Systems," focusing on holistic investigation methodologies, mathematical modeling, and the concept of self-organization.
+This chapter explores the complex and dynamic nature of the masticatory system through modern physics and biology, framing it as a "Complex System." Such systems are characterized by interactions among components and emergent behaviors that are not easily predictable through linear analysis. The chapter delves into "Complex Systems" theory, focusing on holistic methodologies, mathematical modeling, and self-organization.
-Preliminary Consideration on Connectivity
+The concept of "Connectivity" is introduced as crucial for understanding complex systems across various disciplines, exploring both structural and functional connectivity. This sets the stage for a deeper exploration of the masticatory function, increasingly recognized as a complex system due to its interactions with the central nervous system (CNS) and other distant systems.
-The chapter introduces "Connectivity" as a crucial concept for understanding complex systems across various disciplines. It explores both structural and functional connectivity, emphasizing the challenges of using connectivity to comprehensively understand complex systems. This discussion sets the stage for a deeper exploration of the masticatory function, which is increasingly recognized as a complex system due to its interactions with the central nervous system (CNS) and other distant functional systems.
-Mastication as a Complex System
+Historically viewed as a peripheral function isolated to phonetics and chewing, mastication is redefined as a complex system with broad biological implications. The chapter criticizes reductionist approaches that focus solely on mechanical aspects, advocating for a model that considers the stochastic nature of biological systems where various interactions produce emergent behaviors.

The chapter criticizes reductionist approaches that focus solely on the mechanical aspects of mastication, advocating instead for a model that considers the stochastic nature of biological systems where various interactions produce emergent behaviors.
-Emergent Behavior and Systems Analysis
+Emergent Behavior (EB) in complex systems like mastication arises from component interactions. Understanding these interactions requires an integrated analysis, considering all components in both space and time, contrasting with traditional views that treat the masticatory system merely as mechanical processes.
-Emergent Behavior (EB) in complex systems like mastication arises from the interaction of various system components. The chapter argues that understanding these interactions requires an integrated analysis, considering all constituent components in both space and time. This approach contrasts sharply with traditional views that treat the masticatory system as merely a set of mechanical processes.
-Vestibular and Trigeminal System Interaction
+A study highlighting the interaction between the vestibular and trigeminal systems showcases how acoustic stimuli can evoke electromyographic (EMG) responses in the masseter muscle, illustrating the integrated nature of sensory and motor responses and reinforcing the concept of the masticatory system as part of a broader interconnected system.

This example illustrates the integrated and complex nature of the body's sensory and motor responses, reinforcing the concept of the masticatory system as part of a broader interconnected system.
-Cognitive Processes and Mastication
+The chapter also touches on the relationship between mastication and cognitive processes, with studies using functional MRI (fMRI) and positron emission tomography (PET) showing that mastication can increase cortical blood flow and activate various brain regions, enhancing cognitive performance.

-==Preliminary Consideration ==
 In recent years, parallel developments in different disciplines have focused on what has been called "Connectivity", a concept used to understand and describe the "Complex Systems". The conceptualizations and functionalisations of connectivity have evolved widely within their disciplinary boundaries, but there are clear similarities in this concept and in its application across the disciplines. However, any implementation of the concept of connectivity involves both ontological and epistemological constraints, which lead us to wonder if there is a type or set of connectivity approaches that could be applied to all disciplines. In this review, we explore four ontological and epistemological challenges in using connectivity to understand complex systems from the point of view of very different disciplines.
