Before going on to describe the technologies used in the NGF method, we should say something about the foundations on which the scientific philosophy of the method are based. Let's start with the most accurate means of discussing the paradigm, because paradoxically, it changes the interpretation of mastication phenomenon. This new paradigm considers the mastication phenomenon as a complex system that does not work in a linear way, but instead works like stochastic processes. These stochastic processes are nothing more than semi-random processes in which the system can take different routes through to reach the solution. As all these processes cannot be understood, "Emergent Behaviour" we analyse the output data downstream because, as is the case for the "EMG interference pattern" the downstream data corresponds to the sum of all of the system's individual components that come into play, which can render the data unreadable. For this reason, we first of all have to divide the Central Nervous System (CNS) in three virtual levels as shown in the figure, and then interrogate each segment with appropriate external inputs called "Triggers". To achieve this goal, the electromyographs commonly used in dentistry are not suitable, but those used in neurophysiopathology laboratories are. Why not?
