It is, therefore, essential to switch from a simple and linear model of dental clinic to a Stochastic Complex model of masticatory neurophysiology.

As a confirmation of this more complex and integrated approach to interpret the functions of mastication, a study is presented here where the profile of a "Neural Complex System" emerges. In the mentioned study, the organic and functional connection of the vestibular system with the trigeminal system was analysed. <ref>Deriu F, Ortu E, Capobianco S, Giaconi E, Melis F, Aiello E, Rothwell JC, Tolu E.

As anatomical and physiological studies, both in animals and humans, have shown that masseter muscles are a target for vestibular entrances, the authors of this study have reassessed the vestibular contribution for the masseteric reflexes.

This is a typical example of a base-level complex system as it consists of only two cranial nervous systems but, at the same time, interacting by activating mono- and polysynaptic circuitry (Fig. 1).
