“…The isolated sections of the brainstem of neonates containing the V, VII and XII motor nuclei are each capable of generating the sucking rhythm when isolated from the other motor nuclei ( Nakamura et al, 2004 ), as are the left and right halves of the trigeminal section ( Tanaka et al, 1999 ). These data suggest that there could be at least six separate rhythm generators (two V, two VII and two XII) that are coupled together to coordinate suckling at birth.…”

Mammals perform a multitude of well-coordinated orofacial behaviors such as breathing, sniffing, chewing, licking, swallowing, vocalizing, and in rodents, whisking. The coordination of these actions must occur without fault to prevent fatal blockages of the airway. Deciphering the neuronal circuitry that controls even a single action requires understanding the integration of sensory feedback and executive commands. A far greater challenge is to understand the coordination of multiple actions. Here we focus on brainstem circuits that drive rhythmic orofacial actions. We discuss three neural computational mechanisms that may enable circuits for different actions to operate without interfering with each other. We conclude with proposed experimental programs for delineating the neural control principles that have evolved to coordinate orofacial behaviors.

“…We now know that the circuits that are essential for rhythmical trigeminal activity lie between the rostral poles of the trigeminal (NVmot) and facial (NVII) motor nuclei [13,14]. There is also some evidence that the rhombomeres containing NVII and NXII can generate rhythmical motor outputs associated with suckling in neonatal animals [14], but we do not know if this ability exists in more mature brains.…”

Mammalian mastication results from the interaction of an intrinsic rhythmical neural pattern and sensory feedback generated by the interaction of the effecter system (muscles, bones, joints, teeth, soft tissues) with food. The main variables that explain variation in the pattern of human mastication are the subjects themselves, their age, the type of food being eaten, and time during a sequence of movements. The intrinsic pattern of mastication is generated by a central pattern generator (CPG) located in the pons and medulla. The output of the CPG is modified by inputs that descend from higher centers of the brain and by feedback from sensory receptors. Intraoral touch receptors, muscle spindles in the jaw-closing muscles, and specialized mechanoreceptors in the periodontal ligament have especially powerful effects on movement parameters.
