  • Title: Face sensorimotor cortex and its neuroplasticity related to orofacial sensorimotor functions.
    Author: Avivi-Arber L, Martin R, Lee JC, Sessle BJ.
    Journal: Arch Oral Biol; 2011 Dec; 56(12):1440-65. PubMed ID: 21550585.
    Abstract:
    This review describes evidence in subprimates and primates that the face primary somatosensory cortex (face SI) and primary motor cortex (face MI) are involved in sensorimotor integration and control of orofacial motor functions that include semiautomatic movements (e.g., chewing, swallowing) and voluntary movements (e.g., jaw-opening). The review also notes that the neuroplastic capabilities of the face SI and face MI have recently been documented, and may reflect or allow for functional adaptation (or maladaptation) of the orofacial sensorimotor system to an altered oral state or oral motor behaviour. They may contribute to the processes whereby patients undergoing oral rehabilitation can (or cannot) restore the lost orofacial sensorimotor functions. Such understanding is important since pain, injuries to the oral tissues, and alterations to the dental occlusion induced by tooth loss or attrition are common occurrences in humans that may sometimes be accompanied by impaired oral sensorimotor functions. Furthermore, impaired oral sensorimotor functions are common in many neurological disorders, sometimes making the most vital functions of eating, swallowing and speaking difficult and thereby reducing the patient's quality of life. It has also been well documented that such negative consequences can be improved following oral rehabilitation as patients adapt, for example, to a new dental prosthesis aimed at restoring function. Therefore, understanding the mechanisms and cortical neuroplastic processes underlying orofacial sensorimotor functions and adaptation is also important for the development of new therapeutic strategies to facilitate recovery of patients suffering from orofacial pain and sensorimotor disorders and improve their quality of life.
