Our research focus is on the physiological mechanisms underlying the control of masticatory behavior. Our main focus is the study of Bruxism, an involuntary rhythmic or spasmodic non-functional gnashing and grinding of the teeth. Normally, the nervous system must generate precise temporal sequences of muscle contractions when a coordinated movement is produced. These programmed sequences of muscle activity are referred to as "motor patterns", and are produced by rhythmically active networks of nerve cells called "central pattern generators" (CPGs) in the central nervous system. In essence, we are interested in how CPG patterns produced in the brainstem are disrupted by pathology.
