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.
