| Research Projects Our research focuses on biological mechanisms of voluntary movement. We study the uniquely complex movements of human speech production and build detailed anatomical and physiological models of the underlying neural control. We carry out parallel studies of multi-joint arm movement and likewise develop computer models of arm motor control. The overall goals are to understand the interplay of sensory and motor function in the control of movement and also the relationship between predictive and responsive aspects of motor control. Our current interests are in understanding the somatosensory basis of speech production, the maintenance of stability in orofacial and limb motor behaviours, learning and adaptation in speech and limb movement, and more generally the relationship between neural and biomechanical determinants of movements. Our psychophysical studies involve the use of robotic devices that apply precise mechanical loads to the arms or the jaw. The work also involves 3D motion measurement, electromyographic recording and physiological modeling. For further information or to request reprints of articles please contact David Ostry.
