Research Interests
The major interest of our lab is in elucidating the central mechanisms involved in perception of touch, pain and temperature and the pathophysiology of movement disorders.

Most of the studies employ extracellular single unit recordings although some anatomical and psychophysical techniques are also used. Currently most of the projects involve studies on human patients undergoing functional stereotactic surgery for the alleviation of movement disorders or chronic pain. In these studies microelectrode recordings and microstimulation in thalamus, globus pallidus and subthalamic nucleus are performed in awake patients.

The major current studies are examining the
  • Functional characteristics of neurons in motor thalamus, globus pallidus and subthalamic nucleus and the alterations of their responses in various movement disorders sensations
  • Oscillatory activity of neurons and local field potentials in the basal ganglia
  • Mechanisms underlying stimulation produced analgesia
  • Role of thalamus in mediating acute and chronic pain and temperature
  • Mechanisms of sensitization of neurons in rat trigeminal nucleus and thalamus to noxious stimuli
  • Mechanisms of peripheral release of substance P and plasma extravasation


Our lab has strong ties with other researchers at the Toronto Western Research Institute (Chen, Davis, Hutchison, Lang, Lozano, Moro), Department of Physiology (Charlton) and in the Dental School (Sessle, Hu).
