Placebo effects of analgesia, and the influence of analgesia (morphine and other opiods on sleep). Orofacial pain and oral medicine.
Methodologies:
Polysomnography, spectral analysis of cardiac variability and cerebral activity, morphology of respiratory waves in relation to oromandibular and nasal structure, and psychophysiological pain evaluations using quatitative methods.

- Research on factors affecting vigilance in patients experiencing chronic pain: assessment with a behaviour simulator and neupsychological tests (Collaboration with Dr Anne Decarie, Departement de psychologie, Universite de Montreal)
- Physiological and pharmacological research on abnormal movements during sleep: bruxism (teeth grinding and clamping), myoclonia, torticollis and periodic limb movements (Collaboration with Dr Jacques Montplaisir, Departement de psychiatrie, and Dr Pierre Blanchet, Faculte de medecine dentaire, Universite de Montreal)
