    Research Interests

    Our laboratory focuses on the neurophysiology of the human visual system in individuals with or without neurodevelopment disorders.

    Developmental neurotoxicity

    About one-third of the primate brain is dedicated to visual processing. Thus, the visual system constitutes an excellent target to assess the integrity of cerebral function. In collaboration with Canadian and American researchers, we aim to determine the effects of prenatal exposure to environmental contaminants on the development of sensory systems in an Inuit cohort and in a larger cohort from the Canadian general population.

    Another part of this research topic is the study of the visual neurotoxicity in children exposed to antiepileptic drugs such as Vigabatrin, or following maternal consumption of alcohol during pregnancy.

    Amblyopia and cerebral plasticity

    Under normal viewing conditions, inputs to both eyes are automatically unified by the brain into a single and stable perception. Understanding how the visual system effectively suppresses one scene so that the other can be clearly perceived is crucial not only for visual neuroscience, but could also be beneficial in understanding the physiopathology of human amblyopia. This pathology, leading to an impaired or "lazy" eye, results from a variety of abnormal visual experiences in early life (anisometropia, strabismus, congenital cataract, etc.) and represents an important public health problem affecting 2 to 5% of children. Amblyopia can become even more devastating if the patient looses vision in their good eye. Therefore, the first objective of this research program is to establish a framework that will define the neurophysiological factors required for the emergence of binocular interactions throughout normal development. Using this approach, we aim to understand the neurophysiology of amblyopia, in an effort to provide valuable new insights into the underlying cortical processing dysfunction and ultimately into the treatments of amblyopia.
