Research is focused on sex differences in stress and emotion regulation in the rat, in the context of the neurobiological basis of anxiety and depression. Studies focus in particular on hemispheric specialization in stress and emotion processing, with emphasis on brain dopamine and serotonin systems. We are also interested in the long-term consequences of early life events on brain function and behaviour. Other areas of interest include the study of paw preference/handedness and its relation to brain and behaviour. An additional line of research involves an animal model of schizophrenia, based on a selective deficit in acetylcholine in the ventral striatum. Techniques used in this lab include behavioural analysis, brain lesioning and microinjections, in vivo recording techniques to measure DA release, neurochemical and neuroendocrine analysis, immunohistochemistry and behavioural pharmacology.
