Profil / Research Interests
A researcher (psychophysicist) and neuropsychologist, Dr Bertone is a cognitive neuroscientist whose principal research interests lie in the assessment of visuo-perceptual and sensorimotor systems in typically and atypically developing populations. His principal publications concern the characterization of neural circuits underlying visual information processing in autism and fragile-x syndrome (FXS). Based on the defining perceptual signatures measured in each condition, he has advanced a causal model that links causal genetic alteration with the neural endophenotypes associated with visual information processing abilities in each condition.
