Research Interests :
research works focus mainly on sensory substitution.
In the framework of my PhD thesis at the Université Catholique de Louvain,
I investigated the similitude existing between sensory substitution
perception and normal visual perception. My approach consists in applying
behavioural methods and functional brain imaging techniques (PET, fMRI) in
a cognitive perspective. In the behavioural studies, I try to demonstrate
the possibility to perceive pure visual phenomena (e.g. visual illusions,
depth perception from pictorial cues) using a Prosthesis Substituting Vision
with Audition (PSVA). In the neuroimaging studies, I investigate the
neural networks involved in different kind of perception with the PSVA
(e.g. 2-D form recognition, depth perception).
also interested in studying
1) the impact of early sensory deprivation
(mainly visual deprivation) on the cerebral development (cortical
reorganisation related to early brain plasticity),
2) the late brain plasticity related to the acquisition
of new cognitive abilities in early blind subjects and
3) the effect of vision and visual experience on
several cognitive functions (e.g. perception, memory, calculation, etc.).
