Date of birth: August 24th, 1967
2003: Habilitation thesis, University of Caen Basse Normandie
1995: Ph.D. University of Paris VI : Functional anatomy of horizontal saccadic eye movements in healthy human using positron emission tomography.
1991: Prelims in Cognitive Sciences, University of Paris VI.
1990 : Master of Physiology, University of Paris VI
After a Ph.D. in Cognitive Sciences, Laurent Petit made a first post-doctoral fellowship in 1995 in the Laboratory of Neurophysiology (A. Roucoux, Catholic University of Leuven, Belgium) and a second post-doctoral fellow from 1996 to 1998 at NIMH in Bethesda (United States) in the Laboratory of Brain and Cognition (L. Ungerleider).
Recruited at the CNRS in 1998 as a researcher in the Groupe d’Imagerie Neurofonctionnelle (GIN), today integrated in the GIN-UMR5296 in Bordeaux. Specialist in cognitive neuroimaging, his early work concerned the neural basis of eye movements (saccades, pursuit, fixation), and those of attention and spatial working memory. His current research focuses on the identification of factors and biomarkers of human brain structural and functional variability, a project ignited with the 300 subjects BIL&GIN cohort that includes psychometric measurements, anatomical Magnetic Resonance Imaging (aMRI), diffusion tensor Imaging (DTI), neural bases of language and visuo-spatial functions, and functional data in the conscious resting state.
Methodological expertise in magnetic resonance imaging anatomical and functional imaging (aMRI, DTI, fMRI), Positron Emission Tomography (PET), Electro-and magnetoencephalography (MEG-EEG) and video-oculography (measurement of eye movements).
