Abstract
Subdividing the cortex into structural elements, known as parcellation, is a key aspect to apprehend the link between structure and function in the brain. One of the main issue of parcellation is the compilation of the human cerebral connectome and could have important medical applications in medical image as better identify important functional areas to preserve in neurosurgery.
Different aspects of human cerebral structural connectivity were investigated in this thesis using diffusion Magnetic Resonance Imaging (dMRI) and tractography, which is currently the unique technique that could reconstruct structural connectivity in vivo and non invasively.
A first study aimed to characterise short association bundles in the central region using a deterministic tractograhy.
A second study aimed to define a connectivity-based-parcellation using probabilistic tractography.
Finally, the purpose of the last study was to create an applicative ontology in order to produce semantic annotations of connectional fingerprints based on probabilistic tractography.
This thesis gave me the opportunity to develop of a neuroimaging tool box called taopy (cf : Software developpment).
