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|Software developpment]]). == Deterministic tractography in the central area == {{:members:tristan.moreau:bundle.png|}} == Probabilistic tractography of corpus callosum == {{:members:tristan.moreau:diffusion.png|}} {{:members:tristan.moreau:tracto.png|}} == High-resolution cortical parcellation == {{:members:tristan.moreau:high-resolution.png|}} == Connectivity-based parcellation of SMA/pre-SMA == {{:members:tristan.moreau:ba6.png|}} == Connectivity-based parcellation of Broca areas == {{:members:tristan.moreau:broca_connectivity_based_parcellation.png|}} == Example of a vSparQL query on the reference ontology Foundational Model of Anatomy (FMA)== {{:members:tristan.moreau:vpsarql_query.png|}} ====== Teaching 2013-2014 at université Rennes1 ====== Lectures : 10 hours.
