-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 as better identify important fonctional areas to preserve in neurosurgery.
+=== Keywords ===
+Neuroinformatics, IRM, connectome, tractography, connectivity-based parcellation, web semantic, ontology, clustering.
-Different aspects of cerebral **structural connectivity** were investigated in this thesis using **diffusion magnetic resonance imaging** (MRI) and **tractography**.
+== Abstract ==
-  * A first study aimed to characterise short association bundles in the central region based on **diffusion tensor imaging** (DTI).

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.
-  * A second study aimed to use structural connectivity relation to define a **connectivity-based-parcellation** using a **spectral clustering**.
+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]]).
