- | 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. | + | == Abstract == |

- | * A first study aimed to characterise short association bundles in the central region based on **diffusion tensor imaging** (DTI). | + | 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 second study aimed to use structural connectivity relation to define a **connectivity-based-parcellation** using a **spectral clustering**. | + | |

+ | * 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**. | * 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**. | ||
