Title : Variabilité anatomique du sillon temporal supérieur

Supervisors : Olivier Coulon (groupe MeCA), Pascal Belin (équipe Banco) The goal of this project is to study the anatomical variability of the superior temporal sulcus (STS). The STS is a fold located in the superior part of the temporal lobe. It is one of the main primary sulci and is related to important brain functions such as language, sound perception or social interactions. Nevertheless, it shows a large inter-subject variability. In particular, the number of pieces and their orientations is variable, as well as the number of branches in the posterior part of the sulcus. Few studies have ben published about the morphology of the STS, and the variability of this morphology across the population is still to be understood and related to underlying functions. During this project, the student will itemize the possible anatomical configurations of the STS based on a large database that includes several tens of subjects, and using a software tool that makes the delineation of the STS (or its various pieces) fundus very easy. The work will start with the two papers below.
