Although cortical elements of the limbic system are quite well defined, the underlying white matter pathways are not well detailed. This project aimed to better describe white matter tracts of the limbic system using both fiber dissection, and in and ex vivo Diffusion Weighted Imaging (DWI) techniques. In vivo data (from DWI and neuropsychological evaluations) were obtained from healthy subjects aged 82 and over previously enrolled in the FIBRATLAS project funded by the French Research Agency and run in the host laboratory. Correlations between neuropsychological and white matter characteristics on DWI were examined in this group to infer function of the limbic white matter tracts. Ex vivo data from the FIBRATLAS project database and from the Tours Body Donation Program were examined. The brains were extracted and used to study the anatomy of the limbic white matter tracts employing both DWI and fiber dissection according to a variant of the Klingler’s method.
