Résumé
In this study we investigated the effect of medial
temporal lobe epilepsy (MTLE) on the global
characteristics of brain connectivity estimated by
topological measures. We used DSI (Diffusion Spectrum
Imaging) to construct a connectivity matrix where the
nodes represents the anatomical ROIs and the edges are
the connections between any pair of ROIs weighted by the
mean GFA/FA values. A significant difference was found
between the patient group vs control group in
characteristic path length, clustering coefficient and
small-worldness. This suggests that the MTLE network is
less efficient compared to the network of the control
group.
