Overlap Between Stuttering and Language Networks

We investigated the correspondence between the stuttering-related cortical network with other language-related networks (Sepulcre, 2015). Particularly, we spatially compared the topological distribution of the connectivity map obtained from our graph theory strategy 1 with five cortical masks, namely, from auditory-motor integration, Wernicke’s, Broca’s F3 opercularis, Broca’s F3 triangularis, and Broca’s F3 orbitalis networks (Sepulcre, 2015). We obtained an overlap index of the stuttering connectivity map versus the rest of the language-related connectivity maps by extracting the intensity of the weighted degree centrality score in the stuttering network divided by the size of the corresponding mask.
