The associative-semantic network for words and pictures: Effective connectivity and graph analysis

► We applied graph analysis to the associative-semantic network measured with fMRI. ► Nodes in left occipital and temporal lobe fell into two 'communities'. ► Community 1 left vOT, anterior fusiform gyrus, hippocampus and IPS. ► Community 2 corresponded to the classical perisylvian language areas. ► The two subsystems were linked via vOT and GTm.
