TABLE 9.

Left-hemisphere perisylvian structural connectivity predictive of NAVS scores on complex structures, after partial regression of scores on less complex structures. The label “dorsoventral” is given to connections between frontal and temporal hubs, as well as between regions that are considered part of separate streams
