Examination of the involved networks and connected hubs in the stroke region. a Projection density map of the five largest regions in the stroke incidence mask (dashed line in Fig. 4b) as primary injection sites (y-axis) and their top five connectivity targets, ranked by connectivity strength (x-axis). Cell color in both the left and middle panels represents normalized projection volume between the primary injection (y-axis) and target structure (x-axis). b Matrix of the largest ten labels, as primary injection sites (y-axis), in the stroke area and their ten targets most common across all injection sites. c Snapshot of an interactive network graph of the largest 25 labels in the stroke mask and their 25 most common targets, highlighting example hubs (regions with a high degree of connectivity) inside and outside the stroke region. Blue nodes (circles representing brain regions) are regions inside the stroke and purple nodes are outside. Example hubs within the stroke: CP: caudoputamen, PIR: piriform area, SS: somatosensory areas.
