Fig. 3.

A 3-D rendering of the venous density map of all 24 participants in G_app combined. This map was generated by transforming all detected veins from the scans of the participants to the MNI152 template. For each point on the expanded ventricular surface, all veins within a radius of 15 mm are counted. The colours represent a vein count ranging from low (blue, at least one vein at that location in a participant of G_app) to high (red, on average four veins within a 15 mm radius at that location)
