Fig. 4.

Luxol-fast-blue & nuclear-fast-red (LFB-NFR) stains and their corresponding fiber orientation maps. In the in-plane 360° fiber orientation maps different hues (according to the HSV colormap) depict different fiber orientations. In the horizontal-vertical dominant fiber projection it is easier to appreciate vertical and horizontal fibers, e.g., in the corpus callosum. Tu: tumor; CC: corpus callosum (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article).
