Orientation of VP, TREZ, TG. Key areas for our analyses are shown here: (1) the trigeminal principle nucleus (Vp), (2) The root entry zone (TREZ) where central glia are in the CNS side (GFAP, red), and Schwann cells on the ganglion side, and (3) trigeminal ganglion (TG). The cell bodies for infraorbital nerve (ION) occur in the distal parts of the combined V1/V2 but not in V3. Yellow boxes show sites for quantification.
