Reconstructions of transverse brain stem sections (from caudal to rostral) of three monkey cases showing the location (dark gray) of the tracer injections and the extent of the uptake area (light gray). (A–C) Case 1: The Tetramethylrhodamine dextran (TMR-DA) injection involved the oculomotor (nIII) and trochlear nucleus (nIV), but spared the C-group (C). (D–F) Case 2: CTB injection involved nIII, EW and the C-group and, to a minor extent, nIV. (G–I) Case 3: The TMR-DA injection was placed into the oculomotor nerve (NIII), and did not involve the motoneurons in nIII and nIV. Aq, aqueduct; CCN, central caudal nucleus; RN, red nucleus; 3V, third ventricle; INC, interstitial nucleus of Cajal. Scale bar, 500 μm.
