Termination pattern of BDA labeled fibers arising from RMg. a–c an injection site in RMg (red dashed circle). d A C6 section showing the labeled fibers in both the ventral and lateral funiculi (red arrows). e A C6 section showing labeled fibers in the lateral funiculi (red arrows) and lamina 7, 8, 9, and 10. f A higher magnification of the rectangular area in e. Note labeled fibers in laminae 7–10. g An L4 section showing labeled fibers in both the ventral and lateral funiculi (red arrows). h An L4 section showing labeled fibers in bilateral dorsal horn and the dorsal part of the ventral horn. i A higher magnification of the right rectangular area in h. Note labeled fibers in laminae 1, 2, 4, and 5. j A higher magnification of the left rectangular area in h. Note few labeled fibers in lamina 3. k An S1 section showing labeled fibers in the lateral and ventral funiculi and in all laminae. Note there are more fibers in the lateral funiculus than in the ventral funiculus. l A higher magnification of the rectangular area in k. The scale bar 500 μm in a–c, 400 μm in d, 300 μm in g and k, 200 μm in e, and h, 100 μm in f, i, j, l, and the microphotograph in b.
