Distribution of Pha-L anterograde labeled fibers and terminals in the spinal dorsal horn projected from the ACC. A-B, One sample figure from a sagittal slice (A) showing that Pha-L labeled fibers and terminals were distributed in the laminae I-III of the spinal cord (c4) after Pha-L injection into one side of the ACC (B). The rectangled areas (1–5) in A were augmented in C-G respectively. Bars equal to 100 μm in A, 200 μm in B, 10 μm in C-G.
