Photomicrographs of coronal sections through the dorsal horn of the tree pangolin spinal cord stained for Nissl (a), neuronal nuclear marker (NeuN, b), and calbindin (c) showing the architectonic appearance of Rexed laminae 1 – 4 (Sp1, Sp2O, Sp2I, Sp3, and Sp4). These photomicrographs correspond to level 5 depicted in Figures 2 and 3.
