FIGURE 12.

High magnification photomicrographs of coronal sections through the tree pangolin brain showing the architectural appearance of the nuclei forming the rostral portion of the bed nuclei of the stria terminalis, including the rostral medial (RM), principal (Pr), rostral intermediate (RI), and rostral lateral (RL) divisions stained for neuronal nuclear marker (NeuN; a–d), myelin (e–h), calbindin (i–l), calretinin (m–p), orexin‐A (q–t), and neurofilament H (u–x). Note the variations in structural densities between the nuclei, which can be consistently employed to determine the extent of each of these nuclei. In all photomicrographs, medial is to the left and dorsal to the top. Scale bar in (x) = 50 μm and applies to all
