FIGURE 5.

Low (a–d) and high (insets in a, c, d) magnification photomicrographs of the anterior (CoA) and posterior (CoP) cortical amygdaloid nuclei of the amygdaloid body of the tree pangolin stained for neuronal nuclear marker, NeuN (a), myelin (b), parvalbumin (c), and calbindin (d). Note the presence of larger neurons, increased myelin density, occasional parvalbumin immunostained neurons, and lower density of calretinin immunopositive structures in the CoP compared with the CoA. The insets in a, c, d are high magnification images of NeuN (a), parvalbumin (c), and calbindin (d) stained neurons in the CoA and CoP. In all images, dorsal is to the top and medial to the left. Scale bar in (d) = 1 mm and applies to (a)–(d). Scale bar in inset (d) = 25 μm and applies to all insets. See list for abbreviations
