FIGURE 6.

Lower (a–d) and higher (e–n) magnification photomicrographs of the periamygdaloid cortex (PAC) within the amygdaloid body of the tree pangolin stained for neuronal nuclear marker (NeuN, a, e, j), parvalbumin (PV, b, f, k), calbindin (CB, c, g, l), calretinin (CR, d, h, m), and neurofilament H (NFH, i, n). Both the medial (PACm, e–i) and lateral (PACl, j–n) periamygdaloid cortical areas exhibit a trilaminate organization (layers 1, 2, 3). 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 (n) = 100 μm and applies to (e)–(n). See list for abbreviations
