Acetylcholinesterase immunolabeling in the tree shrew striatum. (A–C) Low magnification images of AchE labeling in the rostral (A), mid (B), and caudal (C) striatum showing a patchy distribution of immunostaining. (D) Detail of a patch of low AchE-ir (black arrows) in the rostral caudate. (E,F) Detail of AchE labeled cells (open arrows) in the caudate (E) and putamen (F). Some of these cells present labeling in the initial segment of a process [arrowheads in (E)]. Coordinates indicate the orientation of the sections in the figure (D, dorsal; L, lateral). ac, anterior commissure; C, caudate; cc, corpus callosum; ic, internal capsule; GP, globus pallidus; P, putamen. Scale bars: 1 mm in (A–C); 100 μm in (D); 50 μm in (E–F).
