Photomicrographs showing the distribution of ChAT-ir profiles in the hippocampus
and thalamus of Sus scrofa domesticus. Coronal sections
(A, B) showing ChAT-ir labeling in the dorsal and
temporal aspects of the hippocampal formation and dentate gyrus (DG) and
thalamic nuclei. Insert in B shows a cholinergic bipolar
hippocampal neuron. Low (C) and high power (D,
E) photomicrographs of a Nissl counterstained section showing
ChAT-ir fibers within the polymorphic (C, D) and
molecular layer (C, E) of the dentate gyrus. Scale
1000 μm A, B; 100 μm C.
