Identification of intercalated (ITC) cell clusters. Two adjacent coronal sections of the rat amygdala (100-μm thickness) are shown. A: counterstaining with cresyl violet. B: distribution of immunoreactivity for μ-opioid receptors (μORs). Note that darkly stained clusters of cells on the section counterstained with cresyl violet (arrows in A) correspond to patches of dense immunolabeling for μORs (arrows in B). BL, basolateral; CeL, central lateral nucleus; CeM, central medial nucleus; OT, optic tract; ITCd, dorsal ITC cluster; ITCv, ventral ITC cluster; ITCm, large (main) ITC cluster.
