Immunohistochemical mapping of enkephalins, NPY, CGRP, and GRP in the cat amygdala.
This immunohistochemical study shows a wide distribution of neuropeptides in the cat amygdala. Neuropeptide Y is present along the whole amygdaloid complex, and fibers and cell bodies containing neuropeptide Y are observed in all the nuclei studied. Leucine-enkephalin-, gastrin-releasing peptide/bombesin-, and calcitonin gene-related peptide-immunoreactive fibers and perikarya are observed only in discrete nuclei of the amygdaloid complex, whereas only fibers -but no cell bodies- containing methionine-enkephalin-Arg6-Gly7-Leu8 have been observed. No immunoreactivity has been found for gamma-melanocyte-stimulating hormone, dynorphin A (1-17), or galanin. These data are compared with those reported in the amygdala of other mammals.
