Abstract

The arrangement of the enteric nerve plexuses in the colon of the guinea-pig and the distributions and projections of chemically specified neurons in this organ have been studied. Immunoreactivity for neuron specific enolase was used to examine the total population of neurons and individual subpopulations were studied using antibodies raised against calbindin, calcitonin gene-related peptide (CGRP), leu-enkephalin, gastrin releasing peptide (GRP), galanin, gamma aminobutyric acid, neurokinin A, neuropeptide Y (NPY), somatostatin, substance P, tyrosine hydroxylase and vasoactive intestinal peptide (VIP). Neuronal pathways within the colon were lesioned using myotomy and myectomy operations an..
