the distribution of acetylcholinesterase and of two neuropeptide ( substance p and calcitonin gene-related peptide ) immunoreactivities has been investigated in sensory neurons of lumbosacral dorsal root ganglia during chick embryo development , combining immunolocalization of neuropeptides with simultaneous histochemical detection of acetylcholinesterase , in order to study co-localization of the two peptides and their relations with acetylcholinesterase .
