The presence of a terminal nerve in the avian brain has recently been reported. As the terminal nerve in other classes of vertebrates contains luteinizing hormone-releasing hormone (LHRH), we used immunocytochemistry to determine whether the pigeon terminal nerve also contained LHRH. We found LHRH-immunoreactivity in the olfactory nerve and in the olfactory bulb. The distribution of LHRH neurons was similar to the LHRH neuronal migration pathway during development.
