Research Abstract |
Gonadotropin-inhibitory hormone (GnIH) is a novel avian hypothalamic neuropeptide which plays important roles in the hypothalamo-pituitary gonadal axis. The previous study showed that the most prominent GnIH-immunoreactive fibers were seen in the median eminence of the hypothalamus and in the dorsal motor nucleus of the vagus (DMV) in the medulla oblongata, showing GnIH might participate not only in neuroendocrine functions but also in autonomic functions. In this study, we investigated the neural connections between the paraventricular nucleus in the hypothalamus and the DMV. In addition, the receptor for GnIH was localized in the DMV sending efferent fibers into the visceral tissues.
