TLDR
An immunocytochemical unlabeled antibody enzyme technique has been applied to localize mammalian-like immunoreactive luteinizing hormone-releasing hormone (ir-LH-RH) in central nervous tissue of Pacific lamprey (Entosphenus tridentata; anadromous spawning migrants) and of Pacific hagfish (Eptatretus stouti, sexually undifferentiated and mature) as discussed by the authors.About:

Primary structure of gonadotropin-releasing hormone from lamprey brain.
TL;DR: A second form of GnRH (lamprey II GnRH), representing about 10% of the total GnRH immunoreactive material in the brain, was isolated; its amino acid composition differs by 3 residues from lamprey I GnRH, which elevates plasma estradiol in adult female lampreys.
Journal ArticleDOI
Primary structure and biological activity of a third gonadotropin-releasing hormone from lamprey brain.
TL;DR: It is proposed based on the biological activity of lampreys GnRH-III in these studies and the occurrence of this peptide during metamorphosis in lampreys, that both lamprey Gn RH-I and -III are neurohormones involved in reproduction in lamprey.

The System of Cerebrospinal Fluid-Contacting Neurons
I. Vigh-Teichmann,Béla Vigh +1 more
TL;DR: The CSF-contacting neurons represent a specialized, but phylogenetically old cell type, a "protoneuron" in the vertebrate brain, which may be derived phylogenetically by inversion of the ciliated neurons found in the plate-like nervous system of more primitive deuterostomians.
Journal ArticleDOI
Evolution of Vertebrate Olfactory Systems
TL;DR: A phylogenetic analysis of central olfactory projections indicates that at least three distinct olf factory subsystems may be broadly present in vertebrates and that a fourth, the accessory vomeronasal system, arose in tetrapods.

Thyrotropin-releasing hormone (TRH): distribution in hypothalamic and extrahypothalamic brain tissues of mammalian and submammalian chordates
TL;DR: Findings indicate that TRH is distributed throughout the vertebrate kingdom, and has an ancient lineage.

Regulatory peptides of the hypothalamus.
W Vale,Catherine Rivier,M Brown +2 more
TL;DR: The peptides that are the principal subject of this review are originally detected in extracts of the hypothalamus as a result of their effects on the secretory functions of the anterior pituitary gland and are shown to have unequivocal hypophysiotropic activities by numerous investigators.

The brain of the lamprey in a comparative perspective.
TL;DR: The structural organization of the brain and spinal cord of the lamprey is surveyed and it is felt justified in using in the present treatise the term “lamprey” without any further specification.
Journal ArticleDOI
Production and characterization of an antiserum to synthetic gonadotropin-releasing hormone.
TL;DR: Biologically active hypothalamic extract and LH-RH produced parallel 125 I-LH-RH-binding inhibition curves, providing immunochemical support for the identity of the native releasing hormone with synthetic LH- RH.
