The Mytilus gonadal cycle in Vigo Estuary follows the histological pattern proposed by Lubet (1957, 1959) and the mantle tissue index varies depending on the number of gametes and is suitable as a gonadal index in this species.
Distribution of choline acetyltransferase immunoreactivity in the brain of an elasmobranch, the lesser spotted dogfish (Scyliorhinus canicula)

It is demonstrated for the first time that cholinergic neurons are distributed widely in the central nervous system of elasmobranchs and that their cholin allergic systems have evolved several characteristics that are unique to this group.

The findings suggest the conservation of developmental patterns in serotoninergic systems and enhance the importance of elasmobranchs for understanding the early evolution of this system in vertebrates.
A DiI-tracing study of the neural connections of the pineal organ in two elasmobranchs (Scyliorhinus canicula and Raja montagui) suggests a pineal projection to the midbrain GnRH-immunoreactive…

Results suggest that the midbrain sGnRHir nucleus is a part of the secondary pineal pathways and may be involved in light-mediated pineal regulation of brain function in elasmobranchs and other anamniotes.
Distribution and development of catecholaminergic neurons in the brain of the brown trout. A tyrosine hydroxylase immunohistochemical study.

The distribution of tyrosine hydroxylase immunoreactive (TH-ir) neurons in the brain of adult and developing trout is reported, and their significance for both comparative and developmental analysis is discussed.
New Insights on Saccus vasculosus Evolution: A Developmental and Immunohistochemical Study in Elasmobranchs

The early differentiation of GABAergic neurons and the presence of a conspicuous GABAergic saccofugal system are shared by elasmobranch and teleosts (trout), suggesting that GABA plays a key function in the SV circuitry.

Cholinergic systems in the midbrain of the eel were identified by using histochemical procedures for the demonstration of the enzymes choline acetyltransferase (ChAT) and acetylcholinesterase.…
Organization of catecholaminergic systems in the hypothalamus of two elasmobranch species, Raja undulata and Scyliorhinus canicula. A histofluorescence and immunohistochemical study.

- BiologyBrain, Behavior and Evolution
- 1993
Three catecholaminergic populations are identified in the hypothalamus of the painted ray, Raja undulata, and the small-spotted dogfish, suggesting differences in the metabolism ofcatecholamine and/or different functions.
