“…The distribution and location of hypothalamic nuclei in P. axelrodi is similar to what has been reported for D. rerio (Wullimann et al, 1996), C. auratus (Peter, Gill, 1975;Fryer, Maler, 1981), O. latipes (Anken, Bourrat, 1998;Ishikawa et al, 1999), D. labrax (Cerdá-Reverter et al, 2001) and S. salar (Peter et al, 1991). In general, neuron distribution, size, shape and staining pattern are similar to those previously reported for other related species.…”

“…However, other related species like lubine, D. labrax (Cerdá-Reverter et al, 2001), and the Atlantic salmon, Salmo salar Linnaeus, 1758 (Peter et al, 1991), show some differences, particularly regarding the distribution of the magnocellular preoptic nuclei (PM), which precludes over generalizing the reported pattern. Detailed studies in other species have to be performed in order to fully characterize this brain region in ostariophysians.…”

“…Based on this evidence, which cellular types comprise the PM is controversial and can vary between species. Variations in the size of PM cells can be due to the amount of their neurosecretory content (Cerdá-Reverter et al, 2001). Similarly, Gómez-Segade et al (1986) reported that in some species PM cellular neuron size could change seasonally.…”

“…Different reports indicate that neurons in the Hc secrete CCK, CRH, Galanin, NPY, SST, TRH and UI, as well as neurotransmitters like DA, GABA, serotonin and noradrenalin (Norris, 2007;Cerdá-Reverter, Canosa, 2009). Regarding the PTN, it has been reported that neurons in this nuclei secrete TRH (Cerdá-Reverter et al, 2001) Tanycytes are observed along all three hypothalamic regions described in P. axelrodi. They surround the diencephalic ventricle and the posterior (PR) and lateral (LR) recesses.…”

Topological and histological descriptions of the preoptic area and hypothalamus of the cardinal tetra Paracheirodon axelrodi were performed. Standard histological paraffin sections were used and stained with Nissl technique, and plastic sections for high-resolution optic microscopy (HROM). The preoptic area showed some differences related to the location of the magnocellular preoptic nucleus (PM) and the size of the neurons in this region, as they were the biggest in all the preoptic area. Additionally, within the preoptic area, the different structures that comprise the organum vasculosum of the lamina terminalis (OVLT) were identified and characterized. The hypothalamus could be subdivided in three regions -the ventral, the dorsal and the caudal hypothalamic regions -neuron morphology, size and staining pattern were similar in all of them.Keywords: Brain, High resolution optic microscopy (HROM), Organum vasculosum of the lamina terminalis (OVLT).Se realizó la descripción topológica e histológica del área preóptica e hipotálamo en el Neón cardenal Paracheirodon axelrodi. Se usaron cortes obtenidos con tecnicas histológicas estándar, coloreados con técnica de Nissl y secciones en resina con microscopía óptica de alta resolución (MOAR). El área preóptica muestra algunas diferencias relacionadas con la localización del núcleo preóptico magnocelular (PM) y el tamaño de algunas neuronas en esta región, puesto que estas eran las más grandes de toda el área preoptica. Adicionalmente, dentro del área preóptica, fue posible identificar y caracterizar las diferentes estructuras que componen el órgano vasculoso de la lámina media (OVLM). El hipotálamo puede sudividirse en tres zonas: la zona hipotalámica ventral, la zona hipotalámica dorsal y la zona hipotalámica caudal. La morfología de las neuronas de los núcleos que comprenden las diferentes zonas del hipotálamo tiene tamaño, forma y coloración similar.Palabras Clave: Cerebro, Microscopía óptica de alta resolucion (MOAR), Órgano vasculoso de la lámina terminal (OVLT).

“…As in many other teleosts [Northcutt and Davis, 1983;Cerdá-Reverter et al, 2001;Northcutt, 2006], the rostral pole of the telencephalon is dominated by Dld, dorsomedially, and Dl-v, laterally ( fig. 1 A; section 18).…”

Although the telencephalon of ray-finned fishes has garnered considerable attention from comparative neuroanatomists, detailed descriptions of telencephalic organization are available for only a few species. This necessarily limits our understanding of telencephalic evolution, particularly in light of the extraordinary diversity of ray-finned fishes. Thus, we have charted the cyctoarchitecture of the telencephalon of the African cichlid fish, Astatotilapia (Haplochromis) burtoni. We examined tissue sectioned in the transverse plane, and categorized cell groups based on size, shape, and staining intensity of cells, the density and distribution of cells, cell-poor zones, and relationship of cell groups to the anterior commissure and external sulci. In addition, to facilitate visualization of the transitions among cell groups, we aligned and animated a series of 100 sequential brain sections. We found that the A. burtoni telencephalon was similar to other percomorphs in being highly elaborated with many distinct cell groups. In the pallium, Dm, Dl, and Dc had a large number of cell groups, whereas Dd and Dp were more uniform. Although we recognized many similarities between the pallium of A. burtoni and other teleosts, we also recognized two cell groups (Dl-g and Dm-2) that might represent specializations of cichlids. We found that the subpallium had a similar organization to that of other ray-finned fishes.

Annual fish have become attractive study models for a wide range of disciplines, including neurobiology. These fish have developed different survival strategies. As a result, their nervous system is under considerable selective pressure when facing extreme environmental situations. Fish from the Austrolebias group exhibit rapid neurogenesis in different brain regions, possibly as a result of the demanding conditions of a changing habitat. Knowledge of cerebral histology is essential for detecting ontogenic, anatomical, or cytoarchitectonic changes in the brain during the short lifespan of these fish, such as those reflecting functional adaptive plasticity in different systems, including sensory structures. The generation of an atlas of Garcialebias charrua (previously known as Austrolebias charrua) establishes its anatomical basis as a representative of a large group of fish that share similarities in their way of life. In this work, we present a detailed study of both gross anatomy and microscopic anatomy obtained through serial sections stained with the Nissl technique in three orientations: transverse, horizontal, and parasagittal planes. This atlas includes accurate drawings of the entire adult brain of the male fish Garcialebias charrua, showing dorsal, ventral, and lateral views, including where emergence and origin of cranial nerves. This brain atlas allows us to understand histoarchitecture as well as the location of neural structures that change during adult neurogenesis, enabling comparisons within the genus. Simultaneously, this atlas constitutes a valuable tool for comparing the brains of other fish species with different behaviors and neuroecologies.
