“…In zebrafish, the tectal TH-ir fibers could originate from both pretectum (present results) and from the locus coeruleus (Ma 1994b). The location observed in zebrafish is similar to that described in the rest of the non-mammalian vertebrates (Marı´n et al 1999;Smeets et al 1987;Rodman and Karten 1995). However, the dopaminergic inputs in the superior colliculus of mammals originate only from the midbrain cell groups (Arce et al 1994).…”

We analyzed the distribution of tyrosine hydroxylase immunoreactivity in the central nervous zones involved in the processing of visual information during zebrafish ontogeny, employing a segmental approach. In the retina, we observed immunolabeled cells in the inner nuclear layer after hatching. From the juvenile stages onwards, some of these cells presented two immunolabeled processes towards the inner and outer plexiform layers of the retina, which are identified as interplexiform cells. In the adult zebrafish retina, we have identified two cellular types displaying immunoreactivity for tyrosine hydroxylase: interplexiform and amacrine cells. In the optic tectum, derived from the mesencephalon, no immunolabeled neurons were observed in any of the stages analyzed. The periventricular gray zone and the superficial white zone display immunostained neuropile from the end of fry life onwards. At the 30-day postfertilization, the tyrosine hydroxylase immunoreactive neuropile in the optic tectum presents two bands located within the retinorecipient strata and deeper strata, respectively. All diencephalic regions, which receive direct retinal inputs, show immunolabeled cells in the preoptic area, in the pretectum, and in the ventral thalamus from embryonic stages onwards. During the fry development, the immunolabeled neurons can be observed in the periventricular pretectum from 15-days postfertilization and in both the ventrolateral thalamic nucleus and suprachiasmatic nucleus from 30-days postfertilization. The transient expression of tyrosine hydroxylase is observed in fibers of the optic tract during fry and juvenile development. The existence of immunolabeled neuropile in the zebrafish retinorecipient strata could be related to the turnover of retinotectal projections.

“…According to the currently described tripartite organization of the pretectal cell groups in relation to the posterior commissure, the TH‐ir cells will be included in the commissural pretectal division, as in amphibians and some lungfishes (López & González, ; Morona, Ferrán, Puelles, & González, , ), separated from the serotonergic pretectal group that lies in the precommissural division (López & González, ). These cells are probably the source of the prominent dopaminergic innervation to the tectum, as it is inferred from the sagittal sections, and they may play an important role in the modulation of the retinotectal visual input, as it has been observed in other vertebrates (Marín et al, ; Rodman & Karten, ; Sánchez‐Camacho, Marín, & González, ). In addition, the superficial pretectal zone of cladistians has a dense innervation of TH‐ir fibers, zone that has been identified in Polypterus as receiving primary retinofugal projections (Repérant, Rio, Miceli, Amouzou, & Peyrichoux, ), suggesting a CA influence on these retinorecipient areas.…”

Cladistians are a group of basal nonteleost actinopterygian fishes that represent an interesting group for the study of primitive brain features, most likely present in the ancestral Osteichthyes. We have investigated the catecholaminergic (CA) systems in the brain of two representative cladistian species, the bichir Polypterus senegalus and the reedfish Erpetoichthys calabaricus, by means of antibodies against tyrosine hydroxylase (TH; the first enzyme in the synthesis of catecholamines) and dopamine (DA). Double immunohistofluorescence was performed for simultaneous detection of TH with nitric oxide synthase, choline acetyltransferase, calbindin, calretinin, and serotonin, aiming to accurately establish the localization of the CA neurons and to assess possible interactions between these neuroactive substances. All forebrain CA groups of cladistians are dopaminergic, whereas noradrenergic cells are located within the rhombencephalon. Distinct groups of DA immunoreactive (DA‐ir) cells were observed in the olfactory bulb, subpallium, and preoptic area of the telencephalon. Hypothalamic groups were detected in the suprachiasmatic nucleus, retrotuberal and retromamillary areas and, in particular, the paraventricular organ showed immunoreactivity to dopamine but not to TH. Diencephalic DA‐ir groups were detected in the prethalamus, posterior tubercle, and pretectum. A small DA‐ir cell population was observed in the midbrain tegmentum only in Polypterus. CA cell groups were also located in the locus coeruleus, solitary tract nucleus, and area postrema within the rhombencephalon, the spinal cord, and the retina. The comparison of these results with other vertebrates, using a neuromeric analysis, shows highly conserved traits in all vertebrates studied but also evidences particular characteristics of actinopterygian fishes.

“…A direct tectal connection from the isthmus has been found in all vertebrates studied so far [Nieuwenhuys et al, 1998]. In most teleosts this connection is only ipsilateral [Ebbesson and Vanegas, 1976;Grover and Sharma, 1981;Luiten, 1981;Sakamoto et al, 1981;Ito et al, 1982b;Northcutt, 1982;Vanegas and Ito, 1983;Zottoli et al, 1988;Yamamoto et al, 1999], as well as in the leopard frog [Wilczynski and Northcutt, 1977]; however, bilateral connections were found in other fish [Dunn-Meynell and Sharma, 1984;Sas and Maler, 1986] and amphibian species [Glasser and Ingle, 1978;Grobstein et al, 1978;Gruberg and Udin, 1978;Gruberg and Lettvin, 1980;Grobstein and Comer, 1983;Desan et al, 1987;Rettig, 1988;Marín et al, 1999].…”

Tectal afferents were studied in adult lampreys of three species (Ichthyomyzon unicuspis, Lampetra fluviatilis, and Petromyzon marinus) following unilateral BDA injections into the optic tectum (OT). In the secondary prosencephalon, neurons projecting to the OT were observed in the pallium, the subhipoccampal lobe, the striatum, the preoptic area and the hypothalamus. Following tectal injections, backfilled diencephalic cells were found bilaterally in: prethalamic eminence, ventral geniculate nucleus, periventricular prethalamic nucleus, periventricular pretectal nucleus, precommissural nucleus, magnocellular and parvocellular nuclei of the posterior commissure and pretectal nucleus; and ipsilaterally in: nucleus of Bellonci, periventricular thalamic nucleus, nucleus of the tuberculum posterior, and the subpretectal tegmentum, as well as in the pineal organ. At midbrain levels, retrogradely labeled cells were seen in the ipsilateral torus semicircularis, the contralateral OT, and bilaterally in the mesencephalic reticular formation and inside the limits of the retinopetal nuclei. In the hindbrain, tectal projecting cells were also bilaterally labeled in the dorsal and lateral isthmic nuclei, the octavolateral area, the sensory nucleus of the descending trigeminal tract, the dorsal column nucleus and the reticular formation. The rostral spinal cord also exhibited a few labeled cells. These results demonstrate a complex pattern of connections in the lamprey OT, most of which have been reported in other vertebrates. Hence, the lamprey OT receives a large number of nonvisual afferents from all major brain areas, and so is involved in information processing from different somatic sensory modalities.
