Recently, the zebrafish has been extensively used for studying the development of the central nervous system (CNS). However, the zebrafish CNS has been poorly analyzed in the adult. The cholinergic/cholinoceptive system of the zebrafish CNS was analyzed by using choline acetyltransferase (ChAT) immunohistochemistry and acetylcholinesterase (AChE)(More)
The distribution and morphologic features of calcium-binding protein- (calbindin D-28k, calretinin, neurocalcin, and parvalbumin) immunoreactive elements were studied in the macaque monkey olfactory bulb by using specific antibodies and the avidin-biotin-immunoperoxidase method. A characteristic laminar pattern of stained elements was observed for each(More)
The distribution of reduced nicotinamide adenine dinucleotide phosphate (NADPH)-diaphorase activity was histochemically investigated in the Japanese quail brain. This enzyme is now considered responsible for the synthesis of nitric oxide, a novel neural messenger whose distribution has not been described in the avian brain until now. The histochemical(More)
The distribution of NADPH-diaphorase (ND) activity was histochemically investigated in the brain of the frog Rana perezi. This technique provides a highly selective labeling of neurons and tracts. In the telencephalon, labeled cells are present in the olfactory bulb, pallial regions, septal area, nucleus of the diagonal band, striatum, and amygdala.(More)
The effects of olfactory deprivation on the density of neuronal populations expressing the calcium-binding proteins calbindin D-28k, calretinin, and parvalbumin in the anterior olfactory nucleus of the rat were studied immunohistochemically in 60-day-old rats subjected to unilateral naris closure on the day of birth. The neuronal populations were(More)
The distribution of chemically identified neuronal populations was studied in the glomerular layer of the rat olfactory bulb using calcium-binding protein immunocytochemistry combined with acetylcholinesterase histochemistry. Four calcium-binding proteins (calbindin D-28k, parvalbumin, calretinin, and neurocalcin) were analyzed in the periglomerular region(More)
The distribution of choline acetyltransferase (ChAT)-immunoreactive and acetylcholinesterase (AChE)-positive fibers and terminals was analyzed in the hippocampal formation of macaque monkeys subjected to transection of the fimbria/fornix. Cases with either unilateral or bilateral transections were prepared, with post transection survival times ranging from(More)
Nitric oxide synthase activity was studied by means of NADPH-diaphorase activity and nitric oxide synthase immunoreactivity in the main and accessory olfactory bulbs of the frog Rana perezi and the newt Triturus marmoratus. In both species, NADPH-diaphorase staining was observed in all olfactory fibers. Vomeronasal fibers were NADPH-diaphorase-positive in(More)
The olfactory bulbs of Barbus meridionalis, Carassius carassius, Chondrostoma polylepis, Cyprinus carpio, Tinca tinca and Salmo gairdneri were examined by two variants of the Golgi technique. We report, for the first time, the existence of ruffed cells in these species. This neuronal type shows a characteristic morphology and location. Overall, these cells(More)
A recent study of the distribution of NADPH-diaphorase (NADPHd) and nitric oxide synthase (NOS) in a turtle brain (Brüning et at. [1994]: J. Comp. Neurol. 348:183-206) has revealed that these enzymes are not only widely distributed throughout the brain, but also seem to be colocalized with other classical neurotransmitters, such as catecholamines and(More)
