1. Small-scale environmental enrichment and exercise enhance learning and spatial memory of Carassius auratus, and increase cell proliferation in the telencephalon: an exploratory study
Carassius auratus is a teleost fish that has been largely used in behavioral studies. However, little is known about potential environmental influences on its performance of learning and memory tasks. Here, we investigated this question in C. auratus, and searched for potential correlation between exercise and visuospatial enrichment with the total number of

2. Leukoencephalomalacia in horses associated with immature corn consumption
RESUMO: A leucoencefalomalácia dos equinos (ELEM) é uma doença causada pela ingestão de micotoxinas (fumonisinas) produzidas por fungos do gênero Fusarium que infectam o milho e/ou seus subprodutos. A doença tem sido descrita pela ingestão de milho maduro com umidade acima de 15% em temperatura ambiente abaixo de 20°C. O objetivo deste trabalho foi

3. Neuroscience: unveiling the brain of Saimiri collinsi (Squirrel Monkey)
Abstract Behavioral intelligence among non-human primates is a somewhat puzzling area to study, since it is closely linked to the morphology of the central nervous system. However, this morphology is still unknown to science in the case of Saimiri collinsi. As a means of assisting future studies on the social behavior of this species, we analyzed the brains

4. Gross brain morphology of Rhamdia quelen (Quoy & Gaimard 1824) (Ostariophysi: Siluriformes: Heptapteridae)
Abstract The brain gross morphology of Rhamdia quelen is described and compared with seven species of six genera of Heptapteridae. Interspecific variation in shape, size, and position of brain subdivisions was observed in all examined species. The posterior position of the hypophysis on the hypothalamus and presence of a lateral subdivision on the lobus faci

5. Comparative gross encephalon morphology in Callichthyidae (Teleostei: Ostariophysi: Siluriformes)
RESUMO Callichthyidae é composto por Callichthyinae e Corydoradinae, ambos morfologicamente distintos e monofiléticos. Apesar do consenso em relação ao mofiletismo da família, as relações de cerca de 80% de suas espécies, atualmente incluídas no gênero Corydoras, permanecem pouco conhecidas. Apesar da grande quantidade de informação osteológica

6. POLIOENCEFALOMALACIA EM RUMINANTES / POLIOENCEPHALOMALACIA IN RUMINANTS
In the first portion of this thesis, epidemiology, clinical signs and distribution of lesions in the brain of thirty one cases of polioencephalomalacia (PEM) in cattle from the Southern (13 cases) and Midwestern (18 cases) Brazil were studied. Morbidity (0.04%-6.66 %), mortality (0.04%-6.66 %), and lethality (50%-100%) rates were similar in both regions stud

7. Estudo da distribuição da proteína S100b em encéfalo de ratos. / Distribution of the S100b protein specific in brain of the rats.
S100b protein is expressed primarily by astroglia in the brain, and practice functional implication of S100b secretion by astrocytes into the extracellular space is scant but there is substantial evidence that secreted glial S100b exerts trophic or toxic effects depending on its concentration. We pr

8. Agonistic-like responses from the torus semicircularis dorsalis elicited by GABA A blockade in the weakly electric fish Gymnotus carapo
Findings by our group have shown that the dorsolateral telencephalon of Gymnotus carapo sends efferents to the mesencephalic torus semicircularis dorsalis (TSd) and that presumably this connection is involved in the changes in electric organ discharge (EOD) and in skeletomotor responses observed following microinjections of GABA A antagonist bicuculline into

9. Efeitos da clorfeniramina na aprendizagem, memória e ansiedade de teleósteos submetidos à ablação telencefálica.
The teleost telencephalon provides a good opportunity for studying the function of the vertebrate limbic system because it is simple and present homologies to the limbic structure of higher vertebrates, with hippocampus and amygdala. These animals shows only one area of projection to the telencephalon (Ekström et al., 1995), which has been well preserved th

10. Histamina facilita a aprendizagem em uma tarefa de escolha espacial em Carassius auratus.
O objetivo deste trabalho foi investigar, em peixes da espécie Carassius auratus submetidos à ablação telencefálica, o efeito do bloqueio do receptor H1 em uma tarefa de escolha espacial utilizando um teste de labirinto em T com reforço positivo. Sessenta e nove peixes foram submetidos à cirurgia para a remoção de ambos os lobos telencefálicos cinc

11. The origin of cortical neurons
Neurons of the mammalian cerebral cortex comprise two broad classes: pyramidal neurons, which project to distant targets, and the inhibitory nonpyramidal cells, the cortical interneurons. Pyramidal neurons are generated in the germinal ventricular zone, which lines the lateral ventricles, and migrate along the processes of radial glial cells to their positio

12. Displasias corticais associadas a epilepsia : delineamento de uma nova sindrome, revisão de conceitos localizacionais e proposta de uma nova classificação
Modemneuro:imagingtechniques current1y allows lin vivo I identification of cortical dysplastic lesions in patients previously thought to have cryptogenic epilepsies. These lesions constitute an heterogenous group of disorders from clinicall anatomical, histopathological, and pathogenetic standpoints. The fact that such heterogeneity is not readily realized o
