1. Estudo das aferências imunorreativas ao hormônio concentrador de melanina (MCH) do núcleo accumbens, no rato Long-Evans (Rattus norvegicus). / Study of melanin-concentrating hormone (MCH) immunoreactive inputs of nucleus acumbens, in rats Long-Evans (Rattus norvegicus) .
O MCH é um neuropeptídeo sintetizado preferencialmente no hipotálamo que exibe projeções para todo o neuroeixo, podendo modular vários processos fisiológicos, como a ingestão aguda de alimento. Um alvo de suas projeções é o núcleo accumbens (Acb), componente do estriado ventral envolvido na recompensa de estímulos hedônicos. Nossa contribuiçã

2. Retrograde trans-synaptic transfer of green fluorescent protein allows the genetic mapping of neuronal circuits in transgenic mice
The function of the nervous system is a consequence of the intricate synaptic connectivity of its neurons. Our understanding of these highly complex networks has profited enormously from methods used over the past two decades that are based on the mechanical injection of tracer molecules into brain regions. We have developed a genetic system for the mapping

3. Connections of the hyperstriatum ventrale of the domestic chick (Gallus domesticus).
The intermediate part of the medial component of the hyperstriatum ventrale (IMHV) of the chick telencephalon is implicated in the learning process of imprinting. The afferent connections of this region were investigated using the retrograde neuronal tracers horseradish peroxidase (HRP), nuclear yellow and fast blue. Labelled cells were found (i) ipsilateral

4. Selective parasympathetic innervation of subcutaneous and intra-abdominal fat — functional implications
The wealth of clinical epidemiological data on the association between intra-abdominal fat accumulation and morbidity sharply contrasts with the paucity of knowledge about the determinants of fat distribution, which cannot be explained merely in terms of humoral factors. If it comes to neuronal control, until now, adipose tissue was reported to be innervated

5. Multiple origins of cerebellar cholinergic afferents from the lower brainstem in the gerbil.
The possible origins of cerebellar cholinergic afferents from the lower brainstem of the gerbil were examined using immunohistochemistry combined with retrograde neuronal labelling techniques. Choline acetyltransferase (ChAT) monoclonal antibody was used in conjunction with a retrogradely transported tracer, horseradish peroxidase (HRP). The use of this tech

6. Galanin: a hypothalamic-hypophysiotropic hormone modulating reproductive functions.
Galanin (GAL) is widely distributed in the peripheral and the central nervous systems. In the brain, the highest GAL concentrations are observed within the hypothalamus and, particularly, in nerve terminals of the median eminence. This location, as well as GAL actions on prolactin, growth hormone, luteinizing hormone (LH), and LH-releasing hormone (LHRH) sec

7. The transneuronal spread phenotype of herpes simplex virus type 1 infection of the mouse hind footpad.
The mouse hind footpad inoculation model has served as a standard laboratory system for the study of the neuropathogenesis of herpes simplex virus type 1 (HSV-1) infection. The temporal and spatial distribution of viral antigen, known as the transneuronal spread phenotype, has not previously been described; nor is it understood why mice develop paralysis in
