13. Dexamethasone-induced reactivation of bovine herpesvirus type 5 latent infection in experimentally infected rabbits results in a broader distribution of latent viral DNA in the brain
Bovine herpesvirus type 5 (BHV-5) is a major agent of meningoencephalitis in cattle and establishes latent infections mainly in sensory nerve ganglia. The distribution of latent BHV-5 DNA in the brain of rabbits prior to and after virus reactivation was studied using a nested PCR. Fifteen rabbits inoculated intranasally with BHV-5 were euthanized 60 days pos

14. Vascular supply of the central nervous system of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
The vascularization of the central nervous system of the snail Megalobulimus oblongus was studied by injection of carmine-gelatin solution into the arterial system and using a histochemical technique for the detection of alkaline phosphatase. The central nervous system of M. oblongus is irrigated by the anterior aorta, from which a series of small branches e

15. 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

16. Spect cerebral e ressonancia magnetica na doença de Machado-Joseph
Machado-Joseph disease (MJD) is the most frequently encountered autossomal dominant spinocerebellar ataxia in Brazil and in most parts of the eastem world. There are no reports on brain SPECT imaging with 99mTc-HMPAOand magnetic resonance imaging (MRI) in patients with genetically proven MJD (MJD/SCA3). Objectives : The purpose of this report was to perform

17. Potencial evocado somotossensorial por estimulação do nervo mediano nas lesões Vasculares cerebrais hemisfericas : estudos dos potenciais de media latencia em relação a lesões cerebrais documentadas por ressonancia magnetica do cranio e ao potencial N20
Middle latency somatosensory evoked potentials were recorded by electrical stimulation of the median nerve at the wrist, in 43 patients with hemispheric cerebrovascular lesions. Forty two patients were examined within the third and fourth weeks, and in one case, in the fourth month afier a stroke. Ali the lesions were documented by Magnetic Resonance Imaging

18. Epoxyeicosanoids as mediators of neurogenic vasodilation in cerebral vessels
Epoxyeicosatrienoic acids (EETs) are potent vasodilators produced from arachidonic acid by cytochrome P-450 (CYP) epoxygenases and metabolized to vicinal diols by soluble epoxide hydrolase (sEH). In the brain, EETs are produced by astrocytes and the vascular endothelium and are involved in the control of cerebral blood flow (CBF). Recent evidence, however, s

19. The temporal lobe is a target of output from the basal ganglia.
The basal ganglia are known to receive inputs from widespread regions of the cerebral cortex, such as the frontal, parietal, and temporal lobes. Of these cortical areas, only the frontal lobe is thought to be the target of basal ganglia output. One of the cortical regions that is a source of input to the basal ganglia is area TE, in inferotemporal cortex. Th

21. Development of the nervous system of Aplysia californica.
The ability to grow the marine molluse Aplysia under laboratory conditions allows a detailed study of the formation of the nervous system and of the development of specific identified cells. I have found that the ganglia develop in a specific temporal order. Cerebral and pedal ganglia develop at hatching, the abdominal, pleural, and osphradial ganglia 3 week

22. Does signal-attenuation on high-field T2-weighted MRI of the brain reflect regional cerebral iron deposition? Observations on the relationship between regional cerebral water proton T2 values and iron levels.
T2-weighted MRI shows attenuated signals from the basal ganglia, such signal attenuation being more evident at high magnetic field strengths of 1.5 tesla (T). The basal ganglia contain high levels of iron, and it has been suggested that these iron deposits lead to shortening of bulk water T2 protons via a mechanism involving diffusion of water through local

23. Akinetic mutism and bilateral anterior cerebral artery occlusion
Three cases of bilateral anterior cerebral artery occlusion are presented with akinetic mutism. The anatomical distribution of the infarction in these patients combined with cases in the literature suggests that this syndrome can have a localizing value for the clinician. If increased intraventricular pressure is not present, the clinician can suspect a bila

24. Central localization of plasticity involved in appetitive conditioning in Lymnaea
Learning to associate a conditioned (CS) and unconditioned stimulus (US) results in changes in the processing of CS information. Here, we address directly the question whether chemical appetitive conditioning of Lymnaea feeding behavior involves changes in the peripheral and/or central processing of the CS by using extracellular recording techniques to monit
