The purpose of the present experiments was to study the effects of a combined cholinergic and serotonergic denervation of the rat forebrain on spatial learning using the Morris water maze task. Experiment 1 compared the acute effects of a radiofrequency lesion of the septum, an intraventricular 5,7-dihydroxytryptamine (5,7-DHT) lesion, and a combined septal plus 5,7-DHT lesion. Although the 5,7-DH

Grafts of five different types of central cholinergic neurons, from the septal-diagonal band region, the nucleus basalis magnocellularis region (NBM), the striatum, the pontomesencephalic tegmentum of the brainstem, and the spinal cord, were compared with respect to their ability to grow and to reinnervate the cholinergically denervated hippocampal formation of adult rats. The areas were dissected

The survival and function of cross-species (mouse-to-rat) grafts of fetal mesencephalic dopamine (DA) neurons, implanted as a cell suspension in the striatum of rats with lesions of the mesostriatal DA system, have been studied in animals with and without immunosuppression induced by Cyclosporin A (CyA). At 6 weeks after grafting 3 out of 7 non-CyA treated animals showed some degree of graft survi

The aim of the paper is to investigate how material form and territorial complexity support and differentiate social interaction in urban consumption spaces. Spaces of consumption may well be the most socially mixed spaces in modern cities. Open-air markets provide excellent conditions to study these issues since they represent a broad, and often condensed, range of public situations in a consumpt

The forward-to-backward asymmetry of neutrons emitted in the 40Ca(γ,n0) reaction was measured at photon energies in the range of 27–50 MeV. An energy-dependent asymmetry was observed that is interpreted as evidence of interference between the isovector quadrupole resonance and the giant dipole resonance. Data analysis in terms of semiclassical and direct-semidirect models estimate the isovector qu

Volumetric blood flow measurements require the assessment of both the velocity distribution and the cross-sectional area of the vessel. Unfortunately several difficulties hamper such a measurement in standard approaches. A new dual beam method has been recently introduced in which the Doppler spectral symmetry is exploited to finely orientating the first beam at 90° with respect to the flow, so th

Anemia, which may develop due to direct effect of the virus or indirect effect of zidovudine a widely used antiviral agent for the treatment, is not an uncommon complication in human immundeficiency virus (HIV) infections. In this report, a 26 years old male HIV positive patient who developed rapid anemia in the HAART (Highly active anti-retroviral therapy) protocol including zidovudine, was prese

What is the origin of HIV as the plaque of our age? What was the way of transmission? Did it just cross from the primates to the human being or has it been introduced accidentally during the polio vaccine trials period in Africa? Is there any other risks in front of the human being, originating from the primates harbouring other viruses. In this review article, it has been tried to give up to date

The first study of this volume looks for reminiscences of Dies Irae in Chopin’s works. A great number of allusions and affinities are found in the preludes as well as in Chopin’s output. The study also yields insights into Chopin’s composition method. These intertextual findings are used in an attempt to establish the extra-musical content of the Second Ballade. Five preludes – A minor, E minor, B

Explorations and analysis of soundscapes have, since Canadian R. Murray Schafer's work during the early 1970's, developed into various established research - and artistic disciplines. The interest in sonic environments is today present within a broad range of contemporary art projects and in architectural design. Aesthetics, psychoacoustics, perception, and cognition are all present in this expand

Energy dispersive extended X-ray absorption fine structure (EDE) has been applied to Pd nanoparticle nucleation at a liquid/liquid interface under control over the interfacial potential and thereby the driving force for nucleation. Preliminary analysis focusing on Pd K edge-step height determination shows that under supersaturated conditions the concentration of Pd near the interface fluctuate ove

The paper focuses on skills and competences applied in audio description (AD) of a Swedish multimodal popular scientific journal. The journal is made accessible for blind and visually impaired audiences by producing an audio version of its verbal and visual contents. The task of the sighted audio describer is to create a verbal description of the contents that activates internal images of the blin
