  • This book is about how to construct and use computational models of specific parts of the nervous system, such as a neuron, a part of a neuron or a network of neurons. It is designed to be read by people from a wide range of backgrounds from the biological, physical and computational sciences. The word ‘model’ can mean different things in different disciplines, and even researchers in the same field may disagree on the nuances of its meaning.

  • NADPH-dependent dual-flavin enzymes provide electrons in many redox reactions, although the mechanism responsible for regulating their electron flux remains unclear. We recently proposed a four-state kinetic model that links the electron flux through a dual-flavin enzyme to its rates of interfla

  • In view of the dynamic growth in the luxury market and the availability of luxury goods to a wider range of consumers than ever before, the luxury market has transformed from its traditional conspicuous consumption model to a new experiential luxury sensibility marked by a change in the way consumers define luxury. In a global context, it is critically important for luxury researchers and marketers to understand why consumers buy luxury, what they believe luxury is and how their perception of luxury value impacts their buying behavior.

  • Abstract Although gait change is considered a useful indicator of severity in animal models of Parkinson's disease, systematic and extensive gait analysis in animal models of neurological deficits is not well established. The CatWalk-assisted automated gait analysis system provides a comprehensive way to assess a number of dynamic and static gait parameters simultaneously. In this study, we used the Catwalk system to investigate changes in gait parameters in adult rats with unilateral 6-OHDA-induced lesions and the...

  • Recent re-analyses of time series studies have highlighted a second important epidemiological and statistical issue known as confounding bias. Pollution relative rate estimates for mortality= morbidity could be confounded by observed and unobserved time-varying confounders (such as weather variables, season, and in°uenza epidemics) that vary in a similar manner as the air pol- lution and mortality=morbidity time series. To control for confounding bias, smooth functions of time and temperature variables are included into the semi-parametric Poisson regression model....

  • It is our pleasure to present the Proceedings of the 16th International Congress on Parkinson’s Disease (PD) and Related Disorders (16th ICPD) which took place in Berlin from June 5–9, 2005. This congress was the most successful congress ever with more than 3500 participants in the roaring German capital, consisting of an innovative program and with emphasis on bringing basic and clinical scientists together. Special attention has was paid in inviting young scientists.

  • The extracellular signal regulated protein kinases (ERK1/2) are essential for normal development and functional plasti-city of the central nervous system. However, a growing number of recent studies in models of cerebral ischemia, brain trauma and neurodegenerative diseases implicate a detrimental role for ERK1/2 signaling during oxidative neuronal injury. Neurons undergoing oxidative stress-rela-ted injuries typically display a biphasic or sustained pattern of ERK1/2 activation.

  • Recent and increasing use of computational tools in the field of nicotinic receptors has led to the publication of several models of ligand–receptor interactions. Thesemodels are all basedon the crystal structure at 2.7 A˚ resolutionof aprotein related to the extracellular N-terminus of nicotinic acetyl-choline receptors (nAChRs), the acetylcholine binding pro-tein. In the absence of any X-ray or NMR information on nAChRs, this new structure has provided a reliable alter-native to study the nAChR structure....

These results over whole classes of machines are very difficult to obtain, and none el any significance exist for parsiD.g problems.

  • At the time of Isaac Newton’s invention of the calculus in the 17th century, the mechanical clock was the most sophisticated machine known. The simplicity of the clock allowed its movements to be completely described with mathematics. Newton not only described the clock’s movements with mathematics, but also the movements of the planets and other astronomical bodies. Because of the success of the Newtonian method, a mathematics-based model of reality resulted.

  • The purpose of The Handbook of Neuroprosthetic Methods is threefold. First, the book combines the most commonly employed concepts, applications, and knowledge from the many disciplines associated with neuroprosthetic research in a clear and instructive way. Second, the book provides examples of neuroprosthetic systems at different stages of development, from the more mature cochlear implant to the maturing areas of upper-limb and motor control to the relatively fledgling area of visual prostheses.

  • Motor neuron degeneration in amyotrophic lateral sclerosis involves oxida-tive damage. Glutathione (GSH) is critical as an antioxidant and a redox modulator. We used a motor neuronal cell line (NSC-34) to investigate whether wild-type and familial amyotrophic lateral sclerosis-linked G93A mutant Cu,Zn superoxide dismutase (wt⁄G93ASOD1) modified the GSH pool and glutamate cysteine ligase (GCL), the rate-limiting enzyme for GSH synthesis.

  • An emerging body of evidence supports a key role for the endocannabinoid system in numerous physiological and pathological mechanisms of the cen-tral nervous system. In the recent past, many experimental studies have examined the putative protective or toxic effects of drugs interacting with cannabinoid receptors or have measured the brain levels of endocannabi-noids inin vitro and in vivo models of cerebral ischemia.

The etiology of PD is probably a combination of environmental and genetic factors.
