Past studies show beneficial as well as detrimental effects of subthalamic nucleus deep-brain stimulation on impulsive behaviour. We address this paradox by investigating individuals with Parkinson's disease treated with subthalamic nucleus stimulation (n = 17) and healthy controls without Parkinson's disease (n = 17) on performance in a Simon task. In this reaction time task, conflict between ...

Many years ago Hertwig (1) and Dalcq (2) showed that trypaflavine has the property of inactivating the frog sperm nucleus without affecting the extranuclear parts of the cell. Following an appropriate treatment with the dye, the sperm cells still retain their capacity to activate eggs, but contribute no chromosomes to the resulting embryos, which then develop as haploids with the maternal chrom...

Quantum measurements of physical quantities are often described as ideal measurements. However, only a few fulfil the conditions The aim present work is to describe real position with detectors that able detect single particles. For this purpose, detector model developed can time dependence interaction between non-relativistic particle and detector. example measurement shows be methods quantum ...

Excited states in the neutron-rich nucleus $^{68}\mathrm{Fe}$ were populated using a $^{9}\mathrm{Be}$($^{68}\mathrm{Co}, {}^{68}\mathrm{Fe}+\ensuremath{\gamma})\mathrm{X}$ charge-exchange reaction at 95 MeV/u. The new $\ensuremath{\gamma}$-ray transitions reported here for first time complement data from $\ensuremath{\beta}$-decay studies and nucleon knockout reactions. In comparison to shell-...

Abstract We systematically investigate the relationship between nuclear structure and reaction in 10Be nucleus using a theoretical framework. The of is constructed with cluster model based on microscopic viewpoint. In this paper, prepared different structures by manipulating parameters an effective nucleon–nucleon interaction. expectation values physical quantities are drastically changed modif...

Neurons have complex dendritic trees, receiving numerous inputs at various distances from the cell body. Yet the rules of molecular signal propagation from dendrites to nuclei are unknown. DARPP-32 is a phosphorylation-regulated signalling hub in striatal output neurons. We combine diffusion-reaction modelling and live imaging to investigate cAMP-activated DARPP-32 signalling to the nucleus. Th...

objective: in the present study, we examined the effects of memantine administration within the nucleus accumbens on the alterations in brain and adrenal volumes and weight ratios induced by stress from electric foot shock. methods: a group of mice received various doses of memantine (0.1, 0.5 and 1 mg/kg) prior to induction of stress. another group underwent intra-accumbal cannulation after an...

Mutiple experimental results indicate the existence of cosmophysical effects which influence parameters nuclear decays and chemical reactions in lab. conditions. In particular, variations nucleus alpha-,beta-decay with amplitudes order $10^{-3}$ periods one year solar day were detected. Significant activity on decay reaction also was reported. We argue that such deviations from radioactive law ...
