زمینه و هدف : در هیپوکامپ اصلی علاوه بر نورون های هرمی، آستروسیت ها نیز نقش بسیار مهمی را در تبادلات یونی، رهائی نوروترانسمیترها و حتی حافظه ایفا می کنند. حافظه و یادگیری مفاهیم بسیار نزدیکی هستند. در واقع آموزش نیازمند برخی امکانات برای ذخیره اطلاعات و مکانیسم های نگهداری اطلاعات شبیه به حافظه است. هدف ما از این مطالعه تعیین تاثیر آموزش فضائی روی تعداد آستروسیت های هیپوکامپ موش صحرائی بود. روش...

a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Background: The hippocampus, a vital center for learning and memory, is extremely vulnerable to neurological diseases.Several reports of cognitive and memory impairment have been published in patients with Multiple sclerosis (MS). The prevalence of MS is highest where environmental supply of vitamin D is low. In the present study spatial working memory and reference memory after treatment with ...
this research aimed to review the use of second-person reference in advertisement translation, work out the general rules, and provide guidance to translators. using second-person reference is common in the advertising discourse. addressing audiences directly involves their attention and in this way enhances their memorization of the advertised message. second-person reference can be realized v...
objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...
The Basolateral Amygdala (BLA) has modulatory effects on working and reference memory. The aim of this study was the evaluation of effects of dopaminergic system in the BLA of rats on working and reference memory behaviors. The number of working and reference errors and time spent in the arms by rats were measured in the radial arm maze according to DSWS protocol. The animals were cannulated in...
objective(s) the possible risks of radio-frequency electromagnetic fields (emf) for the living organisms and human body are a growing concern for our society. in this study, we examined the possibility of changes in working memory and hippocampal histological characteristics effects in mice brain following whole body exposure to microwave radiation. materials and methods during gestation period...
During a critical period of postnatal age sensory experience has a profound effect on maturation of visual cortical wiring. Electrophysiological evidence is indicating a substantial effect of visual deprivation on the visual cortical response properties. In this study we evaluated effect of light deprivation during a limited time of postnatal age on two aspects of spatial (working and reference...
