the effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولDoxepin improves stress-impaired long-term potentiation and gene expression of BDNF in the rat hippocampus
Introduction: Stress is associated with neurological and cognitive disorders. It has been suggested that doxepin, in addition to its influence on the content of neurotransmitters, has probable neuroprotective effects as well. Therefore, the aim of this study was to investigate the effects of doxepin on synaptic plasticity and brain-derived neurotrophic factor (BDNF) gene expression in the rat h...
متن کاملEffect of forced treadmill exercise on long-term potentiation (LTP) in the dentate gyrus of hippocampus in male rats
Introduction: Previous studies indicate that exercise influences cognitive function. Nevertheless, considering that exercise in animal study can be voluntary, or forced, effects of exercise (specially forced exercise) on learning and memory abides as a matter of controversy. The present study aimed to investigate the effects of treadmill exercise on LTP in the dentate gyrus of rats. Methods: T...
متن کاملKappa opioids inhibit induction of long-term potentiation in the dentate gyrus of the guinea pig hippocampus.
NMDA receptor-mediated long-term potentiation (LTP) of dentate granule cell responses to perforant path stimulation was inhibited by the kappa 1 opioid receptor agonist U69,593. This inhibition was reversed stereospecifically by naloxone and blocked by the selective kappa 1 antagonist norbinaltorphimine (NBNI). NBNI, by itself, had no effect on LTP induced by threshold stimulation but significa...
متن کاملdose dependent effect of memantine on long-term potentiation in the ca1 area of the hippocampus
introduction: generally, nmda receptor antagonists inhibit learning and long-term potentiation (ltp). however, it has been suggested that direct tonic activation of nmda receptors, in contrast to learning, may lead to an increase in synaptic “noise”. uncompetitive nmda receptor antagonist memantine can paradoxically reverse deficits in learning and synaptic plasticity, and restore ltp impaired ...
