Introduction: Alzheimer’s disease (AD) is an age-related neurodegenerative disease, which impairs memory and cognitive function. Walnuts are a dietary source of polyphenols, antioxidants and other compounds with health beneficial effects. These characteristic of walnuts make them perfect candidates for evaluation of their possible effects on neurodegenerative diseases. Therefore the prese...

Background & objectives: Mitochondrial dysfunction is one of the main risk factors for neurological diseases which are associated with aging. On the other hand, aerobic exercise has beneficial effects on the brain health and cognitive function, and also improves mitochondrial dynamics. Therefore, the aim of the present study was to investigate the effect of 4 weeks of aerobic exercise on spatia...

abstract   introduction: diabetes mellitus accompanies with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. considering the beneficial antidiabetic potential of nigella sativum (ns ), this research study was conducted to evaluate the effect of chronic consumption of ns on learning and memory in diabetic rats using passive avoidance and y-maz...

Abstract: ِIntroduction: The effect of morphine dependency on learning and spatial memory is controversial. So in this study effect of co-administeration of nitric oxide (NO) and morphine in CA3 of hippocampus on learning and spatial memory in morphine dependent rats was investigated. Methods: After anaesthetization of male rats, cannulae implanted bilaterally in CA3 of hippocampus. After reco...

Introduction: Cognitive impairment is commonly associated with pain. The modulatory role of orexin 1 receptor (OX1R) in pain pathways as well as learning and memory processes is reported in several studies. The current study was designed to investigate the possible role of CA1-hippocampal OX1R on spatial learning and memory of rats following capsaicin-induced orofacial pain. Methods: Orofacial...

introduction: the cholinergic system plays an important role in learning and memory. administration of either extracts of crocus sativus (saffron) or its constituent, crocin, reduced ethanol-induced memory impairment. based on the above findings, we investigated the effect of crocin in antagonizing spatial learning and memory impairment induced by scopolamine, a cholinergic receptor antagonist,...

Thisstudy sought to evaluate the learners' achievements with the visual learning style when exposed to the sentence making and word list approaches. On that account, 45 basic level participants who studied at the Iran Language Institute (ILI), Bushehr, took part in this research study. At the outset, the learners were given Barsch learning style inventory (1991) to determine the learners' learn...

morphine’s effects on learning and memory processes are well known to depend on synaptic plasticity in the hippocampus. whereas the role of the hippocampus in morphine-induced amnesia and state-dependent learning is established, the biochemical and molecular mechanisms underlying these processes are poorly understood. the present study intended to investigate whether administration of morphine ...

Introduction: Aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. Aluminum ions in the brain cause serious problems such as Alzheimer, Parkinson and other degenerative diseases. On the other hand, Zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates wi...
