background: cyclooxygenase (cox) enzyme known as a regulatory factor in synaptic plasticity. it has been reported that synaptic plasticity is one of the mechanisms involved in learning and memory processes. in the current study peripheral injection's effects of sodium salicylate (as a non selective cox inhibitor) on spatial learning and memory have been investigated. methods: four groups of mal...

many previous studies used leader - member exchange to explain the quality relationship between employees and supervisors. however, in previous studies, the mechanism of this theory in creativity is not so clear. thus, this study defines the role of leaders in creating a culture of organizational learning using normative approach to examine the relationship between communication quality leader ...

alzheimer's disease (ad) is the most prevalent neurodegenerative disorder. it is characterized by formation of amyloid plaques and neurofibrillary tangles in the brain, degeneration of the cholinergic neurons and neural cell death. this study was aimed to investigate the effect of a triazine derivative, c16h12cl2n3s, on learning in an alzheimer's rat model. animals were divided into seven group...

In regard to the role of Aluminium in the emergence of psychological disorded in patients with chronic kidney diseases,this research project studied the acute,and chronic effects of Alluminium on different stages of memory and learning abilitis,after grouping the rats Alluminium chloride with concentrations of 1mg,5mg,10mg and 20 mg was used per kg of body weight.the Alluminium was given by int...

Education is a dynamic and continuous process and requires the knowledge and learning of the most basic human needs. These needs created due to the changes that occur with increasing age in the learning system of the elderly people, are more evident at old age. It is important to select the appropriate educational method for learning in this age group. Hence, this review study investigates the ...

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...

increased level of stress has negative effects on cognitive functions. thus, it is necessary to identify appropriate strategies to prevent cognitive and motor performance decline. the aim of this research was to study the effect of immobilization stress on learning and memory and the protective role of physical activity in them. from male albino-wistar rats of pastor institute, 32 rats were ran...
