introduction: working memory is thought to serve as a part of memory structure where functions like temporary storage and manipulation of information take place. this study investigates the effectiveness of working memory training regimens with iranian university students, while considering the implications for medical students. methods: thirty university students studying at different universi...

there are several conflicting evidences showing the effect of morphine on learning and memory processes. in the present study the effect of chronic morphine administration on passive avoidance, active avoidance and spatial learning and memory of morphine dependent male rats using passive avoidance shuttle box and morris water maze tasks were investigated, respectively. male rats received morphi...

objective: memory and concentration may be affected by hemodialysis in end-stage renal disease. in this study, changes in cognitive function parameters such as attention, impulsiveness, and reaction time were measured and evaluated in the iranian hemodialysing patients. methods: in this analytic observational study, cognitive function of 38 hemodialysis patients was measured before and after he...

background:purpose of present study was to investigate whether chronic exposure to zinc fume would affect serum zinc levels, memory, and cognition in zinc fume-exposed workers. methods:in a cross-sectional study, all zinc fume-exposed workers (exposed, n=20) were compared with unexposed workers (reference, n=20) matched for sex and education level in a zinc galvanization factory. the workers we...

the multiple sclerosis (ms) is a chronic disease of cns leads to some dysfunctions including cognitive (working memory), mood (depression) and fatigue. in spite of previous investigations about working memory impairment in patients with ms, there are scare evidences for working memory dysfunction in mild disabled ms patients (edss

introduction: in the present study, the effect of an inducible no synthase (inos) inhibitor, aminoguanidine (ag) on lipopolysaccharide (lps)-induced memory impairment and oxidative stress and inflammation parameters was evaluated. materials and methods: the rats were divided into 5 groups and treated: 1) control (saline), 2) lps (1 mg/kg), 3-5) ag 50, 100 and 150mg/kg 30 min before lps injectio...

objective: working memory is the ability of maintaining and manipulating the required information for operating generalization in future. the aim of the present research is to investigate the effectiveness of neurofeedback therapy on the working memory in children with adhd.  methods: 24 children with adhd who had the required standards to participate in the study were selected by accessible sa...

introduction: exposure to 3, 4- methylenedioxymethamphetamine (mdma) could lead to serotonergic system toxicity in the brain. this system is responsible for learning and memory functions. studies show that mdma causes memory impairment dose-dependently and acutely. the present study was designed to evaluate the chronic and acute effects of mdmd on spatial memory and acquisition of passive avoid...

conclusions ferulago angulata extract, because of its antioxidant activities, is probably capable of removing free radicals and oxidant substances from brain and thus it can improve behavioral disorders in brain hypoperfusion ischemia model. results it was found that the administration of 400 mg/kg hydroalcoholic extract of f. angulate for two weeks after brain hypoperfusion ischemia increased ...

  Numerous studies conducted in laboratory animals and humans indicate that angiotensin converting enzyme inhibitors reinforce memory and learning. In this paper we study the effect of injection of enalapril into the cerebral ventricles on spatial memory of white mice in the double- y maze, following the induction of an Alzheimer- like amnestic model with scopolamine. To estimate the duration o...
