introduction: previous studies have demonstrated that the &beta-adrenergic; receptor antagonist propranolol impairs fear memory reconsolidation in experimental animals. there are experimental parameters such as the age and the strength of memory that can interact with pharmacological manipulations of memory reconsolidation. in this study, we investigated the ability of the age and the strength ...

introduction: estrogen is one of the gonadal hormones that has multiple beneficial actions in central nervous system and involves in learning and memory. alzheimer's disease (ad) is a progressive neurodegenerative disorder that impairs patient memory. the human nucleus basalis of meynert (nbm) is severely affected in alzheimer's disease. so in this study the effect of peripheral (intr...

background lead poisoning impairs memory and learning. objectives the protective effect of natural zeolite clinoptilolite on memory and learning impairment in rats exposed to lead acetate was investigated. materials and methods 60 male wistar rats in six groups treated for 2 months with diets contained different ratios of natural zeolite(i.e. 5% or 12.5%), and %0.2 lead acetate (la) concentrati...

objective(s) we determined the effect of a high fructose diet either alone or in combination with iranian shallot or garlic extract on cognitive functions, plasma lipid profile, and the intraperitoneal glucose tolerance test (ipgtt). materials and methods following induction of insulin resistance in fructose-fed rats (fru-fed), they were randomly assigned to three subgroups. the first subgroup ...

background: this study assessed the relationship between working memory capacity and auditory stream segregation by using the concurrent minimum audible angle in children with a diagnosed auditory processing disorder (apd). methods: the participants in this cross-sectional, comparative study were 20 typically developing children and 15 children with a diagnosed apd (age, 9–11 years) according t...

introduction: the present post-eventual research study was conducted with the purpose of comparing the memory performance between two distinct groups of 50 healthy children and 50 attention deficit hyperactivity disorder (adhd) children (25 girls and 25 boys) in tehran with an age range of 10-12. methods: the whole students were selected through simple random sampling method and were assessed i...

introduction: recent studies suggest that glucocorticoids modulate memory reconsolidation. moreover, cholinergic system is involved in memory reconsolidation. since glucocorticoids interact with brain cholinergic system in modulating memory processing, we investigated whether glucocorticoid influences on the reconsolidation of emotionally arousing training depend on the cholinergic system. meth...

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...
