diabetes mellitus is associated with disturbances of learning and memory and cognitive functioning. aegle marmelos corr. from rutaceae family, is widely used in iranian folk medicine for the treatment of diabetes mellitus. it decreases blood glucose level by improving glucose tolerance and also has lipid-lowering and antioxidant properties. considering the beneficial antidiabetic potential of a...

the purpose of this study was twofold: (a) to assess the retention of two word types (synonyms and homonyms) in the short term memory, and (b) to investigate the effect of these word types on word learning by asking learners to learn their persian meanings. a total of 73 iranian language learners studying english translation participated in the study. for the first purpose, 36 freshmen from an ...

the hippocampal system plays an important role in memory function. neurohormones like androgens and estrogens that syntheses in hippocampus have an important role in learning and memory. many biological effects of estrogens in the brain via estrogenic receptors (ers) are investigated. the current research has conducted to assess the effect of estrogenic receptors on spatial discrimination in ra...

conclusions the role of exercise is greater in the retention than the acquisition phase for recalling past experiences. background stress induced by sleep deprivation can cause degradation of learning in the acquisition phase, and low-intensity exercise can prevent the negative effects of stress. results the results showed that, after seven days of aerobic exercise on a treadmill, the experimen...

electroconvulsive therapy (ect) is an efficient treatment for several neuropsychiatric disorders however a large number of patients develop memory impairment after ect. different studies both on animals and human suggest that vasopressin has positive effects on memory and improves cognitive functions. in this randomized, double-blind controlled clinical trial, 50 patients with psychiatric disor...

introduction: there are evidences showing the role of nitric oxide in the opiate reward properties. the role of nitric oxide signaling pathway as an intracellular mechanism on augmentation of long term potentiation in hippocampal ca1 area of rats is also confirmed. it has been also reported that oral morphine dependence facilitates formation of spatial learning and memory via activation of nmda...

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: th...

introduction: it has been reported that acute administration of morphine impairs learning and memory processes in rats. furthermore, recent studies showed that saffron extract improved ethanol-induced impairments of learning behaviors in mice, and also prevented ethanol-induced inhibition of hippocampal long-term potentiation. it can be postulated that there are some common mechanisms responsib...
