background and aims: the spice zingiber officinale or ginger possesses antioxidant and neuroprotective effects. in this study we hypothesized that treatment with hydroethanolic extract of ginger (50, 100 and 200 mg/kg, p.o) would have an effect on the scopolamine-induced memory impairment in rats.methods: in this experimental study, 64 male wistar rats were divided into eight groups (8 rats in ...

objectives: this study examined the relationship between working and short-term memory performance, and their effects on cochlear implant outcomes (speech perception and speech production) in cochlear implanted children aged 7-13 years. the study also compared the memory performance of cochlear implanted children with their normal hearing peers. methods: thirty-one cochlear implanted children w...

there is strong evidence that two cerebral hemispheres are differentially involved in emotional memory and that amygdala is a key subcortical structure for emotional experience. the present research investigated the possible involvement of lateralization of basolateral amygdala (bla) and central amygdala (cea) in place avoidance memory. for this purpose, male long-evans rats (280-320 g) were im...

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...

introduction: ascorbic acid (aa) acts as an antioxidant in the central nervous system (cns) of the mammalians. it is released from the some nerve ending together with neurotransmitters. the results have shown that ascorbic acid could affect learning as well as memory. in this study, we examined the effect of icv injection of ascorbic acid on learning and memory by morris water maze. method: in ...

introduction: intracerebroventricular (i.c.v.) injection of streptozotocin (stz) to rodents has been reported as an appropriate model for sporadic dementia of alzheimer's type (sdat), characterized by a progressive impairment of memory. however, very little or nothing is known about non-cognitive behavioral effects in the stz model. this study was carried out in order to show the protectiv...

nowadays, it is common to find optimal point of the dynamic problem; dynamic problems whose optimal point changes over time require algorithms which dynamically adapt the search space instability. in the most of them, the exploitation of some information from the past allows to quickly adapt after an environmental change (some optimal points change). this is the idea underlining the use of memo...

purpose our study aimed to profile the effect of fasting during the ramadan month on cognitive function in a group of healthy muslim athletes. methods eighteen male athletes underwent computerized neuropsychological testing during (fasting) and after (non-fasting) ramadan. diet was standardized, and tests were performed at 0900h and 1600h to characterize potential time-of-day (tod) interactions...
