Background: Diabetes mellitus affects numerous intracellular metabolic processes, which are reflected by changes in the concentration of some plasma constituents. Particularly, the disease may indirectly undermine some functions of the nervous system including learning and memory through altering oxidative stress status. On the other hand, probiotics can enhance the antioxidant capacity. This s...
Background: The hippocampus, a vital center for learning and memory, is extremely vulnerable to neurological diseases.Several reports of cognitive and memory impairment have been published in patients with Multiple sclerosis (MS). The prevalence of MS is highest where environmental supply of vitamin D is low. In the present study spatial working memory and reference memory after treatment with ...
Ascorbic acid (AA) as a vitamin and neuromodulator is present in most parts of CNS such as nucleus accumbens shell (Acbsh). This study evaluates the effect of intra-nucleus accumbens shell injection of AA on spatial learning and memory. 35 adult male Wistar rats (220-270 g) were divided into 5 groups: control (intact), sham AA (injected normal saline as AA vehicle) as well as 3 groups of AA (12...
hippocampus is essentially involved in learning and memory processes, and is known to be a target for androgen actions. the high density of the androgen receptors in hippocampus shows that there must be some relationship between androgens and memory. androgen effects on spatial memory are complex and contradictory. some evidence suggests a positive correlation between androgens and spatial memo...
CA1 region of hippocampus has an important role in learning and memory. Previous reports have shown that androgens like testosterone and its metabolites are present in high concentration in CA1 region of hippocampus. Androgen receptors have also high density in this region. Therefore, it is suggested that neurohormones in CA1 have an important role in learning and memory. It is likely that...
diabetes mellitus is associated with distribution of cognitive functioning. hyperglycemia diabetes mellitus is associated with distribution of cognitive functioning. hyperglycemia induced oxidative stress has been proposed as a cause of memory complications of diabetes including cognitive impairment. the aim of this study was to examine total green tea extract (tgte), a potent free radical scav...
objective(s) the possible risks of radio-frequency electromagnetic fields (emf) for the living organisms and human body are a growing concern for our society. in this study, we examined the possibility of changes in working memory and hippocampal histological characteristics effects in mice brain following whole body exposure to microwave radiation. materials and methods during gestation period...
It has been shown that brain glucose metabolism impairment, obesity, and diabetes couldlead to cognitive decline and Alzheimer’s disease (AD) pathogenesis. Kisspeptin (KP) a G-proteincoupled receptor neuropeptide, has been suggested as a link between energy balance andreproduction. Some studies have shown that the attenuation of KP signaling decreases metabolismand energ...
Background and Aim: Memory and learning are the putative targets for the stressors by some biochemical reactions such as glucocorticoid hormones. Intermittent feeding is a kind of dietary behavior with some reported positive efficacy on the various systems of the body. The aim of this study was the evaluation of intermittent feeding on learning and spatial memory in the male mice under chronic ...
objective: this study was designed to examine the effect of environmental enrichment during methamphetamine (meth) dependency and withdrawal on methamphetamine-induced spatial learning and memory deficits and obsessive-compulsive behavior. method: adult male wistar rats (200 ± 10 g) chronically received bi-daily doses of meth (2 mg/kg, sc, with 12 hours intervals) for 14 days. rats reared in st...
