Background & Aims: Diabetes mellitus is a chronic metabolic disorder that in the long-term is accompanied with deficits in learning, memory, and cognitive skills. Due to the existing evidence regarding the anti-diabetic potential of acetyl-L-carnitine (ALC), the effect of its long-term administration on learning and spatial memory deficits was investigated in diabetic rats. Methods: In this exp...
there are many discrepancies around the effect of sex hormones on spatial learning and memory in rodents. the aim of the present study was to investigate the effects of chronic administration of estradiol (es) and testosterone (tes) on spatial memory in adult castrated male rats. cholinesterase activity of the hippocampus in treated animals was also measured to seek if hormonal treatment can ch...
Background: The effect of ovariectomy and accompanying sudden loss of circulating gonad hormones on spatial learning performance in the young adult rats was examined. We hypothesized that spatial learning and memory in a considerable number of women who undergo a surgical menopause and estrogen deprivation before their natural menopause be impaired. Methods: In this study, we used 26 Wistar ra...
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
Background: Multiple sclerosis (MS ( is one of the chronic autoimmune diseases of the central nervous system with unknown etiology. Nitric oxide (NO) as a free radical has contradictory effect on the central nervous system and on MS disease. Nitric oxide is one of the distractive factors of the immune system and is a factor in the destruction of myelin. On the other hand, there is an interact...
Introduction: Primary stress can impair the nervous structure including the hippocampus and behavioral functions such as memory; therefore, paying attention to neutralizing the destructive effects of stress on the body has been one of the debatable topics among researchers. Considering the role of physical activity in reducing stress in previous studies, this study aimed to investigate the effe...
Introduction: Maternal separation (MS) can lead to learning and memory deficits, and also the risk of addiction. On the other hand, physical activities may lead to long-term changes in the mesolimbic dopamine pathway and the hippocampus. This study was designed to examine the effect of swimming exercise on the spatial learning and memory and voluntary morphine consumption in maternally separate...
in recent years, the effects of exercise on nervous system, spatial memory andmotor function in the senescence period have received the attention of researchers.as the age increases, some functions of nervous system such as spatial memory areweakened. thus, the effect of aerobic exercises including swimming and runningon learning, spatial memory and motor function was investigated in old rats. ...
background: sporadic alzheimer’s disease (sad) is caused by genetic risk factors, aging and oxidative stresses. the herbal extract of rosa canina (r. canina), tanacetum vulgare (t. vulgare) and urtica dioica (u. dioica) has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. in this study, the neuroprotective effects of this herbal extract in the rat model of sad was i...
nitric oxide (no) is thought to be involved in spatial learning and memory in several brain areas such as hippocampus. this study examined the effects of post-training intrahippocampal microinjections of 1400w as a selective inos inhibitor on spatial memory, in anesthetized and non-anesthetized situations in rats. in the present work, 4-day training trials of animals were conducted. spatial mem...
