background: this study was planned to examine the effects of whole-body exposure to gsm-950 mhz electromagnetic fields (emfs) on acquisition and consolidation of spatial memory in rats using a water maze task. materials and methods: in experiment 1, the animals were given two blocks of five trials per day for three consecutive days in a water maze task. the interval between blocks was 4h. befor...

MOTIVATION Spatial learning is one of the most widely studied cognitive domains in neuroscience. The Morris water maze and the Barnes maze are the most commonly used techniques to assess spatial learning and memory in rodents. Despite the fact that these tasks are well-validated paradigms for testing spatial learning abilities, manual categorization of performance into behavioral strategies is ...

The present study sought to identify the role of the mammillary bodies and their projections to the anterior thalamic nuclei for spatial memory. Rats with either selective, neurotoxic mammillary body lesions or discrete mammillothalamic tract lesions were tested on various spatial working memory tasks. Tests using the T-maze, radial-arm maze, and water maze were manipulated to compare three pos...

Approximately 50% of New Zealand Black (NZB) mice ectopic NZB mice demonstrated learning impairments in have neocortical ectopias, which are misplaced clusters of the Lashley maze when compared to non-ectopic controls. neurons located in layer I of cortex [17,18]. Previous We used a water version of the Lashley III maze that experiments have found that ectopias in NZB mice were can be learned b...

Four groups of rats were tested on an eight-arm radial maze under a free-choice procedure. The subjects were maintained at either 80% or 100% of their preexperimental free-feeding weights through restricted access to either food or water. Water-deprived subjects received water in the maze; food-deprived subjects received food. Water-deprived subjects learned the task faster than food-deprived s...

Although maternal cigarette smoking during pregnancy is a well-documented risk factor for a variety of adverse pregnancy outcomes, how prenatal cigarette smoke exposure affects postnatal neurobehavioral/cognitive development remains poorly defined. In order to investigate the cause of an altered behavioral phenotype, mice developmentally exposed to a paradigm of 'active' maternal cigarette smok...

lead (pb2+) is a well known neurotoxin that was frequently found in the environment and chronic exposure to lead has been matter of public health. in the present study the effect of lead on spatial memory in developmentally exposed rats and their dams in morris water maze task were investigated. female rats were divided into three groups and two groups exposed to 250 and 750 part per million (p...

BACKGROUND Although ginsenosides such as Rg1, Rb1 and Rg3 have shown promise as potential nutraceuticals for cognitive impairment, their use has been limited due to high production cost and low potency. In particular, the process of extracting pure Rg3 from ginseng is laborious and expensive. METHODS We described the methods in preparing ginseol k-g3, an Rg3-enriched fraction, and evaluated i...

Magnetoreception has been demonstrated in all five vertebrate classes. In rodents, nest building experiments have shown the use of magnetic cues by two families of molerats, Siberian hamsters and C57BL/6 mice. However, assays widely used to study rodent spatial cognition (e.g. water maze, radial arm maze) have failed to provide evidence for the use of magnetic cues. Here we show that C57BL/6 mi...
