Learning about cognition risk with the radial-arm maze in the developmental neurotoxicology battery.
Cognitive dysfunction has been found in epidemiological studies to be among the most sensitive impairments associated with developmental exposure to a variety of environmental contaminants from heavy metals to polyhalogenated hydrocarbons and pesticides. These chemicals have been also shown to impair cognitive function after developmental exposure in experimental animal models. The radial-arm m...
The mechanism by which the hippocampus facilitates declarative memory formation appears to involve, among other things, restructuring of the actin cytoskeleton within neuronal dendrites. One protein involved in this process is cortactin, which is an important link between extracellular signaling and cytoskeletal reorganization. In this paper, we demonstrate that total hippocampal cortactin, as ...
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...
Allocentric spatial learning can be assessed using popular spontaneous alternation behaviour (SAB) tested with T-maze, and also using radial arm maze (RAM) tasks. But the SAB testing has been reported to have lack of validity as a measure of retention, especially when used as a measure of short-term memory. A more complex dual alternated task was designed to clarify whether increasing novelty a...
Diospyros mespilliformis (DM) is a plant of the Ebonaceae family that commonly used in traditional medicine to treat epilepsy and schizophrenia. Radial arm mazes (RAM), Y mazes, novel object recognition test (NOR) were assess working reference memory mice. After different tests, hippocampus animals was separated for determination biochemical markers such as acetylcholinesterase (AchE), malondia...
We constructed an 11-arm, walk-through, human radial-arm maze (HRAM) as a translational instrument to compare existing methodology in the areas of rodent and human learning and memory research. The HRAM, utilized here, serves as an intermediary test between the classic rat radial-arm maze (RAM) and standard human neuropsychological and cognitive tests. We show that the HRAM is a useful instrume...
This study examined the effects of disorientation on the acquisition of different spatial reference memory tasks. In an appetitively motivated radial arm maze task in which 1 arm was consistently baited, rats that were disoriented before each trial were impaired in their ability to acquire the task relative to rats placed in a clear container and not disoriented. However, disoriented rats were ...
The limbic thalamus, specifically the anterior thalamic nuclei (ATN), contains brain signals including that of head direction cells, which fire as a function of an animal's directional orientation in an environment. Recent work has suggested that this directional orientation information stemming from the ATN contributes to the generation of hippocampal and parahippocampal spatial representation...
