During the early postnatal age environmental signals underlie development of sensory systems. The visual system is considered as an appropriate system for evaluation of the role of sensory experience in postnatal development of sensory systems. In this study we evaluated the effect of visual deprivation on the usage of visuospatial cues in navigation of radial arm maze. Light (LR) and dark rear...
In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions, visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location. However, the effect depended on the quality of ...
Nitric oxide (NO) is an intercellular messenger that has been suggested to have a role in learning and memory formation. Previous studies with nonselective NO synthase inhibitors have produced contradictory results in learning experiments. However, these drugs also produced blood pressure changes, as NO is an endothelial-derived relaxing factor. A novel NO synthase inhibitor, 7-nitro indazole (...
Background and Objectives: Alzheimer’s disease (AD) is a neurodegenerative disorder characterized clinically by progressive memory loss and subsequent dementia. The aim of this study was to evaluate the synergist effect of folic acid and vitamin B12 on spatial memory in adult male rat Alzheimer's disease. Material and methods: In this experimental study, 49 male Wistar rats were randomly...
