Background: Numerous evidences indicate that various environmental stresses during pregnancy affect physiological behavior of the offspring. This experimental study was designed to investigate the effect of noise stress during prenatal period of rats on spatial learning and memory and plasma corticostrone level in postnatal life.Methods: Three groups of pregnant rats were given daily noise ...
Interaction of Intrahippocampal Injection of Naltheroxone and Corticosterone on Consolidation and Retreival Memory Processes in Passive Avoidance Task in Rat AA. Vafaei [1] , A. Rashidy-Pour [2] Received: 15/01/08 Sent for Revision: 01/07/08 Received Revised Manuscript: 15/09/08 Accepted: 20/10/08 Background and Objectives Previous studies suggested that the role of corticostero...
Background and Objective: Psychosocial stresses are one of the causes of most clinical problemes of general health of societies. It can produce and intensify many diseases such as cardiovascular disorders. Studeise have shown this type of stress could produce free radicales and lead to oxidative stress. As regular exercise is effective in decreasing mortality from cardiovasulare dieases, immobi...
Background : Chronic Cerebral Hypoperfusion (CCH) is a common pathophysiological state that generally happens in conditions such as Alzheimer and vascular dementia, which both of them are known by cognitive impairment. The recognition of particular mechanisms in the chain of events from CCH to a cognitive deficit may identify potential targets for efficient therapies. The purpose of t...
Background: It is believed that cognitive processing is easily disturbed by incompatible environmental stimulations. Many studies have shown that prenatal stress affects fetal brain development. The aim of this study was to evaluate the effect of noise pollution exposure during conception period on neural activity of hippocampus CA1 area in male rat offspring. Methods: Four groups of rats inclu...
due to the increasing presence of electromagnetic radiation in advanced societies, investigation of the effects of this radiation on humans has attracted the interest of many researchers. the non- ionizing radiation can induce numerous effects through biomolecules in the tissue and cells. in the current study, effects of 12 hz electromagnetic waves investigated on neuronal hormone levels in rat...
Introduction: Previous studies demonstrated that forced and voluntary exercise had ameliorative effects on behavioral tasks followed by Sleep Deprivation (SD) in intact female rats. The main goal of this research was evaluating the impact of voluntary exercise on cognitive functions while SD and ovariectomization is induced in female wistar rats. Methods: The rats were anesthesized combining d...
objective: strong evidence indicate that activity of glucocorticoid receptors is necessary for emotional memory processess and these effects probably are mediated by hipppocampal opioid receptors. the aim of this study was to test whether there were any interaction between glucocorticoid and hippocampal opiate receptors on consolidtaion and retrieval of spatial memory. materials and methods: in...
Background and Objectives: So far the effectiveness of high-intensity interval training on learning and memory has remained unknown. Therefore, we aimed to investigate the effect of high intensity interval training on hippocampal corticosterone levels and passive avoidance memory in male rats. Materials and Methods: In this experimental study, 40 male Wistar rats were placed into 5 groups (n...
