bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...
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...
Introduction: Cognitive impairment rate such as memory loss increases because of aging as a natural process. Based on the evidence, physical activity can lead to improved mental and cognitive function and also plays a preventive role against reducing cognitive function. the purpose of this study was to investigate the effect of yoga exercises on memory of elderly women. Methods: This experime...
objectives: the prospective and retrospective memory questionnaire (prmq) developed by smith (2000) and consists of a series of questions about memory weakness that can be encountered anyone in everyday life. the self-reported questionnaire has 16 items that assessing of prospective and retrospective memory problems in everyday life and the aim of the present research was to examine the investi...
This study investigated whether application of acute restraint stress or dexamethasone, as a glucocorticoid receptor agonist, impaired retrieval of long-term memory and if pretreatment with opiate antagonist naloxone blocked their effects on memory retrieval. Young adult male rats were trained in one trial inhibitory avoidance task (1 mA, 1.5 s foot shock). On retention test given 48 hr after t...

Introduction: Zinc is an essential rare element that plays an important role in synaptic plasticity and modulation of the activity of central nervous system and is involved in learning and memory. Increasing zinc intake may protect against conditions associated with zinc deficiency, such as diabetes. Some studies have revealed that zinc deficiency in diabetic subjects is due to hogher excret...
Consumers’ prior experiences shape an episodic memory which largely influences their decision-making process. This episodic memory is mainly linked to cognitive and emotional perception and we know that a brand image influences our cognitive and emotional perception. Nevertheless, it has not been well described how autobiographical memories of brand images differ from those of other types of im...
Objective(s) Cyclooxygenases (COXs) are known to play some roles in physiological mechanisms related to learning and memory. Since sodium salicylate is an inhibitor of COX, we have evaluated the effect of peripheral and intra-hippocampal administration of sodium salicylate on spatial learning and memory in male rats. Materials and Methods Male rats were studied in two groups; the first grou...
