background: brain is the most important organ as it controls and co- ordinates all the activities of our body. reports on neuroethological investigations in mice particularly associated with learning and memory after radiation exposure are very scanty. hence, present investigation is an attempt to examine the effects of low dose tritiated water (hto) acute exposure on adult swiss albino mice in...
objective: walnut (juglans regia) is a domestic fruit of iran. walnut kernel (wk) has many beneficial constituents such as unsaturated fatty acids, antioxidants, and vitamin e. scientific studies have shown that fatty acids and vitamin e can modulate learning and memory processes. the aim of the present work was to study effects of walnut consumption by mothers during pregnancy and lactation on...
objective(s) learning is defined as the acquisition of information and skills, while subsequent retention of that information is called memory. the objective of the present study was to investigate the effect of aqueous extract of boswellia papyrifera on learning and memory paradigms in mice and rats. materials and methods this study was held at the department of pharmacology, faculty of pharma...
background sildenafil (viagra) has been introduced to treat erectile dysfunction by acting as phosphodiesterase 5 inhibitor and hence accumulation of guanosine cyclic monophosphate (cgmp). on the other hands, the nitric oxide/cgmp signaling pathway has crucial role in synaptic plasticity processes like long-term potentiation (ltp) in the central nervous system considered as a model of learning ...
objective: the nucleus accumbens (nac) receive histaminergic neurons from tuberomammillary nuclei. there are reports indicating that central histamine systems are involved in many physiological behavioral processes, including anxiety. the aim of the present study was to assess whether the histaminergic system of the nac is involved in anxiety-related behaviors. methods: rats were anesthet...
background: through its membrane and intracellular receptors, vitamin d regulates many vital functions in the body including its well known actions on musculoskeletal system. growing body of evidences demonstrate that vitamin d undergoes some of behavioral aspects of neurocognition. the present study was designed to evaluate the effect of food regimens without vitamin d or with a supplement of ...
introduction: the role of ovarian hormones and nitric oxide (no) on oxidative damage in brain tissues as well as learning and memory has been widely investigated.the present study was carried out to evaluate the effect of the precursor of no, l-arginine on learning and brain damage due to oxidative stress in ovariectomized (ovx) rats.methods: thirty -two rats were divided into four groups: 1) s...
Introduction: Synaptic plasticity has been suggested as the primary physiological mechanism underlying memory formation. Many experimental approaches have been used to investigate whether the mechanisms underlying long-term potentiation (LTP) are activated during learning. Nevertheless, little evidence states that hippocampal-dependent learning triggers synaptic plasticity. In this study, we in...
This research provides an overview of the historical advances of the maze tests that are widely used to assess the cognitive impairments in rodents. Particularly, this study focuses on the issue of learning and memory behavioral tests, including dry and water mazes. Several types of mazes have been used in this setting, but their real advantages and applications depend on the type selected by t...
background and objective: based on the effect of chronic metabolic diseases including diabetes mellitus on the learning and memory, this study was designed to assess the usefulness of administration of salvialonic acid b on lessening of learning and memory deficits in streptozotocin (stz)-diabetic rats. materials and methods: male wistar rats were allocated into control, salvialonic acid b-trea...
