the aim of the present study was to investigate whether and by which mechanism; histamine can induce state-dependent retrieval of passive avoidance task. the pre-training or pre-test intracerebroventricular (i.c.v.) injection of histamine (20µg/mouse) impaired retrieval, when it was tested 24 h later. in the animals, which retrieval was impaired due to histamine pre-training administration, pre...
reconsolidation memory is defined as a process in which the retrieval of a previously consolidated memory returns to a labile state which is then subject to stabilization. previous studies have shown that mineralocorticoid receptors (mrs) modulate distinct phases of learning and memory, which display a high concentration and distinct distribution in the hippocampus. moreover, we found no studie...
background: the spice zingiber officinale or ginger possesses antioxidant activity and neuroprotective effects. in this study we hypothesized that treatment with hydroethanolic extract of ginger (50, 100 and 200 mg/kg, p.o) would effect on the hyoscine-induced memory impairment in rats. methods: in this experimental study 64 male wistar rats were divided into eight groups (8 rats in each group)...
Background and Objective: Cannabinoids are a class of psychoactive compounds that produce a wide array of effects in a large number of species. In the present study, the effects of bilateral intra-CA1 injections of L-arginine on WIN55, 212-2 induced state-dependent memory of passive avoidance task was examined in mice. Materials and Methods: One-trial step-down paradigm was used for the assessm...
objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...
Background and Objective: Memory naturally degrades with the passing of time. Dementia or deficit of memory caused by Alzheimer’s disease, aging and other risk factors, greatly affects one’s day-to-day life. Lavandula officinalis is an effective medicinal plant in treating inflammation, epilepsy, depression and anxiety. Also, recently have been submitted reports about the effects of lavender on...
Introduction: Studies have proposed that royal jelly(RJ) has various biological activities in different cells and tissues. Since it has been demonstrated that RJ contains compounds having desirable effects on central neurons system and neural functions, the present study aimed to investigate the effect of royal jelly on learning and memory in rats. Methods: Male wistar rats were divided into t...
Considerable evidence indicates that the basolateral complex of the amygdala (BLA) interacts with efferent brain regions in mediating glucocorticoid effects on memory consolidation. Here, we investigated whether glucocorticoid influences on the consolidation of memory for emotionally arousing training depend on functional interactions between the BLA and the medial prefrontal cortex (mPFC), a b...
Objective(s): Diabetes mellitus (DM) is a widespread metabolic disorder worldwide. Clinical physicians have found diabetic patients have mild to middle cognitive dysfunction and an alteration of brain monoaminergic function. This study explored the change in various patterns of behavioral models and brain monoamine function under streptozotocin (STZ)-induced type 1 diabetes.Materials and Method...
Background and purpose: The quality of life in patients with cancer is affected by cognitive changes after chemotherapy. There are different reports about the effect of cyclophosphamide as a chemotherapy agent on cognitive function. So, the present study aimed to investigate the effects of acute and chronic injections of cyclophosphamide on passive avoidance and novel object recognition memory ...
