The Barnes maze is one of the main behavioral tasks used to study spatial learning and memory. The Barnes maze is a task conducted on "dry land" in which animals try to escape from a brightly lit exposed circular open arena to a small dark escape box located under one of several holes at the periphery of the arena. In comparison with another classical spatial learning and memory task, the Morri...

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 Pha...

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...

the present study was undertaken to investigate the beneficial effects of widely-prescribed lipid lowering drugs, pitavastatin, atorvastatin and simvastatin 3-hydroxy-3-methylglutaryl-coenzyme-a (hmg-coa) reductase inhibitors in cognitive dysfunctions of mice. intra-cerebroventricular (icv)-streptozocin-(stz)- and high-fat diet (hfd)-induced amnesia served as interoceptive memory models where a...

The role of lateral septal vasopressin (VP) in the modulation of spatial memory, social memory, and anxiety-related behavior was studied in adult, male Wistar rats. Animals were equipped with osmotic minipumps delivering the VP-antagonist d(CH2)5-D-Tyr(Et)VAVP (1 ng/0.5 microl per h) bilaterally into the lateral septum (LS). Subsequently, all rats were subjected to four behavioral tests. First,...

introduction: ascorbic acid (aa) acts as an antioxidant in the central nervous system (cns) of the mammalians. it is released from the some nerve ending together with neurotransmitters. the results have shown that ascorbic acid could affect learning as well as memory. in this study, we examined the effect of icv injection of ascorbic acid on learning and memory by morris water maze. method: in ...

there are several conflicting evidences showing the effect of morphine on learning and memory processes. in the present study the effect of chronic morphine administration on passive avoidance, active avoidance and spatial learning and memory of morphine dependent male rats using passive avoidance shuttle box and morris water maze tasks were investigated, respectively. male rats received morphi...

sporadic alzheimer’s disease (sad) is affected by genetic risk factors, aging and oxidative stresses. the herbal extract of r. canina, t. vulgare and u. dioica has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. we investigate the neuroprotective effects of this herbal extract in the rat model of sad.  the rats were divided into control, sham, model, herbal extract...
