The Morris water maze (MWM) is a commonly used apparatus for measuring visuo-spatial reference or working memory in rodents. In the reference memory task in our lab, mice are trained to locate a submerged platform in a circular pool filled with opaque water by using distal extra-maze visual cues. Learning in the MWM is typically assessed with measures of performance including latency and distan...

This study determined whether developmental and adult 3,4-methylenedioxymethamphetamine (MDMA) exposures in rats have interactive effects on body temperature, learning, other behaviors, and monoamine concentrations in the hippocampus, prefrontal cortex, and striatum. Learning was assessed in the Cincinnati water maze (CWM), Morris water maze (MWM), and novel object recognition (NOR). On acquisi...

The present study was designed to evaluate the neuroprotective effect of Erythropoietin (EPO) in brain of memory impaired mice. Memory impairment was produced by THP in different groups of animals. Morris water maze (MWM) and Elevated plus maze (EPM) test was employed to assess learning and memory. At the end of study brain anticholinesterase (AchE) activity was estimated. Administration of EPO...

Following bilateral lesions targeting lateral deep cerebellar nuclei, rats were subjected to a bridge test as a measure of visuomotor coordination and were trained on the Morris water maze (MWM) as a measure of visuospatial processing. Lesioned rats were significantly impaired in visuospatial processing, but not visuomotor coordination, relative to sham rats. In a 2nd experiment, rats were pret...

Introduction: In the recent years, the use of several drugs such as cocaine and morphine has reduced, but the use of "club drugs" has increased in many countries. 3, 4-methylenedioxymethamphetamine (MDMA) which has known as ‘ecstasy’ among people has many harmful effects on serotonergic system in the brain. This system is responsible for learning and memory. In this study, we tested sub-acute a...

Learning and memory as well as long-term potentiation (LTP) depend on Ca (2+) influx through the NMDA-type glutamate receptor (NMDAR) and the resulting activation of the Ca (2+) and calmodulin-dependent protein kinase (CaMKII). Ca (2+) influx via the NMDAR triggers CaMKII binding to the NMDAR for enhanced CaMKII accumulation at post-synaptic sites that experience heightened activity as occurrin...

Morris water maze (MWM) test is widely used to evaluate the learning and memory deficits in rodents. Image processing pattern recognition can be analyse videos recognize automatically tracking MWM. There are several commercial free access software that allows analyzing behavioral tasks although they also have limitations such as automation, cost, user intervention among other things. The aim of...

The Morris water maze (MWM) is one of the most common tasks used to assess spatial learning and memory ability in rodents. Genetic strain and gender are two prominent variants that influence spatial performance. Although it was reported that ICR (Institute of Cancer Research) mice exhibited an unchanged baseline performance in the training phase of the MWM task, this outbred strain has been wid...

INTRODUCTION The Alzheimer Disease (AD) is the most common form of dementia that leads to memory impairment. As the oxidative stress plays an important role in AD pathogenesis, the current study aimed at examining the protective effects of Cyperus Rotundus as an antioxidant on amyloid β (Aβ)-induced memory impairment. METHODS Twenty-eight Wistar male rats received intrahippocampal (IHP) injec...
