Memory and learning are considered as the most complicated and important processes of behavioral sciences. On the other hand, considering the wide .and progressively increasing applications of anesthetic agents all over the world, it is of great importance to have a reasonable knowledge regarding their effects on the memory process and its retrieval. The main purpose of this study was to evalua...

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dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze.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 ...

many factors are involved in learning and memory processes including brain nuclei, neurotransmitter systems, and the activity of ion channels. studies showed inconsistent effects of calcium channel blockers on learning process, especially memory consolidation; however, little is known about their effect on memory acquisition and retrieval. accordingly, the present study aimed to determine the e...

feedback training can lead to large and significant changes in alpha densities when conditions have lowered alpha density below the levels seen spontaneously under optimal conditions. Subjects can acquire volitional control over alpha activity only under conditions which normally lead to decreased densities. Thus, during the initial orientation in the dark, when subjects experiment, but are not...

Demand for high-speed dynamic reconfiguration of a programmable device is increasing for raising the performance level of such devices. To support high-speed dynamic reconfiguration, optically reconfigurable gate arrays (ORGAs) have been developed. An ORGA consists of a holographic memory, a laser array, and an optically reconfigurable gate array VLSI. The holographic memory can store many conf...

introduction: the brain renin-angiotensin system (ras) has been reported having a pathological role in age-related impairment in learning and memory. therefore, angiotensin converting enzyme inhibitors (acei) are expected to have positive effects on memory. longtime treatment with captopril (an angiotensin converting enzyme inhibitor) significantly attenuates the age-related impairment in learn...

Many of the problems considered in optimization and learning assume that solutions exist in a dynamic. Hence, algorithms are required that dynamically adapt with the problem’s conditions and search new conditions. Mostly, utilization of information from the past allows to quickly adapting changes after. This is the idea underlining the use of memory in this field, what involves key design issue...

objective: children with attention deficit hyperactivity disorder (adhd) do not process most information due to inattention and loss of the opportunity to save and retrieve information. therefore, these children experience memory impairment. although visual memory has been previously studied in children with adhd, iconic memory in these children has been less evaluated. we aimed to study the po...

experiences indicate that after earthquakes a little attention is paid to the role of collective memory (cm) in the reconstruction process. this is due to time constraints, because all organizations try to speed up the physical reconstruction process, after the disasters. thus, quality is sacrificed for quantity. herein one of the most challenging issues is the reconstruction of bazaar neighbor...
