introduction: exposure to 3, 4- methylenedioxymethamphetamine (mdma) could lead to serotonergic system toxicity in the brain. this system is responsible for learning and memory functions. studies show that mdma causes memory impairment dose-dependently and acutely. the present study was designed to evaluate the chronic and acute effects of mdmd on spatial memory and acquisition of passive avoid...

Modern neuroscientific research help to solve the impotent challenge in curriculum design and teaching for enhancing students’ ability to organize information in a way that makes it efficient in response to an appropriate context such as problem solving and critical thinking via knowing about the mechanism of different type of memories especially long term memory. At first, we should to c...

autobiographical memory, that is, our memory for personal life experiences, is integral to our sense of self. however, the experience of trauma can create distortions in how our memories are bought to mind. in particular, trauma can produce an overgeneral memory style, which relates to the development of both ptsd and depression. however, theory states that immediately following a traumatic eve...

data with high frequency have a particular type of none stationary that is called fractional none stationary. this property causes the emergence of long-term memory in financial time series with high frequency. the existence of long-term memory in cement industry time-series is studied in this paper at first and its presence will be confirmed in a high confidence level by two tests r/s and gph....

radar transmitters emit high-power radiofrequency radiation by creation of a high-voltage and high-frequency alternating electrical current.health effects of occupational exposure to military radar were investigated. visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. to assess the short-term memory, modified wechsler memory scale test was performe...
