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dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze.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

abstract aim and background: evaluation of cognition is fundamental for every comprehensive epilepsy program. we sought to conduct this study to assess memory state of patients with refractory temporal lobe epilepsy before decision for epilepsy surgery. method and materials: in a case-control study, 20 patients with right temporal lobe epilepsy and 20 patients with left temporal lobe epilepsy w...

This article examines historical transformations of Japanese collective memory of the atomic bombing of Hiroshima by utilizing a theoretical framework that combines a model of reiterated problem solving and a theory of cultural trauma. I illustrate how the event of the nuclear fallout in March 1954 allowed actors to consolidate previously fragmented commemorative practices into a master frame t...

The “cultural turn” in social and humanitarian knowledge has led to the intensive development of various aspects problem collective representations related models forming identity a community. A lot modern research is devoted how people perceive events that they are contemporaries or participants, preserve relay information about these events. process total digitalization society taken place re...

introduction: it has been reported that acute administration of morphine impairs learning and memory processes in rats. furthermore, recent studies showed that saffron extract improved ethanol-induced impairments of learning behaviors in mice, and also prevented ethanol-induced inhibition of hippocampal long-term potentiation. it can be postulated that there are some common mechanisms responsib...

introduction: estrogen is one of the gonadal hormones that has multiple beneficial actions in central nervous system and involves in learning and memory. alzheimer's disease (ad) is a progressive neurodegenerative disorder that impairs patient memory. the human nucleus basalis of meynert (nbm) is severely affected in alzheimer's disease. so in this study the effect of peripheral (intr...

background sildenafil (viagra) has been introduced to treat erectile dysfunction by acting as phosphodiesterase 5 inhibitor and hence accumulation of guanosine cyclic monophosphate (cgmp). on the other hands, the nitric oxide/cgmp signaling pathway has crucial role in synaptic plasticity processes like long-term potentiation (ltp) in the central nervous system considered as a model of learning ...
