The discovery of ferroelectricity in hafnium oxide (HfO 2 ) based thin films 2011 renewed the interest ferroelectrics. These new ferroelectrics possess completely different crystal morphology with conventional perovskite ferroelectrics, and present more robust ferroelectric properties upon aggre...

We have previously shown that regulatory T cells (Treg) accumulate dramatically in aged animals and negatively impact the ability to control persistent infection. However, the mechanisms underlying the age-dependent accrual of Treg remain unclear. In this study, we show that Treg accumulation with age is progressive and likely not the result of increased thymic output, increased peripheral prol...

background and aim: today, bilingualism is a developing phenomenon which half of the world population is bilingual. auditory system is the main route to language learning, so it is expected that bilingualism has an effect on functions of the auditory system. auditory memory is one of the auditory processes which is a cornerstone of linguistic skills and learning process growth, so that, it has ...

bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

objectives: the prospective and retrospective memory questionnaire (prmq) developed by smith (2000) and consists of a series of questions about memory weakness that can be encountered anyone in everyday life. the self-reported questionnaire has 16 items that assessing of prospective and retrospective memory problems in everyday life and the aim of the present research was to examine the investi...

The hippocampus and caudate nucleus are anatomical components of relatively independent memory systems and recent research has focused on the nature of the interaction between these two systems. The amygdala exerts a general modulatory influence on memory storage processes related, in part, to an organism's level of affective or emotional arousal. Moreover, affective state can influence the use...
