Age-related memory decline has been associated with a faulty regulation of the hypothalamus-pituitary-adrenal axis (HPA-axis). The aim of this study was to investigate whether the magnitude of the stress-induced cortisol increase is related to memory performance when memory is measured in non-stressful conditions. To do so, declarative and working memory performance were measured in 31 men and ...

Substantial evidence suggests that human category learning is governed by the interaction of multiple qualitatively distinct neural systems. In this view, procedural memory is used to learn stimulus-response associations, and declarative memory is used to apply explicit rules and test hypotheses about category membership. However, much less is known about the interaction between these systems: ...

197 IT IS BECOMING INCREASINGLY CLEAR THAT NREM SLEEP, ESPECIALLY SLOW WAVE SLEEP (SWS), IS IMPORTANT FOR THE PROCESSING OF HIPPOCAMPUSdependent declarative memories,1-6 with SWS hypothesized to provide the optimal electrophysiological and biochemical state for this type of processing.7,8 When sleep occurs in the form of a short daytime nap, it is very common to obtain only NREM sleep, without ...

Abstract Runtime systems can significantly reduce the cognitive complexity of scientific applications, narrowing gap between engineering and domain science in HPC. One most important angles this is automating data migration a cluster. Traditional approaches require application developer to model communication explicitly, for example through MPI primitives. Celerity, runtime system accelerator c...
