Striatal Contributions to Declarative Memory Retrieval
Declarative memory is known to depend on the medial temporal lobe memory system. Recently, there has been renewed focus on the relationship between the basal ganglia and declarative memory, including the involvement of striatum. However, the contribution of striatum to declarative memory retrieval remains unknown. Here, we review neuroimaging and neuropsychological evidence for the involvement ...
متن کاملStress enhances reconsolidation of declarative memory.
Retrieval of negative emotional memories is often accompanied by the experience of stress. Upon retrieval, a memory trace can temporarily return into a labile state, where it is vulnerable to change. An unresolved question is whether post-retrieval stress may affect the strength of declarative memory in humans by modulating the reconsolidation process. Here, we tested in two experiments whether...
متن کاملThe role of memory in posttraumatic stress disorder: A review of memory impairments and memory-based theories
Post-traumatic stress disorder (PTSD) is a psychiatric syndrome caused by exposure to threatening events such as war, car accidents, and physical and sexual assault. The experience of psychological trauma can have long-term cognitive effects. The symptoms of PTSD include changes in cognitive processes such as memory, attention, planning, and problem-solving and destructive effects on a person's...
متن کاملAcute stress does not affect the impairing effect of chronic stress on memory retrieval
Objective(s): Due to the prevalence and pervasiveness of stress in modern life and exposure to both chronic and acute stresses, it is not clear whether prior exposure to chronic stress can influence the impairing effects of acute stress on memory retrieval. This issue was tested in this study. Materials and Methods: Adult male Wistar rats were randomly assigned to the following groups: control,...
متن کاملChaotic Genetic Algorithm based on Explicit Memory with a new Strategy for Updating and Retrieval of Memory in Dynamic Environments
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...
