Default Network and Aging: Beyond the Task-Negative Perspective.
نویسندگان
چکیده
During cognitive tasks requiring externally directed attention, activation in the default-network (DN) typically decreases below baseline levels ('deactivation'). Healthy aging is associated with reduced deactivation, which is usually attributed to a failure to suppress DN processes. Recent evidence instead suggests that older adults may be more reliant on DN than young adults when performing these tasks.

Integration of the Existed Knowledge on DMN: A Critical Review Study
The default-mode network (DMN) is one of the human brain’s networks activated in resting and self-referential thinking states. The nature of this network and its normal or abnormal changes has been the subject of various studies. The aim of this study was to systematical review and integrating the findings of that studies focused on the relationship of DMN with mental disorders and aging-induce...
متن کاملAttenuated anticorrelation between the default and dorsal attention networks with aging: evidence from task and rest.
Anticorrelation between the default and dorsal attention networks is a central feature of human functional brain organization. Hallmarks of aging include impaired default network modulation and declining medial temporal lobe (MTL) function. However, it remains unclear if this anticorrelation is preserved into older adulthood during task performance, or how this is related to the intrinsic archi...
متن کاملPrefrontal Engagement and Reduced Default Network Suppression Co-occur and Are Dynamically Coupled in Older Adults: The Default-Executive Coupling Hypothesis of Aging
Reduced executive control is a hallmark of neurocognitive aging. Poor modulation of lateral pFC activity in the context of increasing task challenge in old adults and a "failure to deactivate" the default network during cognitive control tasks have been observed. Whether these two patterns represent discrete mechanisms of neurocognitive aging or interact into older adulthood remains unknown. We...
متن کاملPutting age-related task activation into large-scale brain networks: A meta-analysis of 114 fMRI studies on healthy aging
Normal aging is associated with cognitive decline and underlying brain dysfunction. Previous studies concentrated less on brain network changes at a systems level. Our goal was to examine these age-related changes of fMRI-derived activation with a common network parcellation of the human brain function, offering a systems-neuroscience perspective of healthy aging. We conducted a series of meta-...
متن کاملAn Application of Genetic Network Programming Model for Pricing of Basket Default Swaps (BDS)
The credit derivatives market has experienced remarkable growth over the past decade. As such, there is a growing interest in tools for pricing of the most prominent credit derivative, the credit default swap (CDS). In this paper, we propose a heuristic algorithm for pricing of basket default swaps (BDS). For this purpose, genetic network programming (GNP), which is one of the recent evolutiona...
