Summary of "The prestimulus default mode network state predicts cognitive task performance levels on a mental rotation task."

Linking individual task performance to preceding, regional brain activation is an ongoing goal of neuroscientific research. Recently, it could be shown that the activation and connectivity within large-scale brain networks prior to task onset influence performance levels. More specifically, prestimulus default mode network (DMN) effects have been linked to performance levels in sensory near-threshold tasks, as well as cognitive tasks. However, it still remains uncertain how the DMN state preceding cognitive tasks affects performance levels when the period between task trials is long and flexible, allowing participants to engage in different cognitive states.

Alterations of the default mode network and cognitive impairment in patients with unilateral chronic tinnitus.

Previous studies have demonstrated that cognitive impairment is linked with neurophysiological alterations in chronic tinnitus. This study aimed to investigate the intrinsic functional connectivity (F...

Role of the Default Mode Network in Cognitive Transitions.

A frequently repeated finding is that the default mode network (DMN) shows activation decreases during externally focused tasks. This finding has led to an emphasis in DMN research on internally focus...

Exploring distinct default mode and semantic networks using a systematic ICA approach.

Resting-state networks (RSNs; groups of regions consistently co-activated without an explicit task) are hugely influential in modern brain research. Despite this popularity, the link between specific ...

Aberrant Default Mode Network Underlying the Cognitive Deficits in the Patients With Late-Onset Depression.

Late-onset depression (LOD) is regarded as a risk factor or a prodrome of Alzheimer's disease (AD). Moreover, LOD patients with cognitive deficits have the higher risk of subsequent AD. Thus, it is ne...

Functional connectivity of intrinsic cognitive networks during resting state and task performance in preadolescent children.

Earlier studies on adults have shown that functional connectivity (FC) of brain networks can vary depending on the brain state and cognitive challenge. Network connectivity has been investigated quite...

Medical and Biotech [MESH] Definitions

The observation and analysis of movements in a task with an emphasis on the amount of time required to perform the task.

Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.

A psychological state of awareness, the practices that promote this awareness, a mode of processing information and a character trait. As a therapy mindfulness is defined as a moment-to-moment awareness of one's experience without judgment and as a state and not a trait.

A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.

Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.
