MEMORY AND DEFAULT NETWORK ACTIVATION AS A FUNCTION OF APOE GENOTYPE
… a rest task meant to elicit activity within the Default Network. No differences in memory or metamemory performance were found on the behavioral tasks administered during imaging based on genotype. In contrast, marked differences in brain activation were found between APOE-ε4 carriers and Non …

The Effects of Age and Culture on Default Network Function: Frontal Compensation With Age; Modulation Differences Across Culture
… (East Asian and Western) on the activity of the default network was examined in a memory encoding paradigm. With respect to age, it was theorized that suppression deficits in older adults would be compensated for by enhanced frontal recruitment. With respect to culture, a novel framework was …

The Role of Aerobic Glycolysis in the Resting Human Brain
… activity in the resting state, including the default network and prefrontal cortex, have elevated aerobic glycolysis. In addition, we show that aerobic glycolysis is modulated by prior task performance. Performance of a complex visuomotor rotation learning task increases aerobic glycolysis in …

Separating Component Signals of Episodic Simulation Using a Catch Trial Design
… and that these differences concealed a network of regions sensitive to situations in which information from one’s past is explicitly retrieved.</p>

Cortical Recruitment in Multiple Sclerosis: An fMRI Investigation of Individual Differences
… the functional connectivity of the task-relevant network and the default network in the absence of higher task demands was intact in those with MS. In addition to the study of functional alterations in the presence of MS, I also examined the structural decline in those with MS and its association …

A functional imaging study of the relationship between the Default Mode Network and other control networks in the human brain
The Default Mode Network (DMN) is a large-scale brain network implicated in the control and monitoring of internal modes of cognition. The aim of this research was to investigate DMN function and its relationship to other large-scale cognitive control networks through functional connectivity …

Aging and inhibitory control
… areas in the task evoked visual and attentional networks while younger adults modulate the activity in only a subset of regions. Conversely the younger adults showed a graded level of deactivation across numerous areas of the default network while the older adults did not modulate any regions. A …
