Task-independent and task-specific age effects on brain activity during working memory, visual attention and episodic retrieval.
It is controversial whether the effects of aging on various cognitive functions have the same common cause or several different causes. To investigate this issue, we scanned younger and older adultsExpand
Brain Activity during Episodic Retrieval of Autobiographical and Laboratory Events: An fMRI Study using a Novel Photo Paradigm
Functional neuroimaging studies of episodic memory retrieval generally measure brain activity while participants remember items encountered in the laboratory (controlled laboratory condition) orExpand
Effects of aging on the neural correlates of successful item and source memory encoding.
To investigate the neural basis of age-related source memory (SM) deficits, young and older adults were scanned with fMRI while encoding faces, scenes, and face-scene pairs. Successful encodingExpand
When less means more: deactivations during encoding that predict subsequent memory
TLDR
In event-related functional MRI (fMRI) studies, greater activity for items that are subsequently remembered (R-items) than for items That are subsequently forgotten (F-items), or Dm effect (Difference in memory), has been attributed to successful encoding operations. Expand
Neural Correlates of Relational Memory: Successful Encoding and Retrieval of Semantic and Perceptual Associations
Using event-related functional magnetic resonance imaging, we identified brain regions involved in successful relational memory (RM) during encoding and retrieval for semantic and perceptualExpand
Posterior Midline and Ventral Parietal Activity is Associated with Retrieval Success and Encoding Failure
The ventral part of lateral posterior parietal cortex (VPC) and the posterior midline region (PMR), including the posterior cingulate cortex and precuneus, tend to show deactivation during demandingExpand
Frontiers in Human Neuroscience
The ventral part of lateral posterior parietal cortex (VPC) and the posterior midline region (PMR), including the posterior cingulate cortex and precuneus, tend to show deactivation during demandingExpand
Cortical deactivation in mild cognitive impairment: high-field-strength functional MR imaging.
PURPOSE To prospectively identify brain regions in which task-related changes in activation during a memory encoding task, measured with functional magnetic resonance (MR) imaging, correlate withExpand
Default mode network connectivity in stable vs progressive mild cognitive impairment
Objective: Dysfunction of the default mode network (DMN) has been identified in prior cross-sectional fMRI studies of Alzheimer disease (AD) and mild cognitive impairment (MCI); however, no studiesExpand
Prognostic Value of Posteromedial Cortex Deactivation in Mild Cognitive Impairment
Background Normal subjects deactivate specific brain regions, notably the posteromedial cortex (PMC), during many tasks. Recent cross-sectional functional magnetic resonance imaging (fMRI) dataExpand
