Activity and reactivity of the default mode network in the brain was studied using functional
magnetic resonance imaging (fMRI) in 28 nondemented individuals with mild cognitive …

Recent functional imaging studies have revealed coactivation in a distributed network of
cortical regions that characterizes the resting state, or default mode, of the human brain …

Using resting state (RS) functional magnetic resonance imaging (fMRI), the connectivity
patterns of the default mode (DMN), frontoparietal, executive, and salience networks were …

Alzheimer's disease (AD) is the most common form of dementia in old age, and is
characterized by prominent impairment of episodic memory. Recent functional imaging …

Age-related effects on the default mode network (DMN) connectivity as measured at rest
using functional magnetic resonance imaging (fMRI) are now well described. Little is known …

Amnestic mild cognitive impairment (aMCI) is a syndrome associated with faster memory
decline than normal aging and frequently represents the prodromal phase of Alzheimer's …

In the past decade, a “default mode network”(DMN) has been highlighted in neuroimaging
studies as a set of brain regions showing increased activity in task‐free state compared to …

Resting-state functional magnetic resonance imaging (MRI), have revealed coactivation in a
distributed network that characterizes the default-mode in the human brain. However, details …

Resting-state networks dissociate in the early stage of Alzheimer's disease (AD). The
posterior cingulate cortex (PCC) in AD brain is vulnerable to isolation from the rest of brain …

We applied a multi-modal imaging approach to examine structural and functional alterations
in the default-mode network (DMN) that are associated with Alzheimer's disease (AD) and …
