Understanding neural network dysfunction in neurodegenerative disease is imperative to
effectively develop network-modulating therapies. In Alzheimer's disease (AD), cognitive …

Individuals diagnosed with mild cognitive impairment (MCI) are at high risk of transition to
Alzheimer's disease (AD). However, little is known about functional characteristics of the …

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 …

By detecting spontaneous low-frequency fluctuations (LFF) of blood oxygen level–
dependent (BOLD) signals, resting-state functional magnetic resonance imaging (rfMRI) …

Cortical functional connectivity, as indicated by the concurrent spontaneous activity of
spatially segregated regions, is being studied increasingly because it may determine the …

Altered oscillatory brain activity in Alzheimer disease (AD) may reflect underlying
neuropathological changes, and its characterization might lead to new diagnostic …

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 …

Objective: To investigate the relation between atrophy of the hippocampal region and brain
functional patterns during episodic memory processing in Alzheimer's disease. Patients and …

Functional MRI (fMRI) in established Alzheimer's disease (AD) shows regionally altered
blood oxygenation level dependent (BOLD) responses. Mild cognitive impairment (MCI) is …

There has been a dramatic increase in the number of studies using resting state functional
magnetic resonance imaging (rs-fMRI), a recent addition to imaging analysis techniques …
