Resting-state functional connectivity is a powerful tool for studying human functional brain
networks. Temporal fluctuations in functional connectivity, ie, dynamic functional connectivity …

The human brain is a complex dynamic system capable of generating a multitude of
oscillatory waves in support of brain function. Using fMRI, we examined the amplitude of …

Multimodal evidence suggests that brain regions accumulate information over timescales
that vary according to anatomical hierarchy. Thus, these experimentally defined “temporal …

Purpose To investigate alterations in functional connectivity in the resting brain networks in
healthy elderly volunteers and patients with mild, moderate, or severe Alzheimer Disease …

Synchronized low‐frequency BOLD fluctuations are observed in dissociable large‐scale,
distributed networks with functional specialization. Two such networks, referred to as the …

Abstract Spontaneous infra-slow (< 0.1 Hz) fluctuations in functional magnetic resonance
imaging (fMRI) signals are temporally correlated within large-scale functional brain …

Knowledge about the intrinsic functional architecture of the human brain has been greatly
expanded by the extensive use of resting-state functional magnetic resonance imaging …

Functional imaging studies have shown reduced activity within the default mode network
during attention-demanding tasks. The network circuitry underlying this suppression remains …

The development of highly accelerated fMRI acquisition techniques has led to novel
possibilities to monitor cerebral activity non-invasively and with unprecedented temporal …

Modulation of brain state, eg, by anesthesia, alters the correlation structure of spontaneous
activity, especially in the delta band. This effect has largely been attributed to the∼ 1 Hz …
