Our brain is a network. It consists of spatially distributed, but functionally linked regions that
continuously share information with each other. Interestingly, recent advances in the …

The majority of functional neuroscience studies have focused on the brain's response to a
task or stimulus. However, the brain is very active even in the absence of explicit input or …

Spontaneous fluctuations are a hallmark of recordings of neural signals, emergent over time
scales spanning milliseconds and tens of minutes. However, investigations of intrinsic brain …

Neural connections, providing the substrate for functional networks, exist whether or not they
are functionally active at any given moment. However, it is not known to what extent brain …

Resting-state functional magnetic resonance imaging (fMRI) has attracted more and more
attention because of its effectiveness, simplicity and non-invasiveness in exploration of the …

During performance of attention-demanding cognitive tasks, certain regions of the brain
routinely increase activity, whereas others routinely decrease activity. In this study, we …

Variations in neural circuitry, inherited or acquired, may underlie important individual
differences in thought, feeling, and action patterns. Here, we used task-free connectivity …

Functional MRI (fMRI) can be applied to study the functional connectivity of the human brain.
It has been suggested that fluctuations in the blood oxygenation level-dependent (BOLD) …

Resting state functional MRI (fMRI) has enabled description of group-level functional brain
organization at multiple spatial scales. However, cross-subject averaging may obscure …

Resting state functional connectivity MRI (fcMRI) is widely used to investigate brain networks
that exhibit correlated fluctuations. While fcMRI does not provide direct measurement of …
