Alterations in default network connectivity in posttraumatic stress disorder related to early-life trauma.
BACKGROUND The "default network" consists of a number of brain regions that exhibit correlated low-frequency activity at rest and that have been suggested to be involved in the processing ofExpand

Spontaneous low-frequency fluctuations in the BOLD signal in schizophrenic patients: anomalies in the default network.
Spontaneous low-frequency fluctuations in the blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (MRI) signal have been shown to reflect neural synchrony between brain regions.Expand

Default mode network connectivity: effects of age, sex, and analytic approach
The ‘default mode network’ is a set of brain regions showing correlated, low-frequency activity during rest. It includes the posterior cingulate/precuneus, medial prefrontal cortex, and bilateralExpand
