Abnormal Brain Default-Mode Network Functional Connectivity in Drug Addicts
BACKGROUND The default mode network (DMN) is a set of brain regions that exhibit synchronized low frequency oscillations at resting-state, and is believed to be relevant to attention and self-monitoring. As the anterior cingulate cortex and hippocampus are impaired in drug addiction and meanwhile are parts of the DMN, the present study examined addiction-related alteration of functional connect...
متن کاملDynamic Default Mode Network across Different Brain States
The default mode network (DMN) is a complex dynamic network that is critical for understanding cognitive function. However, whether dynamic topological reconfiguration of the DMN occurs across different brain states, and whether this potential reorganization is associated with prior learning or experience is unclear. To better understand the temporally changing topology of the DMN, we investiga...
متن کاملDefault Mode Network Connectivity in Stroke Patients
The pathophysiology of episodic memory dysfunction after infarction is not completely understood. It has been suggested that infarctions located anywhere in the brain can induce widespread effects causing disruption of functional networks of the cortical regions. The default mode network, which includes the medial temporal lobe, is a functional network that is associated with episodic memory pr...
متن کاملDefault mode network connectivity during task execution
Initially described as task-induced deactivations during goal-directed paradigms of high attentional load, the unresolved functionality of default mode regions has long been assumed to interfere with task performance. However, recent evidence suggests a potential default mode network involvement in fulfilling cognitive demands. We tested this hypothesis in a finger opposition paradigm with task...
متن کاملThe effects of task context and brain injury on default mode network brain functional connectivity
INRODUCTION The default mode network (DMN) has been a major area of research in recent years. Studies have sought to determine the exact nature of its activity and how these profiles of neural activity respond to cognitive demands or are abnormal in pathological conditions [e.g. 1-3]. Activity within the network has been correlated with rest and anti-correlated with task performance [4]. As suc...
