The human brain is intrinsically organized into dynamic, anticorrelated functional networks.
We investigate the extent to which this task-related dichotomy is represented intrinsically in the resting human brain through examination of spontaneous fluctuations in the functional MRI blood oxygen level-dependent signal. Expand

Control of goal-directed and stimulus-driven attention in the brain
We review evidence for partially segregated networks of brain areas that carry out different attentional functions. One system, which includes parts of the intraparietal cortex and superior frontalExpand

The Reorienting System of the Human Brain: From Environment to Theory of Mind
Survival can depend on the ability to change a current course of action to respond to potentially advantageous or threatening stimuli. This "reorienting" response involves the coordinated action of aExpand

Electrophysiological signatures of resting state networks in the human brain
Functional neuroimaging and electrophysiological studies have documented a dynamic baseline of intrinsic (not stimulus- or task-evoked) brain activity during resting wakefulness. This baseline isExpand

Voluntary orienting is dissociated from target detection in human posterior parietal cortex
Human ability to attend to visual stimuli based on their spatial locations requires the parietal cortex. One hypothesis maintains that parietal cortex controls the voluntary orienting of attentionExpand

The Human Connectome Project: A data acquisition perspective
The Human Connectome Project (HCP) is an ambitious 5-year effort to characterize brain connectivity and function and their variability in healthy adults using multiple imaging modalities along with extensive behavioral and genetic data. Expand

Common Blood Flow Changes across Visual Tasks: II. Decreases in Cerebral Cortex
Nine previous positron emission tomography (PET) studies of human visual information processing were reanalyzed to determine the consistency across experiments of blood flow decreases during activeExpand

Spontaneous neuronal activity distinguishes human dorsal and ventral attention systems.
On the basis of task-related imaging studies in normal human subjects, it has been suggested that two attention systems exist in the human brain: a bilateral dorsal attention system involved inExpand

Large-scale cortical correlation structure of spontaneous oscillatory activity
Little is known about the brain-wide correlation of electrophysiological signals. We found that spontaneous oscillatory neuronal activity exhibited frequency-specific spatial correlation structure inExpand

Breakdown of Functional Connectivity in Frontoparietal Networks Underlies Behavioral Deficits in Spatial Neglect
Spatial neglect is a syndrome following stroke manifesting attentional deficits in perceiving and responding to stimuli in the contralesional field. We examined brain network integrity in patientsExpand
