Resting State Networks
Resting State Networks (RSNs) are groups of brain regions that show synchronized activity when a person is not focused on a specific task. These networks are identified using functional magnetic resonance imaging (fMRI) and are thought to reflect the brain's intrinsic connectivity. Common RSNs include the default mode network, which is active during daydreaming and self-referential thought.
Research on RSNs helps scientists understand how the brain organizes itself and communicates internally. By studying these networks, researchers can gain insights into various conditions, such as Alzheimer's disease and autism, where typical brain connectivity may be disrupted.
