Resting-state Networks in Dementia

The use of functional magnetic resonance imaging in task-free situations (i.e., resting state fMRI) has gained great popularity in clinical neuroscience over the last ten years. In this setup, patients' brains are scanned at rest, and the brain signals can then be separated into distinct networks of synchronous activity. The default network (DN) is one frequently studied network that shows abnormalities over a range of psychiatric and neurodegenerative disorders, including schizophrenia, autism, and Alzheimer's disease. The DN consists of parietal and frontal midline structures that have been linked to explicit…
