Understanding Resting State Functional Connectivity
Resting state functional connectivity is a method used to measure brain networks by observing spontaneous fluctuations in brain activity while a person is at rest. This approach employs an MRI scanner to track blood oxygenation levels without requiring specific tasks from participants, allowing for a more natural representation of brain activity. Researchers have identified approximately 15 to 20 core functional networks within the brain that are present in all individuals, suggesting their foundational role in neurological and psychiatric health. Disruptions in these networks can lead to various disorders, highlighting their significance in understanding brain functionality.
