resting state fMRI
Resting-state fMRI (functional magnetic resonance imaging) is a brain imaging technique that measures brain activity while a person is at rest, not performing any specific tasks. It detects changes in blood flow, which reflect neural activity, allowing researchers to observe how different brain regions communicate with each other. By analyzing these patterns, scientists can identify networks within the brain that are involved in various functions and understand how they might relate to behaviors or mental health conditions. This technique helps in mapping the brain's functional architecture in a non-invasive way.

Resting state fMRI (functional magnetic resonance imaging) is a brain imaging technique that measures brain activity when a person is not performing any specific task—essentially when they are at rest. It detects changes in blood flow and oxygen levels in different brain regions, revealing how these areas communicate with each other. This helps researchers understand the brain's functional architecture and connectivity, providing insights into normal brain functions, as well as disorders such as Alzheimer's or depression, by highlighting patterns of connectivity that may be disrupted.
