    Functional magnetic resonance imaging (MRI) is a non-invasive technique for examining brain activity. Resting state fMRI aims to assess spontaneous brain activity using MRI while the participant is at rest, not performing any specific task. It captures ongoing functional connectivity patterns within the brain.
