fMRI (functional Magnetic Resonance Imaging)

fMRI, or functional Magnetic Resonance Imaging, is a medical imaging technique that measures brain activity by detecting changes in blood flow. When a specific brain area is active, it requires more oxygen, leading to increased blood flow to that region. The fMRI scanner captures these changes by monitoring oxygen levels in the blood, allowing researchers and doctors to see which parts of the brain are involved in different tasks or processes in real-time. This non-invasive method helps in understanding brain function, diagnosing conditions, and planning treatments.
