Functional MRI, or Functional Magnetic Resonance Imaging, is a new examination method for studying human brain function that can show minute changes in the brain with high temporal and spatial resolution, and is primarily used in neuroscience. Functional MRI is an emerging neuroimaging modality based on the principle of using magnetic resonance imaging to measure hemodynamic changes triggered by neuronal activity. Functional magnetic resonance imaging is a new examination method to study the function of the human brain with non-invasive, high temporal and spatial resolution, and is gradually applied in many fields of neuroscience to elucidate the higher neurophysiology, neuropsychological activity modalities, and functional connections between the cerebral cortex. Functional MRI, as a non-destructive and dynamic detection technology, has increasingly become an important method for observing brain activity and thus revealing the relationship between the brain and the mind.
