Functional MRI (fMRI): Lying inside the MRI scanner, the participant performs a cognitive task while her brain images are continuously taken. By applying computational analysis on the images, brain regions that were utilized in the task can be identified. The figure illustrates the brain regions "activated" when the person looks at a scene picture displayed on a computer screen.
Dr. Lu's research interest is to use magnetic resonance imaging (MRI) technologies to study physiology and metabolism of the human brain, and to use this information for understanding how the brain functions and how clinical diagnosis of brain disorders can be improved. In particular, the focus of his research program is the measurement of cerebral blood flow, cerebral blood volume, blood oxygenation level, and cerebral metabolic rate of oxygen using advanced MRI techniques.
