Research
Our laboratory focuses on the mapping of human brain function using Magnetic Resonance Imaging (MRI), known as Functional MRI or fMRI, and other technologies, such as Near Infrared Spectroscopy (NIRS) and Transcranial Magnetic Stimulation (TMS). In fMRI, we develop technology for improved acquisition, making it faster, more quantitative, or with fewer distortions. We also seek to understand and model the physiological changes (cerebral metabolism, blood flow, volume or oxygenation) in response to task activation so that the signals we detect can be appropriately calibrated. Lastly, we seek to apply our technology to new application domains in collaboration with basic and clinical neuroscientists across campus.
(a) In response to the working memory task, corresponding parts of the subject's brain are activated.
(b) Shows activation of the subject's visual cortex when presented with a stimulus in the form of a fashing checkerboard.
