My research interest focuses on the analysis of human brain activity. There are two steps to accomplish it: detecting the activity and then investigating the activity.
To detect it, we are not only employing existing techniques, but also developing devices to measure these signals. Two technologies are currently what we are utilizing to detect biological signals from a subject's brain. One is the functional near infrared spectroscopy (fNIRS or diffuse optical imaging). It is to measure concentrations of oxygenated and deoxygenated hemoglobin, because the two chromophores are sensitive to brain's activity. The other technology is the electroencephalography (EEG). It is to detect biophysiological signals, which originate from neuronal activities. The two technologies are not brand new, especially EEG born at 1920s. But there is no such device, which is able to detect both hemodynamic response and biophysiological signals simultaneously and matched spatially. We intended to develop such kind of device, which is necessary to perform studies, such as neurovascular coupling.
To analyze it, we are relying on the inverse problem and graph theory.
