    內容簡介:Full brain EEG and its source localization is a brain imaging modality based on multi-channel Electroencephalography (EEG) signals. It measures the brain field potential fluctuations on the entire scalp for a period of time, and then we mathematically calculate the electric current density inside the brain by solving an inverse Poisson problem at each time. The time trajectories of EEG signal on the scalp and inside the brain reveal brain dynamics at rest or during brain cognitions. In this talk, we introduce mathematical methods for the EEG source reconstruction problems and discuss its methodology and applications. One application is in identifying abnormality in brain activities during seizures of an infant patient with Glucose Transporter Deficiency Syndrome. Another application is to find the neuronal signatures in response to pain stimulations. Further work shows these data can be further used to study the brain network properties that glean into the inner working of brain functions.
