摘要
Technology of brain–computer interface(BCI)provides a new way of communication and control without language or physical action.Brain signal tracking and positioning is the basis of BCI research,while brain modeling affects the treatment analysis of(EEG)and functional magnetic resonance imaging(fMRI)directly.This paper proposes human ellipsoid brain modeling method.Then,we use non-parametric spectral estimation method of time–frequency analysis to deal with simulation and real EEG of epilepsy patients,which utilizes both the high spatial and the high time resolution to improve the doctor’s diagnostic efficiency.
