Research Abstract |
We have studied advanced statistical methods of evaluating brain function for finding risk factors leading malfunctions and diseases with the use of EEG. Our analyses are mainly focused on the nonlinear EEG responses under photo- stimulation and audio- stimulation. The results of our project are summarized as follows : (1) A model of nonlinear responses under the photo- stimulation is constructed ; (2) A new nonlinear model of frequency modulation is proposed with the method for parameter estimation ; (3) The exact solution of a generalized birth-death master equation is obtained ; (4) The heterogeneity of nonlinear response on human scalp is found from photo- stimulated EEG data ; (5) A compact nonlinear model of stream-segregation is proposed.
