Phase estimation of visual evoked responses.
The phase of visual evoked responses (VERs) is one of the basic parameters in functional diagnostics of the visual system. A new method for phase estimation of VERs based on the observer model in system identification is introduced. Simulated data show significantly less variance of estimation than actual estimators do. By means of the new estimator, the dynamics of the visual system according to selected optical stimuli has been analyzed.
