SYSTEMS AND METHODS FOR TRACKING NON-STATIONARY SPECTRAL STRUCTURE AND DYNAMICS IN PHYSIOLOGICAL DATA

摘要

To provide systems and methods for observing dynamic structure in physiological data.SOLUTION: The method includes providing physiological data, including electroencephalogram ("EEG") data, acquired from a subject, and assembling a time-frequency representation of signals from the physiological data. The method also includes generating a dynamic model of at least one non-stationary spectral feature, such as at least one non-stationary spectral peak, using the time-frequency representation and a user indication, and applying a dynamic model of at least one non-stationary spectral feature in a parameter estimation algorithm to compute concurrent estimates of spectral parameters representing the at least one non-stationary spectral feature. The method also includes observing the spectral parameters of the at least one spectral feature over time.SELECTED DRAWING: Figure 1B
