Thesis Eeg Autoregressive

As a result of this clustering, elementary patterns are determined. The study was done using two types of signal simulated eeg data, which consisted of various sinusoidal signals plus gaussian noise, and actual eeg data recorded by intracerebral electrodes from patients undergoing complex partial seizures. The procedure involves the recursive computation of a fifthorder autoregressive model by means of a kalman filter.

Major findings of this study are (1) based on analysis of the simulated eeg data, the ar spectral analysis method is superior to the fft spectral analysis method in terms of frequency resolution, variance of the estimation and accuracy of time delay estimation. Eeg in short, stationary intervals, extract features and lump identical intervals together. .

The signal coherence and propagation routes change considerably during the initiation of the seizure, suggesting that this method could be extended to detect the starting point of seizure activity. These patterns represent the letters of an alphabet that can generate an eeg. In this paper, a method is described to evaluate the eeg by means of a piecewise analysis i.

Using the estimated time delays, the propagation routes through which seizure activity spreads were traced. The pathways by which epileptic seizures propagate through the brain are unknown. We use cookies to help provide and enhance our service and tailor content and ads.

By continuing you agree to the elsevier b. Zheng, jingsheng, autoregressive analysis of multichannel eeg spectra with application to epileptic seizure propagation (1990). The results of applying this method to sleep recordings are described in this paper.

This thesis gives results using the autoregressive (ar) spectral analysis method to estimate time differences of electrical activity between different sites of the brain and propagation routes of epileptic seizures. The overall result for propagation routes is consistent with the neurological assessment, although some pathways at variance with present neurological understanding of eeg signal propagation were found. This method may prove useful as a pre-surgical evaluation tool. Methodology developed and used in this study includes the eeg data acquisition software, the multichannel ar and the fft spectral analysis methods, and an automatic method for time delay estimation. These results indicate that the method is useful in extracting elementary patterns from an eeg and that the piecewise analysis approach is feasible.

    As a result of this clustering, elementary patterns are determined. These results indicate that the method is useful in extracting elementary patterns from an eeg and that the piecewise analysis approach is feasible. The ar method is more powerful and reliable its result is easily interpreted and it does not require any smoothing algorithm. This thesis gives results using the autoregressive (ar) spectral analysis method to estimate time differences of electrical activity between different sites of the brain and propagation routes of epileptic seizures. The letter statistics (or classification profiles), expressing the number of times each pattern occurs per eeg, are used in a second analysis to determine the eeg classification category.

    The signal coherence and propagation routes change considerably during the initiation of the seizure, suggesting that this method could be extended to detect the starting point of seizure activity. About 80 agreement with visual classification was obtained using one recording for training and five other eegs (four of which were recorded from two other subjects) for testing.
