Bispectral Analysis of the Electroencephalogram Predicts.

Bispectral Analysis Essay

Abstract - This paper provides a tutorial for bispectral analysis, a signal processing technique commonly used for the analysis of the Electroencephalogram (EEG). The use of this technique has been hindered by popular misconceptions deriving from existing tutorial papers. INTRODUCTION Analysis of EEG is typically performed.

Bispectral Analysis Essay

Bispectral analysis, in which three-wave correlations are used to determine the linear growth rates and nonlinear transfer rates of a turbulent system, is a useful tool for comparing experiment and theory in plasma experiments. Unfortunately, currently available algorithms are only able to process a single field.

The monitor uses bispectral analysis to derive an index of anaesthetic depth, the bispectral index (BIS). We compared reliability, impedance and BIS for each montage. ECG electrodes placed in a bifrontal montage were more reliable than silver dome electrodes in a fronto-central montage and both types of electrodes had impedances in the clinically useful range.

The results presented here confirm the capacity of bispectral techniques to identify a quadratically nonlinear mechanical system that possesses chaotic motions. For the chaotic case, cross-bicoherence spectra indicate that most of the nonlinear energy transfer between the modes is owing to cross-coupling between phase modulations rather than between amplitude modulations.

Bispectral analysis is a new quantitative technique that measures the consistency of the phase and power relationships and returns a single measure, the bispectral index. The purpose of this study was to compare the performance of the bispectral index, version 1.1, with other spectral analysis EEG measures of drug effect for three commonly used anesthetic drugs.

Bispectral Analysis Essay

Bispectral analysis was used in earlier studies to examine nonlinear energy transfers within the oceanic internal wave field (McComas and Briscoe 1980; Lin et al. 1995; Niwa and Hibiya1997; Furue 1998, 2003). It should be noted that not only resonant interactions but all kinds of triad interactions are taken into account in Eqs. and.

RESULTS Multiple regression analysis showed that end-tidal sevoflurane concentration and age significantly affected both bispectral index and 95% spectral edge frequency. ED50 values of sevoflurane concentration for loss of consciousness, defined as no response to verbal command, were different between groups A and C: 0.72 (95% confidence interval: 0.68-0.75) versus 0.59 (95% confidence.
