61. Parametric segmentation of the EEG
... In general terms, the procedure of adaptive segmentation could be based on the estimation of the extent of similarity of an initial fixed interval of EEG with an EEG interval of the same duration viewed through the time window running along the EEG recording. ... Beyond the stationary segment to which the model parameters were fitted the prediction error will sharply increase, thus signalling the termination of the foregoing segment and the beginning of the next one. ...

62. Non-stationarities in EEG. Methods of segmentations of the EEG signal
... Assuming that the duration of a minimal stationary interval usually is no less than 2 s, as reported in (McEwen & Anderson 1975), the procedure of EEG segmentation into stationary fragments would consist of four stages. ... However, this segmentation method had a serious disadvantage that some of the fixed intervals should necessary fall on boundaries between the real stationary EEG segments. ... Let us now consider the main approaches to the adaptive segmentation of the EEG signal. ...

63. EEG feature extraction
... Application of the change-point analysis to the investigation of the brain's electrical activity. ... A vast variety of approaches to the extraction of quantitative features from an EEG signal was introduced during more than 70 years of electroencephalography. ... Therefore, statistical approaches seem to be the most feasible and theoretically satisfactory methodology for the quantitative analysis of the EEG signal up to now. ...

The EEG is also an effective tool for brain disease and traumatic lesion diagnostics. ... It is evident, however, that effective control of body functioning requires strict constraining of the number of degrees of freedom at all levels of the brain structural and functional hierarchy. ...

66. Other prospects of the change-point based analysis
Brain Research Group >> Research >> Change-point analysis ... << previous next >> . ... Unless in many other approaches to the analysis of different signal coupling, the information entering the analysis of synchronization in our approach is explicitly represented in the form of elementary, instantaneous events (the change-points). ... Hence the use of correlation/coherency estimates in parallel with change-point analysis seems to be quite rational. ...

67. Change-point synchronization between signals or signal components
Brain Research Group >> Research >> Change-point analysis ... << previous next >> . ... In this case the simultaneity of the occurrence of the change-points generated by different systems gives an evidence of some kind of connectivity in their functioning. Detailed information about signal generation, as well as constructing the model of the signal, is not required, only some concept of the functionally significant components composing the signal is helpful. ...

Brain Research Group >> Research >> Change-point analysis ... << previous next >> . ... It is necessary to note that a change-point detection method which we applied to a real EEG signal was developed on the basis of the piecewise stationarity model of the signal. ... The data presented in this Chapter demonstrate that the effective detection of the change-points opens the way for a number of new methods of the analysis of complex signals such as the EEG. ...

69. Spatial synchronization of the change-points
Brain Research Group >> Research >> Change-point analysis ... << previous next >> . ... It is naturally to treat the change-points appearing close in time in a number of EEG channels as a single complex. We will call it a change-point synchrocomplex , or simply synchrocomplex . ... The spatial configuration of the functionally connected areas may vary dramatically within even short time intervals, and this dynamics may manifest itself in change-point synchrocomplexes. ...

70. Change-point synchronization in pairs of EEG channels
... The most usual indices for functional association between two brain areas are the linear correlation coefficient and coherency estimations computed for a pair of EEG channels. ... The index of change-point coincidence was also found to be sensitive to the condition of open/closed eyes and the interindividual differences in state anxiety, which are other factors influencing the alpha activity. ... Pairs of EEG electrodes where alpha change-point coincidence correlated with state anxiety . ...

71. Analysis of change-point synchronization in multi-channel EEG
Brain Research Group >> Research >> Change-point analysis ... << previous next >> . ... The number of randomly coinciding change-points (the noise level) can be easily estimated using the total numbers of change-points in each EEG channel, and thus the estimate of the number of systematically coinciding change-points can be cleared from the randomly coinciding change-points, both "true" and "false". ... This number, however, vary with the number of change-points in each channel. ...
