Characteristic of Spectral Exponent of Epileptic ECoG Data Corresponding to Levels in Wavelet-Based Fractal Analysis

چکیده
In this study, the wavelet-based fractal analysis is applied to analyze epileptic ECoG data obtained during nonseizure period and epileptic seizure events. The spectral exponents of the epileptic ECoG data obtained using the waveletbased fractal analysis from various intervals of levels are examined. The computational results show that the estimated spectral exponents of the epileptic ECoG epochs vary according to the levels m used in the estimation of slope of log 2 var(dm,n)m graphs. Also, it is shown that the spectral exponents of epileptic ECoG data obtained during epileptic seizure events are different from those of epileptic ECoG data obtained during non-seizure period. The most difference between the spectral exponents of epileptic ECoG data obtained during non-seizure period and epileptic seizure events is observed in the 125.0– 15.625 frequency band.

Examination of Multiple Spectral Exponents of Epileptic ECoG Signal
In this paper, the wavelet-based fractal analysis is applied to analyze an electrocorticogram (ECoG) signal recorded from an epilepsy patient. A spectral exponent γ yielded from the wavelet-based fractal analysis is determined from a slope of log 2 var(dm,n)-m graph over an interval of levels. Rather than a single spectral exponent, multiple spectral exponents determined from various intervals ...
متن کاملFractal spectral analysis of pre-epileptic seizures in terms of criticality.
The analysis of pre-epileptic seizure through EEG (electroencephalography) is an important issue for epilepsy diagnosis. Currently, there exist some methods derived from the dynamics to analyse the pre-epileptic EEG data. It is still necessary to create a novel method to better fit and explain the EEG data for making sense of the seizures' predictability. In this paper, a fractal wavelet-based ...
متن کاملPrediction of Epileptic Seizures in Patients with Temporal Lobe Epilepsy (TLE) based on Cepstrum analysis and AR model of EEG signal
Epilepsy is a chronic disorder of brain function caused by abnormal and excessive electrical neurons discharge in the brain. Seizures cause disturbances in consciousness that occur without prior notice, so their prediction ability, based on EEG data, can reduce stress and improve quality of life. An epileptic patient EEG data consists of five parts: Ictal, Inter-Ictal, pre-Ictal, Post-Ictal, an...

Background: Epilepsy is a severe disorder of the central nervous system that predisposes the person to recurrent seizures. Fifty million people worldwide suffer from epilepsy; after Alzheimer’s and stroke, it is the third widespread nervous disorder.Objective: In this paper, an algorithm to detect the onset of epileptic seizures based on the analysis of brain electrical signals (EEG) has b...
متن کاملAutomatic artifacts removal from epileptic EEG using a hybrid algorithm
Electroencephalogram (EEG) examination plays a very important role in the diagnosis of disorders related to epilepsy in clinic. However, epileptic EEG is often contaminated with lots of artifacts such as electrocardiogram (ECG), electromyogram (EMG) and electrooculogram (EOG). These artifacts confuse EEG interpretation, while rejecting EEG segments containing artifacts probably results in a sub...
