Wavelet analysis of epileptic spikes.
Interictal spikes and sharp waves in human EEG are characteristic signatures of epilepsy. These potentials originate as a result of synchronous pathological discharge of many neurons. The reliable detection of such potentials has been the long standing problem in EEG analysis, especially after long-term monitoring became common in investigation of epileptic patients. The traditional definition ...
متن کاملAnalysis Of Epileptic Events Using Wavelet Packets
Many studies have focused on the nonlinear analysis of electroencephalography mainly for the characterization of epileptic brain states. The spatial and temporal dynamics of the epileptogenic process is still not clear completely especially the most challenging aspects of epileptology which is the anticipation of the seizure. Despite all the efforts we still don’t know how and when and why the ...
متن کاملA Simple Wavelet Method for Automated Detection of Epileptic Neural Spikes in Electroencephalogram
In clinical diagnosis process of epilepsy, the physicians rely on tedious visual screening of long time recorded electroencephalograms (EEG) for detection and localization of important epileptic events. This process is very time consuming and there is also possibility of making wrong diagnosis owing to tiredness or to subjectivity of the specialist. Therefore, the computer-assisted diagnosis sy...
متن کاملAnalysis and localization of epileptic events using wavelet packets.
This article compares results obtained in previous studies using time-frequency representations (Wigner-Ville, Choi-Williams and Parametric) and the wavelet transform with those obtained with wavelet packet functions to show new findings about their quality in the analysis of ECoG recordings in human intractable epilepsy: data from 21 patients have been analyzed and processed with four types of...
متن کاملEEG Analysis with Epileptic Seizures using Wavelet Transform
Electroencephalograph (EEG) recordings of five patients suffering from different epileptic seizures are analyzed using a wavelet transform. The energy of EEG signals at the different frequency bands is calculated for detecting the behaviors of brain during epileptic seizures. The energy change of each frequency band is indicated as a feature by calculating the Euclidean distance between a refer...
