The EEG signal on each channel was decomposed to five levels using discrete wavelet transform. Formed wavelet coefficients and standard deviation of all 8-channel raw data to compute adaptive threshold, which applied on sub-bands1, 2 and 3. Then extracted the spike portion of EEG signal extracted from the raw data. The key points of this research work were identification of a suitable wavelet for decomposition of EEG signals, recognition of a proper resolution level, and computation of a dynamic threshold. The experiment results show that the proposed method offers a fast and effective measure for detecting epileptiform activity in human EEG. %K electroencephalogram(EEG) %K epileptiform activity %K multi-resolution analysis %K automatic detection
