A signal separation method for extracting background electroencephalogram (EEG) from EEG containing spikes was proposed. Morphological filters were designed for extracting spike waveforms, and then the background EEG was obtained by subtracting the detected spike waveforms from the EEG with spike. T

Abstract
Enhanced neuronal excitability or coherence, leading to a rapidβbursting mode of unit discharge or to synchronous polarization, underlies the electroencephalographic spike. The propensity for EEG spike activity to occur in relation to events that require absolute command of neural circuitry suggests that the EEG spike represents a mode of discharge of underlying neural elements which is employed for communication of imperative messages. Normal when confined to certain axial nuclei of the brain during sleep or during photic or sexual excitation, compensatory in response to deafferentation or hypoxia, this powerful transmission mode must have certain advantages to have persisted throughout evolutionary history.

## Abstract Measurement of the EEG during fMRI scanning can give rise to image distortions due to magnetic susceptibility, eddy currents or chemical shift artifacts caused by certain types of EEG electrodes, cream, leads, or amplifiers. Two different creams were tested using MRS and T2\* measuremen
Dual channel segmentation of the EEG signal has been developed. The purpose was to divide the signals into segments, according to information common for the two channels. The criterion for segmentation was based on the changes in the cross-spectrum of the two signals. It has been shown theoretically
