Investigation of the frequency characteristics of the electrodes for EEG measurement at high frequencies

The paper considers the problem of determining the applicability of the electrocardiographic electrodes to human brain electrical activity monitoring at high frequencies. Frequency response of the electrodes and their circuit models were investigated. The dependence of voltage transmission coefficient of the electrode at high frequencies is linear and does not contain any significant fluctuations, which allows using them for electroencephalogram recording in the range from 0 to 1 kHz.
