Abstract

In this paper, the analysis of electric circuit of the electrode system used at EEG is presented. Registration of cerebral cortex signals, or EEG, allows to carry out monitoring of brain activity and is the best diagnostic method for revealing pathological conditions of a brain, for example, epilepsy. Frequency dependence of transfer function of electrode system is determined by character of circuit impedances and essentially depends on electrode type. The opportunity of use of non-gel contact system is also shown
