Brain computer interface (BCI) is a device which allows the people to communicate without using their mouths or hands. The information about the subject's intention is issued by his brain and exists in his electroencephalogram (EEG), recorded from the scalp. Artefacts are noises introduced to the EEG signal by not central nervous system (CNS) sources of electric fields inside and outside human's body. The artefacts impede the analysis of the signal and should be handled properly. The most common and characteristic kind of artefacts are the electrooculographic (EOG) ones, especially subjects eye-blinking artefacts. In this paper an analysis of the power spectrum of eye-blinking artefacts is described with a connection of using the EEG for brain-computer interface (BCI), working with α- and μ-rhythms (range 8-13 Hz) brain potentials. The goal of the study is to determine the influence of the eye-blinks' power spectrum to the EEG.
