Abstract: The analysis of EEG signal is one of the objective methods used in alertness assessment. Many publications confirm the correct assessment of alertness level based on the analysis of selected brain waves. EEG registration is a difficult task; one of the important problems is the necessity to choose which EEG electrode to download the signal for analysis. The authors use different electrodes, often without justifying the choice. Equally often, the only justification is to say that the analyzed signal was the strongest among those available, or the least contaminated with artifacts. The aim of the article is to try to answer the question: signals which electrodes (channels) should be included in the alertness assessment. 33 participants took part in the experiment. Blue and red light was used to stimulate alertness. The impact of such light is documented in many publications. Alertness changes due to specific color of light were evaluated – the changes of alpha and beta bands were analy zed. Statistical analysis has shown that for alertness assessment the following electrodes should be considered: C3 and FC1 for alpha band and F3 and FP1 – for beta band signals. (More)
