| The purpose of the paper is to apply EEG spectral analysis to compare brain activity during Virtual Reality (VR) stimulation. This preliminary study covers analysis of EEG data from three participant at the age of 20–25. In the examination 10–20 EEG system was applied. The examination consists of resting state recording as well as five intervals with different VR simulation intended to evoke different emotions such as anger, fear or excitement. These scenarios were presented for participant with special goggles designed for displaying VR. Collected data has been subjected to preprocessing covering filtering and artifacts elimination and spectral analysis. As a result maps of power spectral from each intervals and wave band distribution were obtained. Changes were observed in alpha/theta ratio for various emotional sates. What is more, the amplitude value of alpha wave indicated strong changes among particular intervals. |
