Feature Extraction on Brain Wave Activities in Rapid Serial Visual Presentation Stimulus

The images stimulus that appear rapidly and contain different frequencies might have an effect on brain activities. This paper proposed how to determine a rapid visual stimulus and its effects to the brain activities. The stimulus that used in this paper is the Rapid Serial Visual Presentation (RSVP) in the shape of London’s aerial images. This stimulus are presented with three kinds of frequencies that are 5 Hz, 6Hz, and 10 Hz. The RSVP stimulus is often used to determine the changes of brain activities that connected to attention and concentration level. Our works were analyzing the changing of EEG waves (Alpha and Gamma) and the EEG spectral. The outcomes represented of brain activities in the occipital and parietal areas. The results shown the 5 Hz of RSVP stimulus had the most influences to the brain hemispheres.
