An Improved Stimuli System for Brain-Computer Interface Applications

When developing a motion synchronous Brain-Computer Interface, it is very important to have effective stimuli. This research testes and proposes an improved brain computer interface stimulus system, based on event related spectral perturbation. In order to investigate the reaction of the motor cortex to stimuli, the influence of the human senses has to be investigated. Considering the limitations of human senses, the article proposes effective visual and auditory stimuli in two similar tasks, to gain accuracy and better reaction time ( RT) for real movements in Brain-Computer Interface synchronous systems.
