What is motivation for BCI? To provide new research paradigm to better understand how human brain works and processes information and to learn how information from different sensory streams (visual, auditory and somatosensory) is integrated in the brain and use this knowledge to build efficient neuro-engineering devices. In other words, why BCI is such an interesting and exciting field of research? First of all, it is a new paradigm in neuroscience which may help us to understand how the human brain works. The next reason is that the BCI allows you to expand possibilities for a human computer interface for rehabilitation and training. The third reason is to develop control electronic devices to assist elderly or partially paralyzed people.
