Abstract:

The brain is an impressively complex information-processing organ which often eludes our ability to understand it. At any given time, the brain is collecting, filtering, and analyzing information and in response performs countless intricate processes. Cognitive neuroscience is one of the ways we have to understand the workings of our minds. It's the study of the brain biology behind our mental functions: a collection of methods like brain scanning and computational modeling combined with a way of looking at psychological phenomena and discovering where, why, and how the brain makes them happen. The science of brain cognitive behavior and interaction has attracted the interest of neuroscientists and researchers as a way to assist people with disabilities. The very first step deals with brain signal acquisition. Among variety of acquisition techniques including, high-end g.Tec g.USBamp and functional MRI, the EEG EPOC headset offered by Emotiv provides the possibility of running inexpensive experiments outside the labs for scholars. In the interest of exploiting these capabilities, we based g.Tec g.USBamp observations as a benchmark for further discussion on Emotiv EEG headset performance on a  visual-evoked related Brain Computer Interface study called Rapid Serial Visual Presentation paradigm or RSVP Keyboard. RSVP in brain computer interface domain is particularly useful for most users with weak or no-gaze control and for those whose cognitive skills do not allow processing matrix presentation of letters. In this study We provide a performance correlation between Emotiv EEG EPOC Neuroheadset and g.USBamp, using RSVP Keyboard starting with implementation of headset driver in BCI framework and finally running experiments using both methods.
