Abstract :
The event-related (de)synchronization (ERD/ERS) phenomenon is used to build motor imagery Brain Computer Interface (BCI) system. Common Spatial Pattern (CSP) algorithm is mainly applied to extract feature in mu rhythm. However there is no evidence to prove the features are directly related to ERD/ERS phenomenon. In this paper we design the experiment to analyze the relationship between the feature extracted by CSP algorithm and the ERD/ERS phenomenon. The experiment contains two methods of Band Power and CSP for the comparison. The result shows that there is low correlation between the MI system based on CSP and the ERD/ERS.
