Abstract

In the present study, cortical potentials during online BCI experimentation were estimated by solving the inverse problem. The computer cursor was controlled by motor imagination in a standard BCI protocol. An approach of spectral spatiotemporal imaging of cortical potential was proposed and analysis results from online experiment revealed distinct localization of rhythmic activity for different tasks. The present pilot study again demonstrates the high spatial resolution of CPI compared to scalp potential and suggests its feasibility in BCI applications.
