| Abstract(in English) | For the development of BCIs (Brain-Computer Interfaces) extracting brain information with high accuracy, quantitative evaluation of noises superimposed on signals is necessary. The present study focused on a BCI based on SSSEPs (Steady-State Somatosensory Evoked Potentials) and simulated SSSEPs to investigate ability of the BCI..Sinusoidal source signals with fluctuation and background noises were assumed to be generated from the right and left SI (Primary Somastosensory Cortex). Simulated SSSEPs were obtained from the sinusoidal signals by forward problem in an eccentricity three layered sphere model. Simulated data were made by superimposing noises with different signal-to-noise ratio on the simulated SSSEPs. We proposed a novel discriminant method using spectra of PC (Principal Component) score obtained by PCA (Principal Component Analysis) and compared its performance with that of sLORETA (standardized low-resolution brain electromagnetic tomography) by applying the two methods both to simulated and measured data. |
