Outline of Final Research Achievements

The purpose of this study is to improve the accuracy of brain-computer interface (BCI) by detecting intention-related brain activities from EEG and MEG data. To this end, from EEG during motor imagery, we revealed waveforms that occur with unknown delays after stimulus onset (unlocked waveform). We proposed a procedure to examine the roles of unlocked waveforms. Furthermore, we proposed a method to estimate repetitive spatiotemporal patterns from resting-state brain activity data.
