| Outline of Final Research Achievements |
Posterior parietal cortex (PPC) is considered related to the formation of intention. The intention specifies the goal of a movement and the type of a movement. It has been reported that EEG signals extracted from PPC can be used to decode intended movement direction before actual movement. However, visual cue was used for users in the experiment. It is not clear whether the extracted EEG signals were related to intentions. In this study, we conducted not only an experiment with visual cue but also an experiment with tactile cue. EEG components that could be related to PPC were extracted by using independent component analysis. Event-related potential (ERP) waveforms were observed in the experiment with visual cue. On the other hand, ERP waveforms obtained in the experiment with tactile cue were totally different from the one with visual cue. These results suggest that VEP was included in the EEG signals extracted from PPC in the experiment with visual cue.
