Summary:
This study aimed at investigating if CNV-like variations are elicited in Electroencephalograms (EEG) when people remember human continuous motion, and if it is possible to segment the continuous motion automatically by EEG. It is known that there are some important postures in continuous human motion, and the segments divided by the significant postures attract human attention. Since the situation is similar to Event-related brain potential (ERP) experiments, we expected that brain wave variations like Contingent Negative Variation (CNV) would also be elicited during motion remembering and it could be possible to detect the segmentation automatically from EEG. In this study, we used template matching and found that negative variations tend to precede segments divided by manually selected significant postures.
