Outline of Final Research Achievements

This study was conducted to discover the relations between silence during conversation and the corresponding brain activity from the result of simultaneous monitoring of EEG and NIRS signals. To identify the brain states, we cascade a system of two self-organizing maps (SOMs) in which the feature vectors have different segment lengths; that is, the segment length of a sample in the lower SOM is 1 sec and that in the upper is 30 sec. From the experimental results, the brain states of resting and listening were identified in 92% classification accuracy. The brain states of eye-closing, listening, writing answers and writing answers with listening were varied from 67% through 100% in classification accuracy, and we found that the conditions for situation recognition were different by the brain states.
