Dr. Toshikazu Kuroda and Dr. Takeshi Ogawa from Advanced Telecommunications Research Institute International (ATR) visited us and gave us talks. Titles were “Behavior: How to conceptualize it, measure it, and analyze it” and “Development of brain-state prediction method based on EEG-fMRI simultaneous measurement and its application”. They also toured our laboratory, and we had the opportunity to exchange various opinions.
