Outline of Annual Research Achievements

機能的磁気共鳴画像 (fMRI) を用いて，触覚刺激の同時判断と時間順序判断に関連する脳部位の違いを調べた研究成果を刊行した (Miyazaki et al. 2016, Sci Rep)．この研究によって，同時判断の関連脳部位として後島皮質が観測された．この研究に続き，さらに非時間的な統制課題を用いてfMRI測定を行った．具体的には，両手に与える触覚刺激の呈示時間と刺激用のピンの数を独立変数に設定し，参加者に同時判断と同数判断を課した．その実験の結果，同時判断の関連脳活動は後島皮質には認められず，右の下頭頂小葉に観測された (Kimura et al. & Miyazaki. 2015, Soc Neurosci; 木村ら & 宮崎. 2015, 日本臨床神経生理学会)．すなわち，後島皮質は同時判断と同数判断で同レベルの活動を示していた。この結果から，後島皮質は時間的一致性の検知を担う脳領域というよりも，より広汎な触覚刺激の一致性の検知に関与する領域であることが示唆された．右の下頭頂小葉については，Miyazaki et al. (2016) では同時判断の関連脳部位として検出されていなかったことから，時間順序判断にも関わっていたことが示唆される．近年，右の下頭頂小葉は刺激の時間長を表現しているとする報告が刊行されている (Hayashi et al. 2015, PLoS Biol)．この報告も考え合わせると，右の下頭頂小葉は触覚刺激の時間差を表現し，後島皮質がその時間差表現に基づき，同時/非同時を弁別しているというプロセスが本研究成果から示唆される．
