Outline of Annual Research Achievements |
漢字・仮名の「読み・書き」の機能の脳内機能領野の解明のため研究を推進した。術前評価に硬膜下電極を慢性留置した難治てんかん外科患者で研究に同意を得た者を対象とした。漢字/仮名読み課題に同期した皮質刺激介入を症例を追加して計5例で検討し、定量的な精神物理学的評価から、側頭葉底部前後方向に意味から形態認知への機能勾配を明らかにした(神経科学大会発表、論文準備中)。側頭葉前方領域が視覚性・聴覚性意味処理機能のハブ機能を有することを示した(神経科学大会、日本てんかん学会)。運動関連の皮質脳波の脳律動解析の手法を考案し(論文発表)、言語機能マッピングに応用できる皮質電気刺激に替わる低侵襲的脳機能マッピング法を確立した。また、低い刺激強度による言語機能マッピング法の有用性について提唱した(日本てんかん学会)。関連する領野間の脳機能結合地図の作成のため、電気的白質線維追跡法(皮質皮質間誘発電位 CCEP)によるネットワークマッピングの症例を蓄積した。漢字読み・仮名読みを含む言語課題の障害程度と、CCEPから同定した機能結合様式について定性的な相関を少数例で予備的にまとめた(臨床神経生理学会)優位半球側頭葉を切除領域に含む脳腫瘍症例において、術・前後の経時的神経心理検査と切除病変との対応から意味記憶の機能変容、可塑性を示した(神経心理学会)。11例の難治側頭葉てんかん患者において、側頭葉前方領域の切除前・後 1週間、1か月、6か月、1年と経時的な機能評価を行い、正答率およびエラー内容の検討し、側頭葉前方領域の漢字書字・読字機能が同部位の意味記憶に基づくことを明らかに、論文準備中である。
