Outline of Annual Research Achievements

(1)黄斑色素濃度,L/M錐体比を求めた被験者に対して条件等色実験を行った。三刺激値が等しいが黄斑色素吸収量が異なる刺激の等色点には青―黄方向で系統立った違いが見られ、黄斑色素濃度と強い相関が見られた。また、L/M錐体比については、日本人はコーカサス人種と比較し、有意に低いことがわかった。
(2) 被験者個人のERG法によって推定したL/M錐体比とユニーク色の波長及び色検出閾値を比較した。L/M錐体比とユニーク色波長とは相関がないこと、また、ΔL/L対ΔM/Mの錐体コントラスト平面上での色弁別閾値の輝度メカニズム線の傾きにはL/M錐体比と相関がある可能性が見られたが、L、Mノイズによる閾値の増大には相関が見られないことが示された。
(3)fMRIを用いて錐体応答拮抗型反対色とユニーク色に対する脳活動を計測し、初期視覚野における応答の特性について調べた。V4において脳活動パターンの再現性が課題による影響を受け、その違いがユニーク色に対する脳活動において統計的有意差を示す事がわかった。全脳の脳活動を課題間で比較した結果,色同定課題を行う際には視覚野(V1-V4)に加え前頭葉(MFG)や側頭葉(insula)の領野で有意な信号上昇も見られ、これらの領野からのフィードバックがユニーク色の見えの評価に関与していたことが明らかになった。
(4)L/M錐体比の個人差とユニーク黄の乖離について説明するために、まず、視環境の統計データ、物質のデータベースからシミュレーションによって、視覚刺激として生じやすい色度を明らかとした。感覚刺激として生じやすいものが、視覚認知の座である下側頭皮質においてどのように情報表現されているかを議論し、スパースコーディングによる応答特性の偏りが新しい環境光適応型色覚モデルには重要であること示した。
(5)830nmのAO-SLO法によるL/M錐体比測定の可能性を示した。
