国際シンポジウム

COE 国際シンポジウム（第 31 回生理研国際シンポジウム）
第 31 回生理研国際シンポジウムは“感覚運動機能研究への多様なアプローチ--新しい研究パラダイムによる最新の展開--”と題して 2004 年3 月 16-18 日の 3 日間，岡崎コンファレンスセンターにおいて開催された。今回のシンポジウ
ムは脳による運動制御について，脊髄・脳幹レベルから大脳皮質，大脳基底核，小脳といった様々な領域の機能やその損傷時の機能代償機構などについて，その神経回路の分子的構築から神経活動による情報の符号化，さらにはコンピューターモデリングによる計算論的研究まで，まさしく multidisciplinary な研究手法を有する研究者同士の活発な交流を目指して企画された。そしてこの分野の世界的に第一線で活躍する研究者（国内 16 名，海外より 20 名）を招聘し，講演していただいた。これらの講演は 3 日間にわたり行われたが，それに加えてポスターセッションも行い，そこでも国内外より 84 題のポスター発表が行われた。最終的な参加者は総勢 220 名（国内 194 名，海外より 26 名）で，この分野の国際会議としては質・量ともに近年例のない大規模なものとなった。今回顕著だったことは多くの若手研究者の参加をみたことで，様々な研究手法を融合することで，脳による運動制御の研究が今後新たな展開を見せることを十分に期待させるものであった。
