線条体の自発Ca^<2+>濃度上昇に大脳皮質運動野の活動が与える影響

小山内実,山田尚宏,大星文人 [他],八木哲也
電子情報通信学会技術研究報告. NC, ニューロコンピューティング 104(759), 1-5, 2005-03-22
大脳皮質-線条体投射は大脳皮質-基底核ループの主な入力部である。しかし、皮質の活動が線条体の細胞に与える影響については未だに良く分っていない。そこで我々は、大脳皮質の活動が線条体の自発活動に与える影響を調べるために、線条体の細胞に対して細胞内カルシウム([Ca^<2+>]_i)イメージングを行った。その結果、大脳皮質-線条体スライス中の線条体の細胞において、数秒から数百秒に渡る自発的な …
